Features
The Model 1833/1933/1943 Marine Radar series work within our new product-network system called the “NavNet.” Each product has an IP address to communicate with NavNet compatible products within the network, using TCP/IP protocol through an Ethernet
10BASE-T network.
The main features are as follows:
• The 1833/1933/1943 series consists of the following models:

• Bright 10” screen visible even under direct sunlight.
• User-friendly operation with combination of discrete keys, soft keys, and trackball.
• Accepts FURUNO and NavCharts™ (NAVIONICS) charts, or C-MAP charts, depending on specification.
• Fast chart redraw.
• Built-in NavNet interface circuit board.
• 12-channel GPS Receiver GP-310B with highly accurate position fixing optionally available.
• User programmable function keys.
• Video sounder picture available with connection of the optional Network Sounder
ETR-6/10N.

SYSTEM CONFIGURATIONS
All NavNet products incorporate a “network circuit board” to integrate each NavNet product on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is assigned an IP address to enable transfer of images between other NavNet products. For example, video plotter pictures can be transferred to a radar and vice versa. Pictures received via the NavNet may be adjusted at the receiving end.
A NavNet system may consist of up to four NavNet display units and one network sounder.
For a system incorporating three or more products, a “hub” is required to process data.

1. OPERATIONAL OVERVIEW
1.1.1 Display unit controls
Overview of display unit controls
The radar, video plotter, sounder and chart systems are operated with the controls of the display unit (and the remote controller). Ten keys are labeled and they provide the function shown on their labels. The five soft keys provide various functions according to current operating mode. The [ENTER] knob mainly functions to register selections on the menu and adjust the EBL, VRM and gain. The trackball’s main function is to move the cursor across the screen.
When you correctly execute an operation, the unit generates a beep. Invalid operation causes the unit to emit three beeps.

The [GAIN] key adjusts the sensitivity of the radar receiver. It works in a manner similar to the volume control of a broadcast receiver, which amplifies received signals.
The proper setting is such that the background noise is just visible on the screen.
If your gain setting is too low, weak echoes may be missed. On the other hand, excessive gain yields too much background noise; strong targets may be missed because of the poor contrast between desired echoes and the background noise on the display.
To adjust the receiver sensitivity, transmit on long range, and then do the following:

2.5 Reducing Sea Clutter
2.5.1 How the A/C SEA works
Echoes from waves can be troublesome, covering the central part of the display with random signals known as “sea clutter”. The higher the waves and the higher the antenna above the water, the further the clutter will extend. Sea clutter may affect radar performance because real targets are sometimes hidden by the echoes of small waves. (See the left-hand figure in the figure below.) When sea clutter masks the picture, adjust the A/C SEA to reduce the clutter.
The A/C SEA reduces the amplification of echoes at short ranges (where clutter is the greatest) and progressively increases amplification as the range increases, so amplification will be normal at those ranges where there is no sea clutter.
Sea clutter at screen center
A/C SEA adjusted; sea clutter suppressed
Effect of A/C SEA
A/C SEA should be adjusted so that the clutter is broken up into small dots, and small targets become distinguishable.
1. Press the [GAIN] key.

2.6 Reducing Precipitation Clutter
The vertical beamwidth of the antenna is designed to see surface targets even when the ship is rolling. However, by this design the unit will also detect precipitation clutter (rain, snow, hail, etc.) in the same manner as normal targets.
Precipitation clutter shows as random dots on the screen.
When echoes from precipitation mask solid targets, adjust the A/C RAIN to split up these unwanted echoes into a speckled pattern, making recognition of solid targets easier.
1. Press the [GAIN] key.
2. Press the A/C RAIN soft key to show the A/C RAIN window.

2. RADAR OPERATION
Normally, the reflected echoes from long range targets appear on the display as weaker and smaller blips even though they are compensated by the radar’s internal circuitry. The echo stretch function magnifies these small blips in all ranges. Two types of echo stretch are available: ES LOW which stretches echoes in bearing direction and ES HIGH which stretches them in both range and bearing directions.

2. RADAR OPERATION
The echo averaging feature effectively suppresses sea clutter. Echoes received from stable targets such as ships appear on the screen at almost the same position during 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, echo average 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:
1. If not displayed, press the [HIDE/SHOW] key to display the radar soft keys.
2. Press the SIGNAL PROC. soft key.
3. Press the E. AVG soft key to select desired echo averaging.
LOW: Helps distinguish targets from sea clutter and suppresses brilliance of unstable echoes.

2. RADAR OPERATION
The equipment then searches for targets inside the guard zone to determine guard alarm type. If a target is found inside the guard zone, the guard zone type becomes an “Outward guard alarm,” and any target exiting the guard zone will trigger the audio alarm. If no target is found, the guard zone type becomes an
“Inward guard alarm,” and any targets entering the guard zone will trigger the audio alarm. The guard alarm type is shown as G1(G2) IN or G1(G2) OUT.
Note 1:
When the radar range is less than the guard zone range, the audio alarm sounds and the alarm icon appears. Press the [CLEAR] key to silence the alarm. Press the [ALARM] key and the message
“GUARD1(2) IS OUTSIDE RADAR RANGE” appears. Reselect appropriate range.
Note 2: If the network radar is set to standby while the guard alarm is active, the guard alarm is cancelled. The guard alarm is redisplayed when the radar is set to transmit again.
Note 3:
If the network radar is set to standby while the radar picture is not displayed, the audio alarm sounds. Press the [ALARM] key and the message “STBY MODE HAS BEEN SELECTED. GUARD/WTCHMN

2.26 ARP, TTM Operation
With the optional ARP circuit board, you can manually and automatically acquire and track ten targets. Once a target is acquired automatically or manually it is automatically tracked within 0.1 to 32 nm. If the FURUNO heading sensor
PG-1000 is used, the data sentence “RMC” is necessary.
Alternatively, you can display the tracks of other ships by receiving the data sentence TTM (Tracked Target Message) via the NETWORK or NMEA port on the display unit. However, targets cannot be acquired.
Usage precautions for ARP
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)

2.26.8 CPA/TCPA alarm (ARP)
When the predicted CPA of any target becomes smaller than a preset CPA alarm range or its predicted TCPA less than a preset TCPA alarm limit, an audio alarm sounds and the speaker icon appears. In addition, the target plot symbol of the offending target changes to a triangle and flashes together with its vector. You may silence the audio alarm with the [CLEAR] key. Press the [ALARM] key and the message “COLLISION ALARM” appears. Press the CLEAR ALARM soft key to acknowledge the alarm. The flashing of the triangle plot symbol continues until you intentionally terminate tracking of the target. The ARP continuously monitors the predicted range at the Closest Point of Approach (CPA) and predicted time to
CPA (TCPA) of each track to own ship.
This feature helps alert you to targets which may be on a collision course with own ship. However, it is important that gain, A/C SEA, A/C RAIN and other radar controls are properly adjusted and the ARP is set up so that it can track targets effectively.
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
The CPA/TCPA alarm 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.
Follow the steps shown below to set the CPA/TCPA alarm range:

2.27 Interpreting the Radar Display
2.27.1 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 best to use the shortest possible range as long as the clarity and definition of the picture remain good.
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 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. Rmax is given in the following equation.
R max
= 2.2 x ( h1 + h2 ) where Rmax: radar horizon (nautical miles)
h1: antenna height (m)
h2: target height (m)
Radar horizon
Optical horizon
Radar 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).
2-45
2. RADAR OPERATION
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 the echoes received from two targets, which are at the same range and close together, as separate targets.
Bearing resolution is directly proportional to the antenna length, and inversely proportional to the radar's wavelength.
Range resolution
Range resolution is the ability to display the echoes received from two targets, which are on the same bearing and close to each other, as separate targets.
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, select a range which will put the target as far out to the edge of the radar screen as possible.
Range measurement
Measurement of the range to a target is also a very important function of the radar. There are three means of measuring range: the fixed range rings, the trackball 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 trackball is rolled to place the cursor on the leading edge of the target. Range and bearing to the target is shown at the bottom right-hand corner of the display. 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.
2-46
2. RADAR OPERATION
Occasionally echo signals appear on the screen at positions where there is no target or disappear even if there are targets. False target situations may be recognized, however, if you understand 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. This stray RF is called a “sidelobe.” If a target exists where it can be detected by the sidelobes as well as the main lobe, the side echoes may be represented on both sides of the true echo at the same range. Sidelobes 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 show 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.

Shadow sectors
Funnels, stacks, masts, or derricks in the path of the antenna block the radar beam. If the angle subtended at the antenna is more than a few degrees, a non-detecting sector or blind spot may be produced. Within this sector, targets can not be detected.

2.27.3 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 µ s) through the band before beginning a relatively slow sweep (7.5 µ s) 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 range to the SART is reduced to about 1 nm, the radar display may show also the 12 responses generated during the fast sweeps. These additional dot responses, which also are equally spaced by 0.64 nm, will be interspersed with the original line of 12 dots. They will appear slightly weaker and smaller than the original dots.

2. RADAR OPERATION
General procedure for detecting SART response
1. Use the 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 (if applicable).
3. Turn off the Interference Rejector.
General remarks on receiving SART
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 much 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 and wide bandwidths of 10-25 MHz with short pulses on short ranges.
Any 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 sidelobes
As the SART is approached, sidelobes 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 [A/C SEA] control although it may be operationally useful to observe the sidelobes as they may be easier to detect in clutter conditions and also they will confirm that the SART is near to the ship.
Gain
For maximum range SART detection the normal gain setting for long range detection should be used, that is, with background noise speckle visible.
2-50
2. RADAR OPERATION
A/C SEA control
For optimum range SART detection, this control should be set to the minimum.
Care should be exercised as wanted target 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 nm from the furthest dot back towards own ship.
Some sets have automatic/manual anti-clutter sea control facilities in which case the operator should switch to manual.
A/C RAIN control
This should be used normally (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 should switch to manual.
Note: This SART information is excerpted from IMO SN/Circ 197 Operation of
Marine Radar for SART Detection.
2.27.4 Racon (Radar Beacon)
A racon is a radar transponder which emits a characteristic signal when triggered by a ship’s radar (usually only the 3 centimeter band). The signal may be emitted on the same frequency as that of the triggering radar, in which case it is superimposed on the ship's radar display automatically.
The racon signal appears on the PPI as a radial line originating at a point just beyond the position of the radar beacon or as a Morse code signal (see figure below) displayed radially from just beyond the beacon.

Reading the XTE (cross-track error) monitor
The XTE monitor, located below the compass rose, shows the distance you are off course and the direction to steer to return to course. The own ship marker moves according to direction and distance off course. It flashes when own ship’s cross-track error is more than the XTE monitor range. An arrow appears at the left or right side of the XTE scale and it shows the direction to steer. In the example on the previous page you would steer right to return to course. To maintain course, steer the vessel so the own ship marker stays at the center of the XTE monitor.

The highway display, shown in the combination displays, provides a graphic presentation of ship’s track along intended course. It is useful for monitoring ship’s progress toward a waypoint. The own ship marker shows relation between ship and intended course. The XTE monitor shows the direction and amount your vessel is off course – the arrow shows the direction to steer to return to your course and the numeric the distance you are off course. Using the figure below as an example, you would steer right 0.009 nm to return to course. To maintain course, steer the vessel so the own ship marker stays aligned with the intended course line.

3.6.3 Track plotting method and interval for own ship track
In drawing the own ship track, first the ship’s position fed from position-fixing equipment is stored into the unit’s memory at an interval of time or distance. A shorter interval provides for better reconstruction of the track, but the storage time of the track is reduced. When the track memory becomes full, the oldest track is erased to make room for the latest.
Track plotting method
Track may be plotted by time or distance. The default setting is “time.”
1. Press the [MENU] key followed by the CHART SETUP OPTION and

3.8 Waypoints
In navigation terminology, a waypoint is a particular location on a voyage whether it be a starting, intermediate or destination point. A waypoint is the simplest piece of information your equipment requires to get you to a destination, in the shortest distance possible.
This unit has 999 waypoints into which you can enter position information. You may enter a waypoint five ways: at own ship position, at MOB position (see page
1-15 for details), by cursor, by range and bearing, and through the waypoint list
(manual input of latitude and longitude).
Entering a waypoint at own ship position
Press the [SAVE/MOB] key momentarily to store your position as a waypoint.
This new waypoint is saved to the waypoint list, under the youngest empty waypoint number.

3.9 Routes
Often a trip from one place to another involves several course changes, requiring a series of route points (waypoints) which you navigate to, one after another. The sequence of waypoints leading to the ultimate destination is called a route. Your unit can automatically advance to the next waypoint on a route, so you do not have to change the destination waypoint repeatedly.
You can store up to 200 routes, and a route may have 35 waypoints.

With connection of the optional Network Sounder ETR-6/10N you can show video sounder images on the display.
4.1 Principle Operation
The video sounder determines the distance between its transducer and underwater objects such as fish, lake bottom or seabed and displays the results on screen. It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per second. When a sound wave strikes an underwater object such as fish or sea bottom, part of the sound wave is reflected back toward the source (transducer).
Thus by calculating the time difference between the transmission of a sound wave and the reception of the reflected sound wave, the depth to the object can be determined.
The entire process begins in the network sounder. Transmitter power is sent to the transducer as a short pulse of electrical energy. The electrical signal produced by the transmitter is converted into an ultrasonic signal by the transducer and transmitted into the water. Any returning signals from intervening objects (such as a fish school) are received by the transducer and converted into an electrical signal. The signals are then amplified in the amplifier section, and finally, displayed on screen.
The picture displayed is made up of a series of vertical scan lines, one for each transmission. Each line represents a snapshot of what has occurred beneath the boat. A series of snapshots are accumulated side by side across the screen, and the resulting contours of the bottom and fish between the bottom and surface are displayed.

50 kHz picture
The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse, the wider the detection area. Therefore, the 50 kHz frequency is useful for general detection and judging bottom condition.
200 kHz picture
The higher the frequency of the ultrasonic pulse the better the resolution.
Therefore, the 200 kHz frequency is ideal for detailed observation of fish school.

4.3 Automatic Sounder Operation
Automatic sounder operation is useful when you are preoccupied with other tasks and do not have the time to adjust the display.
4.3.1 How the automatic sounder works
The automatic sounder function automatically selects the proper gain, range scale and clutter suppression level according to the depth. It works as follows:
• The range changes automatically to locate the bottom on the lower half of the screen. The range jumps to one step shallower range when the bottom echoes reach a half way point of the full scale from the top and to one step deeper range when they come to the lower edge of the scale.
• The gain is automatically adjusted to display the bottom echo in the darkest tone.
• Clutter, which suppresses low level noise, is automatically adjusted.
4.3.2 Types of automatic sounder modes
Two types of automatic sounder modes are available: CRUISING and FISHING.
CRUISING is for tracking the bottom, and FISHING is for searching fish schools.
CRUISING uses a higher clutter rejection setting than FISHING therefore it is not recommended for fish detection - weak fish echoes may be erased by the clutter suppression circuit.
4.3.3 How to enable automatic sounder operation
1. If not displayed, press the [HIDE/SHOW] key to show the sounder soft keys.

4.4 Manual Sounder Operation
Manual operation is useful for observing fish schools and bottom using a fixed gain setting.
The gain, range and range shift functions used together give you the means to select the depth you can see on the screen. The basic range can be thought of as providing a “window” into the water column and range shifting as moving the
“window” to the desired depth.
4.4.1 Selecting the manual mode
1. If not displayed, press the [HIDE/SHOW] key to show the sounder soft keys.
2. Press the AUTO/D. BOX soft key to show the mode/frequency window.

4.12 Interpreting the Sounder Display
The zero line (sometimes referred to as the transmission line) represents the transducer’s position, and moves off the screen when a deep phased range is used.
Zero line
Zero line
Shift
Echoes from the bottom are normally the strongest and are displayed in the darkest tone, but the tone and width will vary with bottom composition, water depth, frequency, sensitivity, etc.
In a comparatively shallow depth, a high gain setting will cause a second or sometimes a third or a fourth echo to be displayed at the same interval between them below the first echo trace. This is because the echo travels between the bottom and the surface twice or more in shallow depths.
The tone of the bottom echo can be used to help determine the density of the bottom materials (soft or hard). The harder the bottom, the wider the trace. If the gain is set to show only a single bottom echo on mud, a rocky bottom will show a second or third bottom return. The range should be chosen so the first and second bottom echoes are displayed when bottom hardness is being determined.

4. VIDEO SOUNDER OPERATION
4.12.3 Fish school echoes
Fish school echoes will generally be plotted between the zero line and the bottom. Usually the fish school/fish echo is weaker than the bottom echo because its reflection property is much smaller compared to the bottom. The size of the fish school can be ascertained from the density of the display.
Size of fish school
Small school
Large school
Fish school echoes
When the waters are rough or the boat passes over a wake, surface noise may appear near the zero line. As surface turbulence is acoustically equivalent to running into a brick wall, the bottom echo will be displayed intermittently. Similar noise sometimes appears when a water temperature difference (thermocline) exists. Different species of fish tend to prefer different temperature zones, so the thermocline may be useful to help identify target fish. 200 kHz tends to show shallow thermoclines better than 50 kHz.
In rough waters the display is occasionally interrupted due to below-the-ship air bubbles obstructing the sound path. This also occurs when the boat makes a quick turn or reverses movement. Lowering the picture advance speed may reduce the interruption. However, reconsideration of the transducer installation may be necessary if the interruption occurs frequently.

Datum
Geodetic datum is a reference for geodetic survey measurements consisting of fixed latitude, longitude and azimuth values associated with a defined station of reference. You must have the correct geodetic datum selected in your plotter so that it will reference the correct point on the chart for a given latitude and longitude. Although WGS-84 is now the world standard, other categories of charts still exist. Refer to Appendix for a full list of geodetic datum.

Position
Smoothing
Spd/Cse
Smoothing
When the DOP or receiving condition is unfavorable, the GPS fix may change greatly, even if the vessel is not moving. This change can be reduced by smoothing the raw GPS fixes. A setting between 000 to 999 is available. The higher the setting the more smoothed the raw data. If the setting is too high, the response time required to show a change of latitude and longitude will be too long. This is especially noticeable if the vessel is moving fast. Increase the setting if the GPS fix changes randomly.
During position fixing, ship’s velocity
(speed and course) is directly measured by receiving GPS satellite signals. The raw velocity data may vary too much depending on receiving conditions and other factors. You can reduce this random variance by increasing the smoothing. The higher the smoothing setting, the more the raw data will be averaged. If this setting is high, the response to speed and course changes will slow. For no smoothing, enter all zeroes.
GPS Speed
Averaging
Calculation of ETA is based on average ship’s speed over a given period. If the period is too long or too short, calculation error will result.

Echo
Offset
(50 kHz,
200 kHz)
TVG (Time Varied Gain) compensates for propagation attenuation of the ultrasonic waves. It does this by equalizing echo presentation so that fish schools of the same size appear in the same density in both shallow and deep waters. In addition, it reduces surface noise. Note that if the
TVG level is set too high short range echoes may not be displayed.
If the on-screen echo level appears to be too weak or too strong and the level cannot be adjusted satisfactorily with the gain control, adjust echo offset to compensate for too weak or too strong echoes.
Bottom
Level
(50 kHz,
200 kHz)
If the depth indication is unstable in automatic operation or the bottom echo cannot be displayed in the darkest tone by adjusting the gain control in manual operation, you may adjust the bottom echo level detection circuit, for both 50 kHz and 200 kHz, to stabilize the indication. Note that if the level is set too low weak echoes may be missed and if set too high the depth indication will not be displayed.
