SAFETY INSTRUCTIONS

DANGER

Before turning on the radar, make sure that there is no one near the scanner unit.

Serious injury or even death may result if a rotating antenna strikes someone standing nearby.

WARNING

Radio Frequency Radiation Hazard

The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the antenna aperture from a close distance while the radar is in operation or expose yourself to the transmitting antenna at a close distance.

i

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Only qualified personnel should work inside the equipment.

Turn off the radar power switch before servicing the scanner unit. Post a warning sign near the switch indicating it should not be turned on while the scanner unit is being serviced.

Prevent the potential risk of being struck by the rotating scanner and exposure to

RF radiation hazard.

Wear a safety belt and hard hat when working on the scanner unit.

Serious injury or death can result if someone falls from the radar scanner mast.

Do not disassemble or modify the equipment.

Fire, electrical shock or serious injury can result.

Turn off the power immediately if water leaks into the equipment or the equipment is emitting smoke or fire.

Continued use of the equipment can cause fire or electrical shock.

WARNING

Do not place liquid-filled containers on the top of the equipment.

Fire or electrical shock can result if a liquid spills into the equipment.

Do not operate the equipment with wet hands.

Electrical shock can result.

Keep heater away from equipment.

Heat can alter equipment shape and melt the power cord, which can cause fire or electrical shock.

CAUTION

Do not use the equipment for other than its intended purpose.

Use of the equipment as a stepping stool, for example, can result in personal injury or equipment damage.

No one navigation device should ever be solely replied upon for the navigation of a vessel.

Always confirm position against all available aids to navigation, for safety of vessel and crew.

ii

ARPA Safety Instructions

WARNING

No one navigational aid should be relied upon for the safety of vessel and crew.

The navigator has the responsibility to check all aids available to confirm position. Electronic aids are not a substitute for basic navigational principles and common sense.

•

This auto plotter automatically tracks an

automatically or manually acquired radar

target and calculates its course and

speed, indicating them by a vector. Since

the data generated by the auto plotter

are based on what radar targets are

selected, the radar must always be

optimally tuned for use with the auto

plotter, to ensure required targets will not

be lost or unwanted targets such as sea

returns and noise will not be acquired

and tracked.

•

A target does not always mean a land-

mass, reef, ships or other surface vessels

but can imply returns from sea surface

and clutter. As the level of clutter changes

with environment, the operator should

properly adjust the A/C SEA, A/C RAIN

and GAIN controls to be sure target

echoes are not eliminated from the

radar screen.

CAUTION

The plotting accuracy and response of this auto plotter meets IMO standards.

Tracking accuracy is affected by the following:

•

Tracking accuracy is affected by course

change. One to two minutes is required to

restore vectors to full accuracy after an

abrupt course change. (The actual

amount depends on gyrocompass

specifications.)

•

The amount of tracking delay is inversely

proportional to the relative speed of the

target. Delay is on the order of 15—30

seconds for high relative speed; 30—60

seconds for low relative speed.

Display accuracy is affected by the following:

•

Echo intensity

•

Radar transmission pulsewidth

•

Radar bearing error

•

Gyrocompass error

•

Course change (own ship or target)

iii

Several labels are attached to the display unit and scanner unit.Do not remove these labels.

If a label is peeling off or is illegible, contact a

FURUNO agent or dealer.

- IMO A.820(19): Performance standards for navigational radar equipment for high speed craft

(1.1.1996 and after)

- IEC 60936-2: Performance standards for navigational radar equipment for high speed craft

Models

This series of radar and ARPA is available in the following models:

Model Freq configuration

Note: FR-2155, FR-2155-B, FR-2165DS are not IMO type-approved models.

All comes with the EPA (Electronic Plotting Aid) standard fitted. An optional ARP-26 board is available to provide the full functionality of ARPA (Automatic Radar Plotting Aid). Also with an optional Video Plotter RP-26 board.

Besides the choice of the above models, the FR-2105/2105-B Series is available in the Regular

type (R-type) and IMO type. The IMO type is designed as a primary radar under the 1974

SOLAS Convention on ships below 10,000 GT and also as a high speed craft radar when fitted with ARPA function (at least ATA by IEC 60936-2). The R-type satisfies the IMO and IEC standards but includes more flexibility of functionality to meet the fishing boats particularly

(thus, this is an expanded type in other word). ix

The table below shows the differences between R-type and IMO type radars. Other functions and specifications are common. The operator cannot navigate between these two types. Your radar is factory set for IMO type. If you want an R-type, please ask your service representative.

Precautions for high speed targets

! Assume your ship is making 40 kt and a target ship is approaching at 40 kt right toward you.

Then the relative speed is 80 kt. With the antenna revolving at 42 rpm, the target blip appears jumping to a new location 59 m nearer. This jump corresponds to 19 mm on the

300 mm display using the 0.25 nm range scale. On such a short range you may lose the track of target in the midst of sea clutter, random noise or other targets. Use one step larger range scale.

! ARPA can fail to track a target when the relative speed exceeds 100 kt. xiii

Chapter 1 OPERATION

Before turning on the radar, make sure that there is no one near the antenna unit.

Serious injury or even death may result if a rotating antenna strikes someone standing nearby.

Power switch

Control head

1.1 Turning on the Power

The POWER switch is located at the left corner of the control head. Push it to switch on the radar system. To turn off the radar, push it again. The screen shows the bearing scale and digital timer in approximately 15 seconds after power-on. The timer counts

down three minutes of warm-up time. During this period the magnetron, i.e., transmitter tube, is warmed for transmission. When the timer has reached 0:00, the indication STBY appears indicating that the radar is now ready to transmit pulses.

In warm-up and standby condition, you will see the message BRG SIG MISSING. This is normal because a bearing (azimuth) signal is not yet generated when the antenna is not rotating. ON TIME and TX TIME values shown at the bottom of the screen are the time counts in hours and tenths of hour when the radar has been powered.

-1.

1.2 Transmitter ON

When the STANDBY status is displayed on the screen, press the transmit switch labeled

STBY/TX on the control panel of the display unit.

The radar is initially set to previously used range and pulsewidth. Other settings such as brilliance levels, VRMs, EBLs and menu option selections are also set to previous settings.

The transmit switch toggles the radar between STANDBY and TRANSMIT status. The antenna stops in STANDBY status and rotates in TRANSMIT status.

Quick Start

Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can turn the radar into TRANSMIT condition without 3-minutes standby. If the Power Switch has been turned off by mistake or the like and you wish to restart the radar promptly, turn on the Power Switch not later than 10 seconds after power-off.

Notes:

1) If the antenna does not rotate in TRANSMIT status, check whether the antenna switch in the tuning compartment is in the OFF position.

2) The magnetron ages with time resulting in a reduction of output power. It is highly recommended that the radar be set to STANDBY status when not used for an extended period of time.

1.5 Tuning the Receiver

Tuning method can be selected at RADAR 3 menu; auto or manual.

1. Press the RADAR MENU key.

2. Press [0], [0], [2], [0] and [0] in sequence to reach the RADAR 3 menu item.

3. Press the [9] key twice to change between Auto and Manual.

4. Press the ENTER key to confirm your selection.

5. Press the RADAR MENU key to close the menu.

Automatic tuning

The radar receiver is tuned automatically each time the power is turned on; thus, there is no front panel control for tuning. The tuning indicator and the label AUTO TUNE at the top right corner of the display unit show the tuning circuit is working.

Manual tuning

If you are not satisfied with the current tune setting, follow these steps to fine-tune the receiver:

TUNE control ERROR lamp (See next page.)

1. Set the tuning method to manual as described above.

2. While observing the picture on the 48 mile scale, slowly adjust the TUNE control in the tune compartment and find the best tuning point.

3. Make sure that the radar has been set to the best tuning point. This condition is where the tuning indicator lights to about 80% of its total length. Note that the tuning indicator will never extend to full length.

-1.

Video Freeze-up Recovery

Video freeze-up or lock-up can occur unexpectedly on any digital rasterscan radars. This is mainly caused by heavy spike noise in the power line and can be noticed by carefully watching the nearly visible sweep line. If you suspect that the picture is not updated every scan of the antenna or no key entry is accepted notwithstanding the apparently normal pictures, do Quick Start to restore normal operation.

1. Turn off the Power Switch and within 10 seconds turn it on again.

2. Press the Transmit switch labeled STBY/TX for transmit condition.

NOTE: This equipment has self-diagnostic function to check operational software periodically. If any trouble has been found, the ERROR lamp lights. In this case, do the above procedure.

Head-up TB (True Bearing) mode

Radar echoes are shown in the same way as in the head-up mode. The difference from normal head-up presentation lies in the orientation of the bearing scale.

The bearing scale is compass stabilized. That is, it rotates in accordance with the compass signal, enabling you to know own ship’s heading at a glance.

This mode is available only when the radar is interfaced with a gyrocompass.

If the compass fails, the bearing scale returns to the state of head-up mode.

Own ship and other moving objects move in accordance with their true courses and speed. In ground stabilized

TM, all fixed targets, such as landmasses, appear as stationary echoes. In the sea stabilized TM without set and drift inputs, the landmass can move on the screen.

When own ship reaches a point corresponding to 75% of the radius of the display, it is automatically reset to a point of 75% radius opposite to the extension of the heading marker passing through the display center. Resetting can be made at any moment before the ship reaches the limit by pressing the [CU, TM reset]. Automatic resetting is preceded by a beep sound.

If the compass fails, the mode is changed to the head-up and the north marker disappears. The HDG readout shows asterisks (***.*) and the message GYRO appears in red at the lower-right corner of the screen.

1.11 Selecting the Pulselength

The pulselength in use is displayed at the upper-left position of the screen using the abbreviations shown in the table below.

Appropriate pulselengths are preset to individual range scales and function keys. Therefore, you are not usually required to select them. If you are not satisfied with the current pulselength settings, however, it is possible to change them by the Radar menu operation shown below.

You can choose the pulselength 1 or 2 on the scales 0.5 to 24 nm ranges on FR-2115/2125 models (0.75 to 24 nm ranges on the other models).

Selecting pulselength 1 or 2

1. Press the RADAR MENU key to display the FUNCTIONS 1 menu.

2. Press the [6] key to select PULSELENGTH 1 or 2 as appropriate.

3. Press the RADAR MENU key to close the FUNCTIONS menu.

Presetting pulselengths 1 and 2

Pulselength 1 and 2 can be preset on the PULSE WD 1 and 2 menus. Shown below are examples of the pulselength setup procedure:

1. To enable selection of S1 (0.07 µs) and S2 (0.15 µs) pulselength on the 0.5 nm range on

FR-2115/2125/2115-B/2125-B model, select S1 at 0.5 nm on the PULSE WD 1 menu and

S2 at 0.5 nm on the PULSELENGTH 2 menu.

2. To enable selection of S2 (0.15 µs) and M1 (0.3 µs) pulselength on the 3 nm range on

FR-2115/2125/2115-B/2125-B model, select S2 at 3 nm in the PULSE WD 1 menu and

M1 at 3 nm in the PULSE WD 2 menu.

A longer pulse provides an increased detection range, but with reduced discrimination. If you need discrimination in preference to detection, choose a shorter pulse.

Example: To select S1 (0.07 µs) as Pulselength 1 for the 0.5 nm range, display the

PULSELENGTH 1 menu following the steps shown above and hit the [2] key to choose "0.5

NM." Further hit the [2] key until the menu option "S1" is highlighted to the right of "0.5

NM."

1.12 Adjusting the Sensitivity

The GAIN control is used to adjust the sensitivity of the receiver, and thus the intensity of echoes as they appear on the screen. It should be adjusted so that speckled background noise is just visible on the screen.

To become acquainted with the way the GAIN control works, try rotating it between fully counterclockwise and clockwise positions while observing the radar picture. You will notice that clockwise rotation increases the echo intensity level. A low gain setting results in the loss of weak echoes and a reduced detection range. If you turn the GAIN control too far clockwise for an excessive gain setting, desired echoes will be masked in the strong background noise.

Manual anti-clutter control

From the fully counterclockwise position, slowly turn the A/C SEA control clockwise. For optimum target detection, you should leave speckles of the surface return slightly visible.

The anti-clutter sea control is often referred to as STC (Sensitivity Time Control) which decreases the amplification of the receiver immediately after a radar pulse is transmitted, and progressively increases the sensitivity as the range increases.

A common mistake is to over-adjust the A/C SEA control so that the surface clutter is completely removed. By rotating the control fully clockwise, you will see how dangerous this can be; a dark zone is created near the center of the screen and close-in targets can be lost.

This dark zone is even more dangerous if the gain has not been properly adjusted. Always leave a little surface clutter visible on the screen. If no surface clutter is observed (on a very calm water), set the control at the fully counterclockwise position.

-1.17-

1.14 Suppressing Precipitation Clutter

In adverse weather conditions, clouds, rain or snow produce a lot of spray-like spurious echoes and impairs target detection over a long distance. This situation can be improved by using a function key provided that it is so programmed. If the function key fails to offer a favorable suppression of the rain clutter, adjust the A/C RAIN control on the front control head.

The A/C RAIN control adjusts the receiver sensitivity as the A/C SEA control does but rather in a longer time period (longer range). Clockwise rotation of this control increases the anticlutter effect.

1.15 Interference Rejector

Mutual radar interference may occur in the vicinity of another shipborne radar operating in the same frequency band (9 GHz for

X-band, 3 GHz for S-band). It is seen on the screen as a number of bright spikes either in irregular patterns or in the form of usually curved spoke-like dotted lines extending from the center to the edge of the picture. This type of interference can be reduced by activating the interference rejector circuit.

The interference rejector is a kind of signal correlation circuit. It compares the received signals over successive transmissions and suppresses randomly occurring signals. There are three levels of interference rejection depending on the number of transmissions that are correlated. These are indicated by the legends IR1, IR2 and IR3 at the upper-left position of the screen.

Note: For stable reception of certain types of radar beacons (Racons) or SART (Search and

Rescue Radar Transponder) as required by SOLAS 1974 as amended 1988 (GMDSS), it is recommended to turn the interference rejector off.

1.16 Measuring the Range

Use the fixed range rings to obtain a rough estimate of the range to a target. They are concentric solid circles about own ship, or the sweep origin. The number of rings is automatically determined by the selected range scale and their interval is displayed at the upper-left position of the screen.

1.17 Measuring the Bearing

Use the Electronic Bearing Lines (EBLs) to take bearings of a target. There are two EBLs, No.

1 and No. 2, which are toggled by successive presses of the EBL ON key. Each EBL is a straight dashed line extending out from the own ship position up to the circumference of the radar picture. The fine dashed line is the No. 1 EBL and the coarse dashed one is the No. 2

EBL.

Press the EBL ON key to display either of the EBLs.

Successive presses of the EBL ON key toggle the active EBL between No. 1 and No. 2 and the currently active EBL readout is circumscribed by >...

Rotate the EBL rotary control clockwise or counterclockwise until the active EBL bisects the target of interest, and read its bearing at the lower-left corner of the screen.

The EBL readout is affixed by "R" (relative) if it is relative to own ship's heading, "T" (true) if it is referenced to the north, as determined by RADAR 2 menu settings.

Each EBL carries a range marker, or a short line crossing the EBL at right angles and its distance from the EBL origin is indicated at the VRM readout whether or not the corresponding VRM is displayed. The range marker changes its position along the EBL with the rotation of the VRM control.

Press the EBL OFF key to erase each EBL.

1. Press the EBL ON key to display or activate an EBL (No. 1 or 2).

2. Place the cursor (+) on a target appearing as threatening (A in the illustrated example) by operating the trackball.

3. Press the EBL OFFSET key on the mode panel, and the origin of the active EBL shifts to the cursor position. Press the EBL OFFSET key again to anchor the EBL origin.

4. After waiting for a few minutes (at least 3 minutes), operate the EBL control until the EBL bisects the target at the new position (A'). The EBL readout shows the target ship's course, which may be true or relative depending on the settings on the RADAR 1 menu.

If relative motion is selected, it is also possible to read CPA (Closest Point of Approach) by using a VRM as shown below (Figure (a)). If the EBL passes through the sweep origin

(own ship) as illustrated (Figure (b)), the target ship is on a collision course.

5. To return the EBL origin to the own ship's position, press the EBL OFFSET key again.

1.19 Measuring Range and Bearing Between Two Targets

Press the EBL OFFSET key, and place the origin of No. 1 EBL, for example, on a target of interest (target 1 in the illustrated example) by operating the trackball.

Turn the EBL control until the EBL passes through another target of interest (target 2).

Turn the VRM control until the range marker aligns with target 2. The active VRM readout at the lower-right corner of the screen indicates the distance between the two targets.

You can repeat the same procedure on third and forth targets (targets 3 and 4) by using No. 2

EBL and No. 2 VRM.

Bearing is shown relative to own ship with suffix "R" or as a true bearing with suffix "T" depending on EBL relative/true settings on the RADAR 1 menu. To return the EBL origin to the own ship position, press the EBL OFFSET key again.

1.20 Setting a Target Alarm Zone

CAUTION

The target alarm feature should never be relied upon as the sole means for detecting the risk of potential collision. The operator of a ship is not relieved of the responsibility to keep lookout for avoiding collisions, whether or not the radar is in use.

The target alarm serves to alert the navigator to targets (ships, landmasses, etc.) entering a certain area with visual and audible alarms.

-1.23-

The zone has a fixed width of 0.5 nm in the radial direction (depth) and is adjustable only within 3.0 to 6.0 nm from own ship. On the R-type, the outer and inner boundaries can be set at any distance. On any radar type, the sector of the zone can be set anywhere between 0 and

360 degrees in any direction.

To set a target alarm zone:

1. Place the cursor (+) at point "A" (see figure below) using the trackball.

2. Press the RADAR MENU key to show the FUNCTION 1 menu.

3. Press [2] key to set start point (point "A") of the alarm zone. The message TGT ALARM 1

(or 2) SET appears at the bottom-right corner of the screen.

4. Move the cursor (+) to point "B" and press the [2] key again. Then, the target alarm zone as illustrated is created and the label TGT ALARM 1 (or 2) appears instead of TGT ALARM

1 (or 2) SET at the lower-right corner of the screen.

Note: If you wish to create a target alarm zone having a 360-degree coverage around own

ship, set point "B" in almost the same direction (approx. ±3°) as point "A" and press the [2] key.

If you change the range scale to less than half of the TAZ, the warning TGT ALARM 1 (or

2) OUT appears instead of TGT ALARM 1 (or 2).

5. Two alarm zones can be set as described above. Press [ENTER] and [2] keys in that order while displaying the FUNCTION 1 menu and repeat the above steps.

Target alarm zone (TAZ) can be set in any sector between 3 and 6 nm on IMO-type, or anywhere on the R-type.

When the radar has an ARPA board ARP-26, a total of 4 alarm zones (2 each TAZ and GZ) may be set.

The 2nd TAZ or 2nd GZ is available only when the

1st TAZ or 1st GZ is valid.

Acknowledging alarm

A target entering the watch zone produces both visual (flashing) and audible (beeping) alarms.

To silence the audible alarm, press [2] key shortly on the FUNCTION 1 menu and the label

TGT ALARM 1 ACK replaces TGT ALARM 1 on the display.

This will deactivate the audible alarm but will not stop the flashing of the target in the guard alarm zone. To reactivate the audible alarm, press [2] key again on the FUNCTIONS 1 menu.

When an external buzzer is connected, the audible alarm does not stop until deactivation of the guard alarm.

-1.24-

Deactivating guard alarm

Hold the [2] key depressed for at least 5 seconds on the FUNCTION 1 menu. In the IMO type, deactivation of TAZ 1 deactivates TAZ 2. TAZ 1 and 2 work independent in the Regular type.

Note: The echo watch alarm is given to targets having a certain level of echo strength. This

level does not always imply a landmass, reef, ships or other surface objects but can mean returns from the sea surface or precipitation. Properly adjust the GAIN, A/C SEA, and A/C

RAIN controls to reduce noise to avoid generation of an alarm against false target.

Inward and outward guard alarms

On the R-type, an inward or outward guard alarm can be selected on the RADAR 2 menu. On the IMO type, only the inward guard alarm is available. The inward guard alarm generates visual and audible warnings when a target enters the guard zone from any direction. The outward guard alarm is produced when a target leaves the guard zone (This is not a guard zone by definition but some users find this feature valuable).

(a) Inward guard

1.21 Off-Centering

Own ship position, or sweep origin, can be displaced to expand the view field without switching to a larger range scale. The sweep origin can be off-centered to the cursor position, but not more than 75% of the range in use; if the cursor is set beyond 75% of the range scale, the sweep origin will be off-centered to the point of 75% of the limit.

This feature is not available on the longest range scale. The number of range rings increases keeping the original range intervals unchanged.

To off-center the radar picture:

1. Place the cursor at a position where you wish to move the sweep origin by operating the trackball.

2. Press the OFF CENTER key. Then, the sweep origin is off-centered to the cursor position.

3. To cancel off-centering, press the OFF CENTER key again.

The picture cannot be off-centered in the true motion mode.

-1.25-

1.22 Echo Stretch

On long ranges target echoes tend to shrink in the bearing direction, making them difficult to see. On short and medium ranges such as 1.5, 3 and 6 nm scales, the same size targets get smaller on screen as they approach the own ship. These are due to the inherent property of the radiation pattern of the antenna. To enhance target video, use the echo stretch function. There are 3 settings: echo stretch 1 (ES1) to enlarge in bearing direction for long range detection, echo stretch 2 (ES2) to enlarge in range direction and echo stretch 3 (ES3) to enlarge in bearing and range directions.

To activate the echo stretch:

1. Press the RADAR MENU key to show the FUNCTIONS 1 menu.

2. Press the [0] key to display the FUNCTIONS 2 menu.

3. Press the [3] key to select ECHO STRETCH.

4. Press [3] until Echo Stretch option 1, 2, 3 or OFF as desired is highlighted.

5. Press the ENTER key to conclude your selection followed by the RADAR MENU key to close the FUNCTIONS menu. Selected setting is marked on the left side of the radar display.

Notes:

1) If the 1.5 nm range is preset with a pulselength of S1 or S2, and the 3 nm scale with S2, the echo stretch is not available on these range scales.

2) The echo stretch magnifies not only small target pips but also returns (clutter) from sea surface, rain and radar interference. For this reason make sure these types of interference have been sufficiently suppressed before activating this function.

1.23 Echo Averaging

The echo average feature effectively suppresses sea clutter. Echoes received from stable targets such as ships appear on the screen at almost the same position every rotation of the antenna. On the other hand, unstable echoes such as sea clutter appear at random positions.

To distinguish real target echoes from sea clutter, this radar performs scan-to-scan correlation.

Correlation is made by storing and averaging echo signals over successive picture frames. If an echo is solid and stable, it is presented in its normal intensity. Sea clutter is averaged over successive scans resulting in the reduced brilliance, making it easier to discriminate real targets from sea clutter.

To properly use the echo average function, it is recommended to first suppress sea clutter with the A/C SEA control and then do the following:

Echo averaging uses scan-to-scan signal correlation technique based on the true motion over the ground of each target. Thus, small stationary targets such as buoys will be shown while suppressing random echoes such as sea clutter. True echo average is not however effective for picking up small targets running at high speeds over the ground.

Echo average is inoperable when a gyrocompass signal is not available. If you wish to use this feature without a gyrocompass signal, consult a FURUNO representative.

-1.28-

Manual speed entry is done at menu item 6 SHIP'S SPEED on the FUNCTIONS 2 menu which is accessed by pressing the RADAR MENU key.

CAUTION

Do not use the Echo Average function under heavy pitching and rolling loss of target detection can result.

1.24 Electronic Plotting Aid (EPA)

A maximum 10 operator-selected targets can be plotted electronically to assess their motion trend. Five past positions can be displayed for each of the plotted targets. If you enter a 6th plot on a certain target, the oldest plot (past position) will be erased.

A vector appears when you enter a second plot for the target and is updated each time a new plot is entered. The vector shows the target motion trend based on its latest two plots. The vector origin will move across the screen at a rate and direction defined by the calculated true course and speed until a next manual plotting.

Target data is shown in the data display area which shows: bearing, course, speed, CPA, TCPA, calculated true course of targets, calculated true speed of targets

Target 2 is on a collision course as the extension of the vector goes through the own ship position. Placing the offset EBL will be a help for assessment. TCPA is counted up to 99.9

min and beyond this it is indicated as TCPA > 99.9 MIN.

Note: EPA requires own ship's speed input (automatic or manual) and a heading signal. The

vector and data is updated automatically every 1-2 scenes between plot entries, but do not neglect to plot a new position over a long period of time. The accuracy will be reduced. Note the plots will be lost when the compass fails; start the plotting exercise again.

Plotting a target

To perform electronic plotting:

1. Place the cursor(+) on a target of interest by operating the trackball.

2. Press the ACQ key and one of numeric keys, and the plot symbol with number appears at the cursor position.

3. Watching the EPA time shown at the upper right margin of the screen, wait for at least 30 seconds. Place the cursor (+) on the target at its new location, press the ACQ key, and the same numeric key for the target.

The plot symbol moves to the new target position and previous position is marked by a small dot.

4. To acquire other targets, repeat the above steps selecting different plot number.

Note: If a target once plotted is not plotted again within 10 minutes, the warning "UPDATE

PLOT" will appear in red on the upper right margin of the screen and the plot symbol of the target flashes. If you want to continue plotting this target, reacquire it within 5 minutes.

Otherwise, the target will be regarded as a "lost target" and its plot symbol and target data will be erased. The larger the plotting interval, the less accurate the plotted target data. Plotting of each target should normally be made every 3 or 6 minutes as far as possible. You can use a

Watch Alarm to warn yourself every 3 or 6 min or whichever you may set.

Within 5 seconds, you can cancel a last plot by CANCEL key and make a re-entry at a different position. After 5 seconds, the last entry is processed to produce a vector.

True or relative vector

Vectors can be displayed relative to own ship's heading (Relative) or with reference to the north (True). Press the VECTOR key to select the required mode. This feature is available in all presentation modes (gyrocompass must be working correctly). The current vector mode is indicated at the upper-right corner of the screen.

Vector time

Vector time (or the length of vectors) can be set to 30 seconds, 1, 2, 3, 6, 12, 15 or 30 min and the selected vector time is indicated at the upper-right corner of the screen.

1. Press the PLOT MENU key, and [1] key several times until the desired vector time is reached.

Target data

The radar calculates motion trends (range, bearing, course, speed, CPA and TCPA) of all plotted targets.

In head-up and head-up true bearing modes, target bearing, course and speed shown in the upper-right target data field become true (T) relative to north or relative (R) relative to own ship in accordance with true/relative vector setting. In north-up, course-up, and True Motion modes, the target data field always displays true bearing, true course and speed over the ground.

Reading the target data

Press the ACQ key and corresponding numeric key, and the following target data is displayed.

RNG/BRG (Range/Bearing): Range and bearing from own ship to last-plotted target with

suffix "T" (True) or "R" (Relative) plot symbol.

CSE/SPD (Course/Speed): Course and speed are displayed for the last-plotted target with

suffix "T" (True) or :"R" (Relative) plot symbol.

CPA/TCPA: CPA (Closest Point of Approach) is a closest range the target will approach to

own ship. TCPA is the Time to CPA. Both CPA and TCPA are automatically calculated.

TCPA is counted up to 99.9 min and beyond this, it is indicated as TCPA > *99.9 MIN.

BCR/BCT: BCR (Bow Cross Range) is the range at which target will cross own ship's bow.

BCT (Bow Cross Time) is the estimated time at which target will cross own ship's bow. If

BCR is negative, BCR/BCT readout should be displayed as *.*.

Terminating target plotting

With EPA you can plot up to 10 targets. You may wish to terminate plotting of less important targets to newly plot other threatening targets.

By Symbol: To terminate plotting of a certain target, press the TARGET CANCEL key and

then press the corresponding plot number key.

With Trackball: Place the cursor (+) on a target which you do not want to be tracked any

longer by operating the trackball and press the TARGET CANCEL key.

All Targets: To terminate plotting of all targets at once, press and hold the TARGET

-1.31-

CANCEL key until all plot symbols and marks disappear in about 3 seconds.

Setting CPA/TCPA Alarm Ranges

When the predicted CPA of any target becomes smaller than a preset CPA alarm range and its predicted TCPA less than a preset TCPA alarm limit, the EPA releases an aural alarm and displays the warning label COLLISION on the screen. In addition, the EPA symbol changes to a triangle and flashes together with its vector.

Provided that this feature is used correctly, it will help prevent the risk of collision by alerting you to threatening targets. It is important that GAIN, A/C SEA, A/C RAIN and other radar controls are properly adjusted.

CPA/TCPA alarm ranges must be set up properly taking into consideration the size, tonnage, speed, turning performance and other characteristics of own ship.

CAUTION

CPA/TCPA

The CPA/TCPA alarm feature should never be relied upon as the sole means for detecting the risk of collision. The navigator is not relieved of the responsibility to keep visual lookout for avoiding collisions, whether or not the radar or other plotting aid is in use.

To set the CPA/TCPA alarm ranges:

1. Press the PLOT MENU key to show the EPA menu.

2. Press the [2] key to select COLLISION ALARM ON. At this point, a highlight cursor appears at the "CPA x.x NM" field.

3. Enter the CPA alarm range in nautical miles (0.0 to 9.9 nm) without omitting leading zeroes, if any, and press the ENTER key. The highlight cursor now moves to the "TCPA xx.x MIN" field.

4. Enter the TCPA alarm limit in minutes (1.0 to 99.9 min) without omitting leading zeroes, if any, and press the ENTER key.

5. Press the PLOT MENU key to close the menu.

Echo trails may be shown in monotone or gradual shading. Gradual shading paints the trails getting thinner with time just like the afterglow on an analog PPI radar.

(Monotone (SGL)) (Gradual shading (MULT))

- Press the [7] key to select menu item 7 TRAIL GRAD (graduation) in step 4, and

- Press the [7] key to select (or highlight) SGL (single tone) or MULT (multiple shading) option in step 5.

True or relative trails

You may display echo trails in true or relative motion (only true trail on TM). Relative trails show relative movements between targets and own ship. True motion trails require a gyrocompass signal and own ship speed input to cancel out own ship's movement and present true target movements in accordance with their over-the-ground speeds and courses.

(a) True target trails - no smearing of stationary targets

(b) Relative target trails - all targets moving relative to own ship

Note: When true trail is selected on the RM mode, the legend TRUE TRAIL appears in red.

No true-relative selection on TM, it is only True trails on TM mode.

To select true or relative echo trail presentation:

1. Press the RADAR MENU key to show the FUNCTIONS 1 menu.

2. Press the [0] key twice for FUNCTION 3 menu, then [2] key to show the RADAR 1 menu.

3. Press the [6] key to select menu item 6 TRAIL.

4. Press the [6] key to select (or highlight) REL (Relative) or TRUE option.

5. Press the ENTER key to confirm your selection; then RADAR MENU key to close the menu.

Each press of the [1] key within 5 seconds cyclically changes echo trail length (time) as below:

OFF - 30 s - 1 min - 3 min - 5 min - 15 min - 30 min - continuous - OFF

The current echo trail setting is displayed at the lower-right corner of the screen.

Suppose that "3 MIN" has just been selected. If the [1] key is hit on the FUNCTION 1 menu more than 5 seconds later, echo trails are removed from the display (memory still alive with echo trail timer count going on). Next hitting of the key calls out the echo trails on the screen.

To proceed to longer plot intervals, successively push the [1] key with a hit-and-release action.

The larger the echo trail length, the larger the echo trail plot interval.

Note: Holding the [1] key depressed for about 3 seconds on the FUNCTION 1 menu will

cause a loss of echo trail data so far stored in an memory.

Resetting echo trails

To reset (or clear) the echo trail memory, hold the TARGET TRAILS CANCEL key depressed for about 3 seconds. Echo trails are cleared and the trailing process restarts from time count zero at current echo trail plot interval. When memory assigned to echo trailing becomes the echo trail timer at the lower-right corner of the screen freezes and the oldest trails are erased to show the latest trails.

R/N/W versions: The TARGET TRAILS CANCEL key can be functioned as follows;

(a) Pressing the key within 3 seconds after the first press selects the trail time: 30 seconds, 1 min., and then 3 min.

(b) Pressing the key after more than 3 seconds from the first press tums off/on the trail display.

(c) Pressing the key for more than 2 seconds turns off the trail display with a beep. The trail memory is cleared. The next press for more than 2 seconds turns on the trail display and new trailing starts.

1.27 Parallel Index Lines

Parallel index lines are useful for keeping a constant distance between own ship and a coastline or a partner ship when navigating. Index lines are drawn in parallel with the No. 2

EBL (No. 2 EBL must be active). The orientation of the index lines is controlled with the

EBL control (without effecting the EBL indication) and the intervals between the lines adjusted with the VRM rotary control (provided that No. 2 VRM is active).

Maximum number of the index line can be set on INITIAL SETTING 3 menu: 2, 3 or 6.

1.33 Function Keys

The four function keys (#1-4) on the control head serve for a macro function to instantly select a combination of assigned functions or settings. The function keys provide optimum radar settings for a specific purpose with a single key operation.

Each function key can be assigned a combination of particular radar settings that will be most suited to your specific navigating purpose, and an adhesive label (such as BUOY, HARBOR,

COAST or the like) is usually attached to the key top for easy identification of the assigned purpose.

The individual function keys are preset, or programmed, for the following purposes by qualified service personnel at the time of installation using the procedures described in the succeeding paragraphs:

Function keys #1, #2 and #3: Picture setup and specific operation

Function key #4: Specific operation or watch alarm

1.33.1 Picture setup

Suppose that you have been navigating along a coast for hours and now you are approaching a harbor, your final destination. You will have to adjust your radar to change from the settings for coastal navigation to those for harbor approach. Every time your navigating environment or task changes, you must adjust the radar, which can be a nuisance in a busy situation.

Instead of changing radar settings case by case, it is possible to assign the function keys to provide optimum settings for often encountered situations.

The radar's internal computer offers several picture setup options to be assigned to each function key for your specific navigating requirements. For instance, one of the function keys may be assigned the buoy detecting function and labeled BUOY on the key top. If you press this key, the radar will be instantly set for optimum detection of navigation buoys and similar objects and the label BUOY is shown at the left margin of the screen. If you re-press the same key, the radar returns to the previous settings.

-1.46-

The picture setup options assignable to any of the function keys are shown in the table below:

LABEL DESCRIPTION

BUOY Optimum setting for detecting navigation buoys, small vessels and other small surface objects

SHORT

LABEL DESCRIPTION

SHIP

Optimum setting for short range LONG detection using a range scale of

3 nm or less on calm seas

Optimum setting for detecting vessels

Optimum setting for long range detection using a range scale of

6 nm or larger

CRUISING For cruising using a range scale of 1.5 nm or larger

COAST

ROUGH

SEA

For coastal navigation using a range of 12 nm or less

Optimum setting for rough weather or heavy rain

HARBOR Optimum setting for short range navigation in a harbor area using a range scale of 1.5 nm or less

SEA Transoceanic voyage using a range scale of 12 nm or larger

RIVER Optimum setting for navigation on a river

Each picture setup option defines a combination of several radar settings for achieving optimum setup for a particular navigating situation. Those involved are interference rejector, echo stretch, echo average, automatic anti-clutter, pulselength and noise rejector settings.

Adjusting these features on a function key menu changes the original function key settings.

To restore the original settings for a particular function key, it is necessary to display the relevant function key menu and select appropriate menu options.

Note: Function key presetting requires a good knowledge of optimum radar settings. If you

want to change the original function key settings, consult your nearest FURUNO representative or dealer.

1.33.2 Specific operation

Most often used controls are placed on the center panel while less often used controls are provided in the menu. To avoid opening the menus to set up the radar for a particular situation, function keys #1, #2, #3 and #4 may be assigned a combination of the following settings at the time of installation.

- Target trails (See paragraph 1.25.)

- Echo stretch 1,2 or 3 (See paragraph 1.22.)

- Pulselength 1 or 2 (See paragraph 1.11.)

- Echo averaging 1, 2 or 3 (See paragraph 1 .23.)

- Echo color (See paragraph 1.32.)

- Panel illumination

- Marks brilliance

- Noise rejection

Provided that the function key is assigned the specific operation feature, press the key to instantly set the radar for the preset purpose. The corresponding label will be displayed at the left margin of the screen. If you re-press the function key, the radar returns to the previous settings.

-1.47-

1.33.3 Watch alarm

The watch alarm sounds an external buzzer at selected time intervals to help you keep regular watch of the radar picture for safety or other purposes. This feature can be assigned to function key #4 with a choice of alarm intervals of 6, 10, 12, 15 and 20 minutes. (See the flowchart for keystroke sequence.)

Provided that function key #4 is assigned the watch alarm feature, just press function key #4 to activate the feature. The label WATCH appears at the lower-left corner of the screen associated with a watch alarm timer counts down from the initial value (e.g., "12:00").

When a preset time interval has elapsed, an audible watch alarm is released and the screen label WATCH turns red and the watch alarm timer freezes at "0:00."

To silence the alarm, press the AUDIO key. The label WATCH turns to normal color and the watch alarm timer is reset to the initial value and starts the count-down sequence again.

If you press the AUDIO OFF key before the selected time interval is reached, the watch alarm timer is reset to the initial value and starts the count-down sequence again.

1.35 Radar Map

A radar map is a combination of map lines and symbols whereby the user can define and input the navigation, route planning and monitoring data on the radar equipment. Map lines are navigational facility whereby the observer can define lines to indicate channels or traffic separation schemes. Also called nav lines, these lines can be ground stabilized to stop them drifting. (Definition in Annex C of IEC 60936-1 and IEC 60872-1)

In this series of radar, a radar map may contain 150 points of mark and line data on one map.

10 maps can the memorized to facilitate the repeated use on the routine navigation area.

The user can create a radar map on-real time base while using the radar for navigation or at leisure time at anchor or while the radar is not being used. Place of a map can be made for any waterways apart from the actual own ship location. The map data is stored on EEROM card which is mounted on the main processor board socket. When the optional Video Plotter board RP-26 and RAM card are installed in the display unit, much more data can be created and copied to another card.

General operation procedure:

1. Press the NAV MENU key to show the NAV INFORMATION 1 menu.

2. Press [2] key to select the SELECT NAVAID operation.

3. Press [2] key again to select navigation data input device, followed by the ENTER key.

4. Also, set other nav data parameters as appropriate referring to the operation flow shown on the next page.

5. Press the NAV MENU key to close the NAV INFORMATION menu.

Wind vector shows a direction from which the wind blows in, relative to own ship heading, and labeled T *. Wind velocity is a true wind speed as a result of compensating for own ship’s speed and orientation. Ocean current (tide) is the direction to which the current is flowing away from os position, relative to north.

* T in this case means a true value meanwhile T denotes “relative to True North” in the case of EBLs and target ship vectors.

Chapter 2 OPERATION OF ARPA (Option)

2.1 General

The FR-2105 series radar can accommodate an ARPA (Automatic Radar Plotting Aid) module ARP-26 complying with IMO A.823 and IEC 60987-1. This chapter describes the operation of the ARPA. For operation of normal radar, refer to Chapter 1.

Principal specifications

Acquisition and tracking

• Automatic acquisition of up to 20 targets plus manual acquisition of 10 targets, or fully manual acquisition of 30 targets between 0.2 and 32 nm. Manual acquisition has a priority over automatic acquisition. Therefore, if 20 targets have been manually acquired, the capacity for automatic acquisition is 10 targets.

• The ARPA automatically tracks all acquired targets, whether manually or automatically acquired, between 0.1 and 32 nm (0.1 and 24 nm depending on initial setting). Manually acquired targets are indicated in bold symbols and the automatically acquired targets, in thinner symbols.

Vector length: 0.5, 1, 2, 3, 6, 12, 15, 30 min.

Orientation: True velocity or relative velocity

Stabilization: Sea or Ground as selected with Vector key.

Motion trend: Displayed within 20 scans, full accuracy within 60 scans after acquisition.

Past positions: Choice of 5, 10 or 20 past positions at intervals of 30 s, 1, 2, 3 or 6 min.

Alarms: Visual and audible alarms against targets violating CPA/TCPA limits, lost targets, targets crossing guard zone, system failure and target full status.

Trial maneuver: Predicted situation appears in 1 min after selected delay (1-60 minutes).

2 .

2.2 Keypads for ARPA

The ARPA uses the keys on the plotting keyboard on the right side of the radar screen and two keys on the control head.

PLOT MENU: Shows/hides ARPA menus.

Plot Symbol keys: Select specific plot symbols for

manually acquired targets.

TARGET CANCEL: Terminates tracking of a

single target specified by the trackball if the key is pressed with a hit-and-release action. If the key is held depressed for about 3 seconds, tracking of all targets is terminated.

3. Press the [6] key to select (or highlight) LOG option.

2 .

4. Press the ENTER key to conclude your selection followed by the RADAR MENU key to close the FUNCTIONS 2 menu. The ship's speed readout at the top of the screen shows own ship's speed fed from the speed log preceded by the label "LOG."

Notes:

1) IMO Resolution A.823(19) for ARPA recommends that a speed log to be interfaced with an ARPA should be capable of providing through-the-water speed data (forward speed).

2) Be sure not to select LOG when a speed log is not connected. If the log signal is not provided, the ship speed readout at the top of the screen will be blank. In the event of a log error, you can continue plotting by entering a manual speed.

3) If a log signal interval becomes more than 30 seconds with the ship's speed 5 kt or more, the radar regards the speed log is defective and LOG FAIL appears, reading xx.x KT. If no speed input is present for 3 minutes at below 0.1 kt, the radar regards the log is defective.

Manual speed input

To manually enter the ship's speed with the numeric keys:

1. Press the RADAR MENU key and [0] key to show the FUNCTIONS 2 menu.

2. Press the key [6] to select menu item SHIP'S SPEED.

3. Press the key [6] to select (or highlight) MAN option.

4. Press the ENTER key to conclude your selection. At this point, "MAN = xx.x KT" appears at the bottom of the FUNCTIONS 2 menu.

5. Enter the ship speed by hitting corresponding numeric keys followed by the ENTER key without omitting leading zeroes, if any. As an example, if the ship speed is 8 knots, press

[0] [8] [ENTER]. For 4.5 knots, [0] [4] [5] [ENTER].

6. Press the RADAR MENU key to close the FUNCTIONS 2 menu. The ship speed readout at the screen top shows own ship's speed you entered preceded by the label "MENU."

Target-based speed

The use of target-based speed is recommended when:

• The speed log is not operating properly or not connected to the radar.

• The vessel has no device which can measure ship's leeward movement (Doppler sonar, speed log, etc.) when leeward movement can not be disregarded.

If you select target-based speed, the ARP-26 calculates own ship's speed relative to a fixed reference target. The number of targets may be 1, 2 or 3. They appear as tracked targets, each shown in a small circle, but without a vector. When a plural of objects are selected, the mean value is used for stabilization and speed. Select the number in [PLOT MENU], see section

2.3.

1. Select a small fixed island or any radar prominent point located at 0.2 to 24 nm from own ship.

2. Place the cursor (+) on the target by operating the trackball.

2 .

3. Press the PLOT MENU key and [6] key followed by the ENTER key.

The reference target mark (see below) appears at the cursor position and the own ship data label changes from "LOG," "NAV" or "MENU" to "REF." Note that it takes 60 scans or approximately 1 min before a new speed is displayed. If tracking has failed for a reference target, the target is marked with a lost target mark (symbol formed with two triangles).

R changes to

○

R in 60 scans

Notes:

1) When the reference target is lost or goes out of the acquisition range, the reference target mark blinks and the speed reads "xx.x." Select a different reference target in this case.

2) When all targets are deleted, the reference target mark is also deleted and the target-based speed becomes invalid. The speed is indicated in KTBT where BT means Bottom Track

(speed over ground).

3) The vector of the reference target can be displayed by menu operation (ARPA 1 menu).

Canceling target-based speed

To cancel the target-based speed, the PLOT MENU and [6] key. The speed is shown by LOG,

NAV* or MANUAL as selected previously.

Deactivating the ARPA

To deactivate the ARPA, press the RADAR MENU key and [8] key twice followed by the

ENTER key. Target plotting symbols and the on-screen label ARPA will disappear. The label

EPA appears.

The ARPA can acquire up to 30 targets (20 automatically and 10 manually or all 30 manually).

If AUTO ACQ is selected after more than 20 targets have been manually acquired, only the remaining capacity of targets can be automatically acquired. For example, when 30 targets have been acquired manually, then the ARPA is switched to AUTO ACQ. Only 10 targets can be acquired automatically.

A target just acquired automatically is marked with a broken square and a vector appears within 20 scans of antenna to indicate the target's motion trend. Within 60 scans, the initial tracking stage is finished and the target becomes ready for stable tracking. At this point, the broken square mark changes to a solid circle. (Targets automatically acquired are distinguished from those acquired manually, the targets which are acquired manually are displayed by bold symbol.)

TARGET CANCEL key.

Canceling all targets at a time

Press and hold the TARGET CANCEL key down more than 3 seconds. In the automatic acquisition mode, acquisition begins again.

Discrimination between landmass and true targets

A target is recognized as a landmass and thus not acquired if it is 800 m or more in range or bearing direction.

2 .

In auto acquisition mode (AUTO ACQ ON), up to 20 targets can be manually acquired in addition to 20 auto acquired targets. When auto acquisition is disabled (AUTO ACQ OFF), up to 40 targets can be manually acquired and automatically tracked.

To manually acquire a target:

1. Place the cursor (+) on a target of interest by operating the trackball.

2. Press the ACQ key on the control head. The selected plot symbol is marked at the cursor position.

Note that the plot symbol is drawn by broken lines during the initial tracking stage. A vector appears in about one minute after acquisition indicating the target's motion trend. If the target is consistently detected for three minutes, the plot symbol changes to a solid mark. If acquisition fails, the target plot symbol blinks and disappears shortly.

(a) Immediately after acquisition, this plot symbol is shown in broken lines.

(b) Within 20 scans of antenna after acquisition, a vector appears to show a trend of movement.

(c) Within 60 scans of antenna after acquisition, the plot symbol changes to a small circle indicating steady-state tracking condition.

Notes:

1) For successful acquisition, the target to be acquired should be within 0.2 to 32 nm from own ship and not obscured by sea or rain clutter.

2) When you have acquired 40 targets manually, the message MAN TARGET FULL is displayed at the screen bottom. Cancel tracking of non-threatening targets if you wish to acquire additional targets manually. (See "Terminating tracking of acquired targets" on page 2-9.)

2.9 Displaying Target Data

The ARPA mode (with built-in ARP-26 optional board) provides the full functionality of

ARPA as required by the IMO Resolution A.823(19) and IEC 60972-1, including display of range, bearing, course, speed, CPA and TCPA of all plotted targets. Data on 3 targets may be displayed on the text area at a time.

In head-up and head-up true bearing modes, target bearing, course and speed shown in the upper-right target data field become true (suffix "T") or relative (suffix "R") to own ship in accordance with the true/relative vector setting. In north-up, course-up and true motion modes, the target data field always displays true bearing, true course and speed over the ground.

Place the cursor on a desired target and press the [TARGET DATA] key. Target data display is as below.

RNG/BRG (Range/Bearing): Range and bearing from own ship to the selected target with

suffix "T" (True) or "R" (Relative).

CSE/SPD (Course/Speed): Course and speed are displayed for the selected target with suffix

"T" (True) or "R" (relative).

CPA/TCPA: CPA(Closest Point of Approach) is the closest range a target will approach to

own ship. TCPA is the time to CPA. Both CPA and TCPA are automatically calculated.

When the CPA has passed clear of own ship, it is indicated by a TCPA with a negative (-) sign. TCPA is counted to 99.9 min and beyond this, it is indicate as TCPA> -99.9MIN.

2.10 Vector modes

Target vectors can be displayed relative to own ship's heading (Relative) or north (True).

Ground stabilization and Sea Stabilization

Target vectors can be ground stabilized or sea stabilized. Sea stabilization is a mode where own ship and all targets are referenced to the sea using gyro heading and single axis log water speed inputs in True Motion mode. Ground stabilization is a mode where own ship and all targets are referenced to the ground using the ground track or set and drift inputs. If the accuracy seems unsatisfactory, enter the set and drift correction (section 2.12).

True vector

Vector mode, True or Relative, is selected with the VECTOR key. With true vectors the radar display will look like the one shown below.

In the true motion mode, all fixed targets such as land, navigational marks and ships at anchor remain stationary on the radar screen with vector length zero. But in the presence of wind and/or current, vectors appear on fixed targets representing the reciprocal of set and drift affecting own ship unless set and drift values are properly entered.

Relative vectors on targets which are not moving over the ground such as land, navigational marks and ships at anchor will represent the reciprocal of own ship’s ground track. A target of which vector extension passes through own ship is on the collision course. (Dotted lines in the figure are for explanation only.)

Vector time

Vector time (or the length of vectors) can be set to 30 seconds, 1, 2, 3, 6, 12, 15 or 30 minutes and the selected vector time is indicated at the upper-right corner of the screen.

1. Press the PLOT MENU key to display the ARPA 1 menu.

2. Press the [1] key to select the VECTOR TIME option.

3. Further press the [1] key to select (or highlight) a desired vector time.

4. Press the ENTER key to conclude your selection.

5. Press the PLOT MENU key to close the menu.

The vector tip shows an estimated position of the target after the selected vector time elapses.

It can be valuable to extend the vector length to evaluate the risk of collision with any target.

R/N/W version: ARPA vector time can be programmed onto the function key. (e.g. pressing the function key can change the vector time.)

2.11 Past Position Display

The ARPA displays equally time-spaced dots marking the past positions of any targets being tracked.

A new dot is added every minute (or at preset time intervals) until the preset number is reached.

If a target changes its speed, the spacing will be uneven. If it changes the course, its plotted course will not be a straight line.

2.12 Set and Drift (Set and Rate)

Set, the direction in which a water current flows, can be manually entered in 0.1-degree steps.

Drift, in another word Rate, the speed of tide, can also be entered manually in 0.1 knot steps.

2 .

17-

Set and drift corrections are beneficial for increasing the accuracy of vectors and target data.

The correction is best made in the head-up mode with true vectors, watching landmasses, or other stationary targets. Thus, the speed and course of own ship over the ground are reciprocally calculated and compared with the relative bearing and range to the reference target to produce a Set and Drift. These values are automatically applied to all targets. If stationary targets have vectors, set and drift values should be adjusted until they lose vectors.

Proceed as follows to enter set and drift (rate):

1. Press the RADAR MENU key to show the FUNCTIONS 1 menu.

2. Press the [0] key to show the FUNCTIONS 2 menu.

3. Press the [7] key to select menu item SET, DRIFT.

4. Further press the [7] key to select OFF or MAN option.

OFF: No correction against set and drift.

MAN: Manual entry of set and drift data.

5. If OFF is selected, press the ENTER key.

6. If you have selected MAN in step 4 above, the highlight cursor will advance to right requesting you to enter SET xxx.x°. Enter the value of set in degrees by hitting numeric keys without omitting leading zeroes, if any, and press the ENTER key.

The highlight cursor will then advance to the next line DRIFT xx.xKT. Enter the value of drift in knots by hitting numeric keys without omitting leading zeroes, if any, and press the

ENTER key. Set and drift have the same effect on own ship and all targets.

7. Press the RADAR MENU key to close the menu. The label LOG (or NAV) on the top of the display changes to SMG xx.x KTBT, where SMG stands for Speed Made Good and BT,

Bottom Track. Set and drift data can also be used in the basic radar without ARPA function.

2.13 Setting CPA/TCPA Alarm Ranges

The ARPA continuously monitors the predicted range at the Closest Point of Approach (CPA) and predicted time to CPA (TCPA) of each tracked target to own ship.

When the predicted CPA of any target becomes smaller than a preset CPA alarm range and its predicted TCPA less than a preset TCPA alarm limit, the ARPA releases an aural alarm and displays the warning label COLLISION on the screen. In addition, the ARPA symbol changes to a triangle and flashes together with its vector.

CPA/TCPA alarm ranges must be set up properly taking into consideration the size, tonnage, speed, turning performance and other characteristics of own ship.

2.15 Operational Warnings

There are six main situations which cause the ARPA to trigger visual and aural alarms:

• CPA/TCPA alarm

• Guard zone alarm

• Lost target alarm

• Target full alarm for manual acquisition

• Target full alarm for automatic acquisition

• System failures

CPA/TCPA alarm

Visual and aural alarms are generated when the predicted CPA and TCPA of any target become less than their preset limits. Press the AUDIO OFF key to acknowledge and silence the CPA/TCPA aural alarm.

21-

Guard zone alarm

Visual and aural alarms are generated when a target transits the operator-set guard zone. Press the AUDIO OFF key to acknowledge and silence the guard zone aural alarm. (Refer to paragraph 2.14 Setting a Guard Zone for further information.)

Lost target alarm

When the system detects a loss of a tracked target, the target symbol becomes a flashing diamond ( ) and the label "LOST" appears at the screen bottom. At the same time, an aural alarm is produced for one second.

Press the LOST TARGET key to acknowledge the lost target alarm. Then, the lost target mark disappears.

Target full alarm

When the memory becomes full, the memory full status is indicated and the relevant indication appears on the screen and a short beep sounds.

Manually acquired targets

The indication "MAN TARGET FULL" appears at the screen bottom and a short beep tone sounds when the number of manually acquired targets reaches 20 or 40 depending on whether auto acquisition is activated or not.

Automatically acquired targets

The indication "AUTO TARGET FULL" appears at the screen bottom and a short beep tone sounds when the number of automatically acquired targets reaches 20.

System failure alarm

When the ARP board receives no signal input from the radar or external equipment, the screen shows both "SYSTEM FAIL" associated with an indication denoting offending equipment, also releasing an aural alarm. The missing signals are denoted as shown below:

2.16 Trial Maneuver

Trial simulates the effect on all tracked targets against own ship's maneuver without interrupting the updating of target information.

There are two types of trial maneuvers: static and dynamic.

Dynamic trial maneuver

A dynamic trial maneuver displays predicted positions of the tracked targets and own ship.

You enter own ship's intended speed and course with a certain "delay time." Assuming that all tracked targets maintain their present speeds and courses, the targets' and own ship's future movements are simulated in one-second increments indicating their predicted positions in one-minute intervals as illustrated below.

The delay time represents the time lag from the present time to the time when own ship will actually start to change her speed and/or course. You should therefore take into consideration own ship's maneuvering characteristics such as rudder delay, turning delay and acceleration delay. This is particularly important on large vessels. How much the delay is set the situation starts immediately and ends in a minute.

In the example shown below, own ship will advance straight ahead (even after a maneuver) for a delay time of 5 minutes and then alters speed and course until operator-specified intended speed and course are achieved (position OS7 in this example).

Note that once a dynamic trial maneuver is initiated, you cannot alter own ship's trial speed, course or delay time until the trial maneuver is terminated.

2 .

Static trial maneuver

A static trial maneuver displays only the final situation of the simulation. If you enter the same trial speed, course and delay time under the same situation as in the aforementioned example of dynamic trial maneuver, the screen will instantly show position OS7 for own ship, position

A7 for target A and position B7 for target B, omitting the intermediate positions. Thus, the static trial maneuver will be convenient when you wish to know the maneuver result immediately.

Note: For accurate simulation of ship movements in a trial maneuver, own ship's characteristics such as acceleration and turning performance should be properly set in initial settings at the time of installation.

2.18 Criteria for Selecting Targets for Tracking

The FURUNO ARPA video processor detects targets in midst of noise and discriminates radar echoes on the basis of their size. Target whose echo measurements are greater than those of the largest ship in range or tangential extent are usually land and are displayed only as normal radar video. All smaller ship-sized echoes which are less than this dimension are further analyzed and regarded as ships and displayed as small circles superimposed over the video echo.

When a target is first displayed, it is shown as having zero true speed but develops a course vector as more information is collected. In accordance with the International Marine

Organization Automatic Radar Plotting Aid (IMO ARPA) requirements, an indication of the motion trend should be available within 20 scans of antenna and full vector accuracy within

60 scans. The FURUNO ARPAs comply with these requirements.

Acquisition and tracking

A target which is hit by 5 consecutive radar pulses is detected as a radar echo. Manual acquisition is done by designating a detected echo with the trackball. Automatic acquisition is done in the acquisition areas when a target is detected 5-7 times continuously depending upon the congestion. Tracking is achieved when the target is clearly distinguishable on the display for 5 out of 10 consecutive scans whether acquired automatically or manually. Required tracking facilities are available within 0.1-32 nm on range scales including 3, 6, 12 nm, full plotting information is available within one scan when the range scale has been changed.

Targets not detected in 5 consecutive scans become "lost targets."

Quantization

The entire picture is converted to a digital from called "Quantified Video." A sweep range is divided into small segments and each range element is "1" if there is radar echo return above a threshold level, or "0" if there is no return.

2 .

26-

The digital radar signal is then analyzed by a ship-sized echo discriminator. As the antenna scans, if there are 5 consecutive radar pulses with 1’s indicating an echo presence at the exact same range, a target "start" is initiated. Since receiver noise is random, it is not three bang correlated, and it is filtered out and not classified as an echo.

The same is true of radar interference. Electronic circuits track both the closet and most distant edges of the echo. At the end of the scanning of the echo, the discriminator indicates the measured maximum range extent and total angular extent subtended by the echo. If the echo is larger than a ship-sized echo in range extent and/or angular width, adjusted as a function of range, it is declared to be a coastline and the closet edge is put into memory as a map of the area. This land outline is used to inhibit further acquisition and tracking of ship sized echoes beyond the closest coast outline. 5 consecutive scans of coastal outline are retained in memory to allow for signal variation. All smaller echoes are declared to be ship sized and the middle of the leading edge is used to provide precise range and bearing coordinates of each echo on every scan. This range/bearing data is matched to previous data and analyzed from scan-to-scan for consistency. When it is determined to be as consistent as a real target, automatic acquisition occurs and tracking is initiated. Continued tracking and subsequent calculation develop the relative course and speed of the target just as a man would do when plotting the relative course and speed of the target on the scope with a grease pencil.

The true course and speed of own ship are computed from own ship's gyro and speed inputs, and the resulting course and speed of each tracked target is easily computed by vector summing of the relative motion with own ship’s course and speed. The resulting true or relative vector is displayed for each of the tracked targets. This process is updated continually for each target on every scan of the radar.

Automatic acquisition areas and suppression lines

Performance of auto-acquisition is enhanced by controlling the limit lines (suppression line) in the former series of FURUNO ARPAs. In this new series of ARPAs, the automatic acquisition rings are used instead of the limit lines.

Auto acquisition rings work as suppression lines when viewed from the opposite direction.

They should be placed clear of a landmass or shoreline. The acquisition areas may be a full

360 degree circle or sector of any angles are gyro stabilize.

Qualitative description of tracking error

The FURUNO ARPA accuracy complies with or exceed IMO standards.

Own ship maneuvers

For slow turns there is no effect. For very high turning rates (greater than 150°/ minute, depending on gyro), there is some influence on all tracked targets which last for a minute or two and then all tracked targets revert to full accuracy.

Other ship maneuvers

Target ship courses, lag 15 to 30 seconds at high relative speed, or 3 to 6 seconds at low (near

0) relative speed. It is less accurate during a turn due to lag, but accuracy recovers quickly.

2.19 Factors Affecting ARPA Functions

Sea returns

If the radar anti-clutter control is adjusted properly, there is no serious effect because distant wave clutter, not eliminated by this control, is filtered out by more than one bang correlation and scan-to-scan matching of data.

Rain and snow

Clutter can be acquired and tracked as targets. Adjust the A/C RAIN control. If it is heavy rain, switch to S-band if provided, or switch on the interference rejector on the radar. If heavy clutter still exists, switch to manual acquisition. Accuracy can be affected.

Low clouds

Usually no effect. If necessary, adjust the A/C RAIN control.

Non-synchronous emissions

No effect.

Low gain

Insufficient or low radar receiver gain will result in some targets not being acquired at long distance. ARPA display will be missing on one or more targets that could only be visible if the radar sensitivity control (GAIN control) were increased.

The setting of the correct radar receiver gain is not critical but the target should be on the radar

PPI and be clearly visible and well defined.

Manual acquisition is done if a target is positively displayed more than once. Automatic acquisition is done when the target is detected 5-7 times continuously. Tracking is achieved when the target is detected 5 times (not necessarily continuously) out of 10 scans. If not detected 6 times out of 10 scans, the target will become a "lost target." The ARPA will acquire a radar echo that is present once in every six antenna scans and continue tracking if 1 in 10.

Second trace echoes

When the radar beam is super refracted, strong echoes may be received at such long ranges that they appear on a different timebase sweep than the transmitted pulse. This gives an incorrect range indication. Second and third trace echoes can be tracked if they are consistent enough to meet acquisition and tracking criteria but target course and speed data will be in error.

2 .

28-

Blind and shadow sectors

Radar shadow or blind areas caused by obstructions aboard ship, for example, funnels and masts, in the path of the radar beam can result in reduction of radar beam intensity in that particular direction. This may eliminate the detection of some targets. The ARPA system will lose track of targets shortly after they are lost on the radar picture and if they remain in a blind zone. These targets will however be acquired and tracked when they pass out of the blind zone and again present normal radar echo. The angular width and bearing of any shadow sector should be determined for their influence on the radar. In certain cases false echoes in the shadow sector cause the ARPA system to acquire, track, and vector them. Shadow sectors should be avoided.

Indirect echoes

A target at close range is usually picked up directly, but it can also be received as reflection from a large, flat surface. This will result in the radar presenting two or more echoes on the display, each at a different range. The ARPA can acquire and track the false echo if it is detected by five consecutive scans. Reduction in radar GAIN can eliminate the multiple echoing but care should be taken as range detection also will be reduced.

Radar interference

If interference is extreme due to another radar operating at close range, spiral "dotting" and/or false targets may appear momentarily. The interference rejector can clear the display.

To receive radar beacon or SART signals, turn off the radar interference rejection and echo average which operate on the correlation technique.

Chapter 3 RADAR OBSERVATION

3.1 General

Minimum and maximum ranges

Minimum range

The minimum range is defined by the shortest distance at which, using a scale of 1.5 or 0.75 nm, a target having an echoing area of 10 m 2 is still shown separate from the point representing the antenna position.

It is mainly dependent on the pulselength, antenna height, and signal processing such as main bang suppression and digital quantization. It is a good practice to use a shorter range scale as far as it gives favorable definition or clarity of picture. The IMO Resolution MSC.64(67)

Annex 4 (Shipborne radar) and A.820: 1995 (High Speed Craft Radar) require the minimum range to be less than 50 m and 35 m, respectively. This series of radars satisfy this requirement.

Maximum range

The maximum detecting range of the radar, Rmax, varies considerably depending on several factors such as the height of the antenna above the waterline, the height of the target above the sea, the size, shape and material of the target, and the atmospheric conditions.

Under normal atmospheric conditions, the maximum range is equal to the radar horizon or a little shorter. The radar horizon is longer than the optical one by about 6% because of the diffraction property of the radar signal. The Rmax is given in the following equation.

R max

= 2.2 x ( h1 + h2 ) where Rmax: h1: radar horizon (nautical miles)

antenna height (m) h2 : target height (m)

Radar horizon

Optical horizon

For example, if the height of the antenna above the waterline is 9 meters and the height of the target is 16 meters, the maximum radar range is;

R max

= 2.2 x ( 9 + 16 ) = 2.2 x (3 + 4) = 15.4 nm

It should be noted that the detection range is reduced by precipitation (which absorbs the radar signal).

-3.1-

X-band and S-band

In fair weather, the above equation does not give a significant difference between X- and

S-band radars. However, in heavy precipitation condition, an S-band radar would have better detection than an X-band radar.

Radar resolution

There are two important factors in radar resolution (discrimination): bearing resolution and range resolution.

Bearing resolution

Bearing resolution is the ability of the radar to display as separate pips the echoes received from two targets which are at the same range and close together. It is proportional to the antenna length and reciprocally proportional to the wavelength. The length of the antenna radiator should be chosen for a bearing resolution better than 2.5° (IMO Resolution). This condition is normally satisfied with a radiator of 1.2 m (4 ft) or longer in the X-band. The

S-band radar requires a radiator of about 12 feet (3.6 m) or longer.

Range resolution

Range resolution is the ability to display as separate pips the echoes received from two targets which are on the same bearing and close to each other. This is determined by pulselength only.

Practically, a 0.08 microsecond pulse offers the discrimination better than 35 m as do so with all FURUNO radars.

Test targets for determining the range and bearing resolution are radar reflectors having an echoing area of 10 m

Bearing accuracy

One of the most important features of the radar is how accurately the bearing of a target can be measured. The accuracy of bearing measurement basically depends on the narrowness of the radar beam. However, the bearing is usually taken relative to the ship’s heading, and thus, proper adjustment of the heading marker at installation is an important factor in ensuring bearing accuracy. To minimize error when measuring the bearing of a target, put the target echo at the extreme position on the screen by selecting a suitable range.

Range measurement

Measurement of the range to a target is also a very important function of the radar. Generally, there are two means of measuring range: the fixed range rings and the variable range marker

(VRM). The fixed range rings appear on the screen with a predetermined interval and provide a rough estimate of the range to a target. The variable range marker’s diameter is increased or decreased so that the marker touches the inner edge of the target, allowing the operator to obtain more accurate range measurements.

-3.2-

Occasionally echo signals appear on the screen at positions where there is no target or disappear even if there are targets. They are, however, recognized if you understand the reason why they are displayed. Typical false echoes are shown below.

Multiple echoes

Multiple echoes occur when a transmitted pulse returns from a solid object like a large ship, bridge, or breakwater. A second, a third or more echoes may be observed on the display at double, triple or other multiples of the actual range of the target as shown below. Multiple reflection echoes can be reduced and often removed by decreasing the gain (sensitivity) or properly adjusting the A/C SEA control.

Sidelobe echoes

Every time the radar pulse is transmitted, some radiation escapes on each side of the beam, called "sidelobes." If a target exists where it can be detected by the side lobes as well as the main lobe, the side echoes may be represented on both sides of the true echo at the same range.

Side lobes show usually only on short ranges and from strong targets. They can be reduced through careful reduction of the gain or proper adjustment of the A/C SEA control.

Virtual image

A relatively large target close to your ship may be represented at two positions on the screen.

One of them is the true echo directly reflected by the target and the other is a false echo which is caused by the mirror effect of a large object on or close to your ship as shown in the figure below. If your ship comes close to a large metal bridge, for example, such a false echo may temporarily be seen on the screen.

-3.3-

Shadow sectors (see above right)

Funnels, stacks, masts, or derricks in the path of the antenna block the radar beam. If the angle subtended at the scanner is more than a few degrees, a non-detecting sector may be produced.

Within this sector targets can not be detected.

3.3 SART (Search and Rescue Transponder)

A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 nm. Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band. When interrogated, it first sweeps rapidly (0.4 µs) through the band before beginning a relatively slow sweep (7.5 µs) through the band back to the starting frequency. This process is repeated for a total of twelve complete cycles. At some point in each sweep, the SART frequency will match that of the interrogating radar and be within the pass band of the radar receiver. If the

SART is within range, the frequency match during each of the 12 slow sweeps will produce a response on the radar display, thus a line of 12 dots equally spaced by about 0.64 nautical miles will be shown.

When the radar to the SART is reduced to about 1 nm, the radar display my show also the 12 responses generated during the fast sweeps. These additional dot responses, which also are equally spaced by 0.64 nautical miles, will be interspersed with the original line of 12 dots.

They will appear slightly weaker and smaller than the original dots.

Showing SART marks on the radar display

To show the SART marks only on the radar display, detune the radar receiver by turning the

TUNE control out of best tuning condition. This erases or weakens all normal radar echoes, but, the SART marks are not erased because the SART response signal scans over all frequencies in the 9 GHz band. When the radar approaches the SART in operation, the SART marks will enlarge to large arcs, blurring a large part of the screen. Reduce the sensitivity and adjust the sea clutter control of the radar.

-3.4-

Summary to detect SART response

1. Use range scale of 6 or 12 nm as the spacing between the SART responses is about 0.6 nm

(1125 m) to distinguish the SART.

2. Turn off the automatic clutter suppression.

3. Turn off the Interference Rejector.

4. Turn off the Echo Average.

General remarks on receiving SART

Radar range scale

When looking for a SART it is preferable to use either the 6 or 12 nautical mile range scale.

This is because the total displayed length of the SART response of 12 (or 24) dots may extend approximately 9.5 nautical miles beyond the position of the SART and it is necessary to see a number of response dots to distinguish the SART from other responses.

SART range errors

When responses from only the 12 low frequency sweeps are visible (when the SART is at a range greater than about 1 nm), the position at which the first dot is displayed may be as mush as 0.64 nm beyond the true position of the SART. When the range closes so that the fast sweep responses are seen also, the first of these will be no more than 150 meters beyond the true position.

Radar bandwidth

This is normally matched to the radar pulselength and is usually switched with the range scale and the associated pulselength. Narrow bandwidths of 3-5 MHz are used with long pulses on long range scales and wide bandwidths of 10-25 MHz with short pulses on short ranges.

A radar bandwidth of less than 5 MHz will attenuate the SART signal slightly, so it is preferable to use a medium bandwidth to ensure optimum detection of the SART.

Radar side lobes

As the SART is approached, side lobes from the radar antenna may show the SART responses as a series of arcs or concentric rings. These can be removed by the use of the anti-clutter sea control although it may be operationally useful to observe the side lobes as they may be easier to detect in clutter conditions and also they will confirm that the SART is near to own ship.

-3.5-

Detuning the radar

To increase the visibility of the SART in clutter conditions, the radar may be detuned to reduce the clutter without reducing the SART response. Radar with automatic frequency control may not permit manual detune of the equipment. Care should be taken in operating the radar in the detuned condition as other wanted navigational and anti-collision information may be removed. The tuning should be returned to normal operation as soon as possible.

Gain

For maximum range SART detection the normal gain setting for long range detection should be used, i. e., with a light background noise speckle visible.

A/C SEA control

For optimum range SART detection, this control should be set to the minimum. Care should be exercised as wanted targets in sea clutter may be obscured. Note also that in clutter conditions the first few dots of the SART response may not be detectable, irrespective of the setting of the anti-clutter sea control. In this case, the position of the SART may be estimated by measuring 9.5 nautical miles from the furthest dot back towards own ship.

Some sets have automatic/manual anti-clutter sea control facilities in which case the operator is advised to use manual control initially until the SART has been detected. The effect of the auto sea control on the SART response can then be compared with manual control.

A/C RAIN control

This should be used normally (i.e. to break up areas of rain) when trying to detect a SART response which, being a series of dots, is not affected by the action of the anti-clutter rain circuitry. Note that Racon responses, which are often in the form of a long flash, will be affected by the use of this control.

Some sets have automatic/manual anti-clutter rain control facilities in which case the operator is advised to use manual control initially until the SART has been detected. The effect of the auto sea control on the SART response can then be compared with manual control.

This information is excerpted from IMO SN/Circ 197 OPERATION OF MARINE RADAR FOR SART

DETECTION.

3.4 RACON (Radar beacon)

A RACON is a radar beacon which emits radar receivable signals in the radar frequency spectrum (X or S band). There are several signal formats; in general, the Recon signal appears on the radar screen as a rectangular echo originating at a point just beyond the position of the radar beacon. It has a Morse coded pattern. Note that the position on the radar display is not accurate.

CHAPTER 4 OPERATION OF VIDEO PLOTTER

4.1 General

The Video Plotter RP-26 is an optional circuit board which is accommodated in the display unit of the radar. It permits use of 2 memory cards, a memory card(RAM) for storing the operator created radar maps, and the other is a chart card(ROM) storing Furuno made digital charts.

The memory card enables the operator to create radar maps more precisely than the standard supplied radar map card (150 points per map). 30 navigation lines may be stored and each line may contain up to 30 vertexes (waypoints). Five nav lines may be simultaneously shown on the display. 98 waypoints, numbered 1-98, may be stored. The card permanently retains the data you have entered from the radar display or by Lat/Long positions. Own ship and other ship tracks may be stored at a selected interval. To display Nav line, RTE and WPL sentences are necessary. WPL ID sentence received in figure only. The data can be copied for other ships of the same shipping company.

Charts are superimposed on the radar picture without disturbing the radar observation. The chart area is dependent on the radar range in use.

The drive for the ROM card can also drive the Electronic Reference Chart (ERC). The ERC is a digital chart published by the Japanese Hydrographic Bureau. Note it is not an ENC used for

ECDIS.

Track Plotting Interval

The memory stores ship's position in latitude and longitude at a sampling rate set on the OWN

SHIP, TARGET PLOT menu. The position data so stored is used to display past own ship's track on the screen.

The plotting interval affects track reconstruction. A shorter interval provides more accurate reconstruction of track, however storage time of the track is reduced.

1. Press [NAV MENU] and [5] in order.

2. To change own ship's track plotting interval, press [3] several times to display desired plotting interval in reverse video.

3. Press [ENTER].

4. To change ship's track plotting interval, press [6] (several times) to select plotting interval.

5. Press [ENTER].

Plot interval and track storage time

Memory capacity for own ship's track and other ship's track is 6,000 points each. For other ship's track the 6,000 points is divided equally among ten targets, so there are 600 points per target. When a track memory becomes full the oldest track is deleted to make room for a new entry.

-4.6-

If own ship track is stored every minute, 6,000 points of memory represents 100 hours of time span; 3 min intervals covers 16 days and 16 h. The time span covering one other ship is 1/10 of own ship as a total of 10 other ships equal to one OS.

Memory used

Press [NAV MENU] and [0]. Memory used appears as below:

MEMORY IN USE

OWN SHIP = 3456

Smoothing

Even when the vessel is sailing in a straight line the track shown on the display looks irregular.

This is due to signal variation of the external navaid. You can compensate for this irregularity with smoothing.

A smoothing factor between 1 and 9 is available. OFF provides no smoothing. In most cases a smoothing setting between 1 and 5 is satisfactory.

1. Press [NAV MENU] and [5] in order.

2. Press [8] to select smoothing factor.

4.11 Latitude Error Table (on 96 nm range scale)

The longitude lines concentrate on the north pole and south pole, namely, 1 nm is equivalent to 1 minute at 0 degree latitude, 2 minutes at 60 degrees latitude, 3 minutes at 70 degrees latitude and so on. For this reason, a longitude error occurs on the radar display. For example, when own ship is at 60

N and 135

E, even if the cursor indication is 62

N and 139

E, the real cursor position is deviated to left (west) side. The table below shows the longitude error, represented from 0

to 90

Chapter 5 MAINTENANCE

WARNING

Do not open the equipment.

Hazardous voltage which can cause electrical shock exists inside the equipment. Only qualified personnel should work inside the equipment.

Turn off the radar power switch before servicing the antenna unit. Post a warning sign near the switch indicating it should not be turned on while the antenna unit is being serviced.

Prevent the potential risk of being struck by the rotating antenna and exposure to

RF radiation hazard.

Wear a safety belt and hard hat when working on the antenna unit.

Serious injury or death can result if someone falls from the radar antenna mast.

Periodic checks and maintenance are important for proper operation of any electronic systems.

This chapter contains maintenance instructions to be followed to obtain optimum performance and the longest possible life of the equipment.

5.1 Periodic Maintenance Schedule

Interval

3 to 6 months

Check point Check and measures Remarks

Exposed nuts and bolts on antenna unit

Check for corroded or loosened nuts and bolts. If necessary, clean and repaint them thickly.

Replace them if heavily corroded.

Sealing compound may be used instead of paint. Apply a small amount of grease between nuts and bolts for easy removal in future.

Antenna radiator Check for dirt and cracks on radiator surface. Thick dirt should be wiped off with soft cloth dampened with fresh water. if a crack is found, apply a slight amount of sealing compound or adhesive as a temporary remedy, then call for repair.

Do not use plastic solvent

(acetone) for cleaning. If you need to remove ice from antenna unit, use a wooden hammer or plastic head hammer. Crack on the unit may cause water ingress, causing serious damages to internal circuits.

-5.1-

6 months to one year

Terminal strips and plugs in antenna unit

CRT and surrounding components

Terminal strips, sockets, earth terminal

Open antenna cover to check terminal strip and plug connections inside. Also check the rubber gasket of antenna covers for deterioration.

When closing antenna covers in position, be careful not to catch loose wires between covers and unit.

High voltage at CRT and surrounding components attract dust in environment which will cause poor insulation. Ask your nearest FURUNO representative or dealer to clean internal high-voltage components.

If CRT anode rubber cap or wire sheath is cracked, ask your dealer to replace it. Wait for at least 3 minutes until high voltage components (CRT and HV capacitors) discharge their residual charges before accessing them.

Check for loose connections.

Check contacts and plugs for proper seating, etc.

Chapter 6 TROUBLESHOOTING

WARNING

Do not open the equipment.

Hazardous voltage which can cause electrical shock exists inside the equipment. Only qualified personnel should work inside the equipment.

Turn off the radar power switch before servicing the antenna unit. Post a warning sign near the switch indicating it should not be turned on while the antenna unit is being serviced.

Prevent the potential risk of being struck by the rotating antenna and exposure to

RF radiation hazard.

Wear a safety belt and hard hat when working on the antenna unit.

Serious injury or death can result if someone falls from the radar antenna mast.

This paragraph describes how to cure operational problems, which can be made by observing the radar picture and using operator controls and keys without opening the display unit, antenna unit or other equipment units.

The table below shows user-level troubleshooting procedures.

Problem Remedy

Key beep inaudible

No own ship mark

Adjust key beep level on RADAR 2 menu referring to paragraph 1.32.

On the R-type, check that SHIP’S MARK ON is selected at the RADAR 2 menu, referring to section 1.32. Also, own ship information (length, width, etc.) should have been entered in initial settings. Consult your service representative or

Furuno dealer for details. On the IMO-type, the own ship marks is not available.

-6.1-

This paragraph describes how to cure hardware and software troubles which should be carried out by qualified service personnel.

Note: This radar equipment contains complex modules in which fault diagnosis and repair

down to component level are not practicable by users.

Serviceman qualification

All adjustments of radio transmitter during or coinciding with the installation, servicing, or maintenance which may affect the proper operation must be performed by or under the immediate supervision and responsibility of a person holding an operator certificate containing a ship radar endorsement.

This is what the U.S. Codes of Federal Regulations part 80.169 implies (not exact extract).

As such, every administration sets forth its own rule; service personnel must be aware of this kind of competency requirements.

Service call

When making a service call to your service agent, check S/N and symptom beforehand.

Chapter 8 ANCILLARY EQUPMENT

A performance monitor is required for a radar installed on vessels of 300 GT and upward engaged in international voyages. For X-band radars, the FURUNO PM-30 or PM-50 satisfies the requirement covering 9410 ± 50 MHz. For S-band radars, the PM-50 is available covering

3050 ± 30 MHz. The following describes how to use these performance monitors.

The performance monitor is an independent unit, namely, it is not interconnected with any unit of the radar system except for the 100 VAC power cable. In some radars the power cable is not routed via the power switch or other control of the radar and the monitor is operated as completely a separate device.

Operating the performance monitor

When Radar Interswitch RJ-7 is connected, set it to the "straight" mode. Press the PM ON/OFF button in the Turning Compartment, and the range scale is automatically set to 24 nm. The radar screen will show several arcs, opposite to the heading marker (provided that the performance monitor is installed behind the radar antenna as is normally the case). If the radar transmitter and receiver are in good working conditions in as much as the original state when the monitor was turned up, the innermost are should appear at 12 nm and there should be a total of 4 arcs.

The range of the innermost arc reduces 3 nm with every 3 dB loss of transmitted power.

Meanwhile the receiver sensitivity can be evaluated from the number of visible arcs; one arc is lost every 3 dB deterioration of the sensitivity.

8.3 For Fishing Vessel

This radar can be customized as a fishing vessel version with an internal setting. The fishing vessel version offers an additional picture setup option "BIRD," which is assignable to one of the function keys depending on a setting on FUNCTION KEY 1, 2 or 3 menu shown below.

If the BIRD option is menu-selected at the time of installation, the corresponding function key is labeled "BIRD." Press the function key "BIRD" and the radar will be set for optimum detection of sea birds between 6 and 16 nm. As is well known by professional fishermen, locating a flock of sea birds is useful for finding certain species of fish.
