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.
The number of display units which may be installed depends on the number of network
sounder connected. For a system incorporating three or more products, a “hub” is required
to process data.
For one network sounder: one radar and three plotters, or four plotters
For two network sounder: one radar and two plotters, or four plotters

Inserting a Chart Card
Your unit reads SD cards, in the following formats: Navionics GOLD Chart cards or C-MAP
NT MAX chart cards, depending on the type of display unit you have. Insert the appropriate
chart card for your area as follows:
1. Open the chart drive.
Chart slot
Display unit
2. Insert chart card label side up.
3. Close the lid.
To remove chart card, push the card once and then pull it out.
Note 1: Do not remove a card while the chart is being drawn. This may cause the
equipment to freeze.
Note 2: Do not insert or remove a card while the power is on. This may cause the
equipment to freeze.
Note 3: For multiple display units, do not use the same chart card type in more than one
display unit.
Note 4: Remove the card with care; rough handling can damage the card and destroy its
contents.

Turning the Unit On/Off
Press the POWER/BRILL key to turn the unit on. A beep sounds and then the equipment
shows the startup NavNet screen (about 20 seconds), the product information screen,
startup test results and chart usage disclaimer. During this period the equipment is
inoperative. The startup test checks the ROM, RAM, internal battery and backup data for
proper operation, displaying the results for each as OK or NG (No Good). If NG appears an
appropriate message appears on the screen. For any NG, try to press any key to go to the
chart disclaimer screen, then perform the diagnostic test as shown in the paragraph “8.6
Diagnostics.”
For start up with the radar display, the magnetron takes from 60 seconds to 90seconds
(depending on radar model) to warm up before the radar can be operated. The time
remaining for warming up of the magnetron is counted down at the center of the display.
You may press any key at the chart disclaimer screen to show the last-used display, or wait
several seconds to let the equipment do it for you.
To turn the unit off, press and hold down the POWER/BRILL key until the screen goes dark
(approx. 3 sec.). To protect the LCD attach the hard cover. Note that the network sounder
will be turned off approx. three minutes after turning off the power. This is due to the
system’s electrical characteristics.
Note: The first time you turn on the power (or any time the power is applied after a memory
reset), you are asked if you want to start the simulation mode, which provides simulated
operation of the equipment after the installation mode selection. Push the ENTER knob to
start the simulation mode, or press the CLEAR key to start normal operation. For further
details about the simulation mode, see the paragraph “1.10 Simulation Display.”

Adjusting the Gain
The GAIN key adjusts the gain sensitivity of the radar receiver. It works in a manner similar
to that of 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:

5. Press the GAIN key on the front panel or the RETURN soft key to finish.
Adjusting the FTC
To suppress rain clutter from heavy storms or scattered rain clutter, adjust the FTC.
In addition to reducing clutter, the FTC can be used in fine weather to clarify the picture
when navigating in confined waters. However, with the circuit active the receiver is less
sensitive.
1. Press the GAIN key.
2. Press the FTC soft key, and then rotate the ENTER knob toadjust.
3. Press the GAIN key on the front panel or RETURN soft key to finish.
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.

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.

Radar interference may occur when near another shipborne radar that is operating in the
same frequency band as your radar. Its on-screen appearance looks like many bright dots
either scattered at random or in the form of dotted lines extending from the center to the
edge of the display. Interference effects are distinguishable from normal echoes because
they do not appear in the same place on successive rotations of the scanner.
Be sure to turn off the interference rejector when no interference exists – weak targets may
be missed.

The echo average feature, which requires a Model 18x4/19x4 series network radar as radar
source, 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.
OFF: No averaging
LOW: Helps distinguish targets from sea clutter and suppresses brilliance of unstable
echoes.
MED: Distinguishes small stationary targets such as navigation buoys.
HIGH: Stably displays distant targets.
4. Press the RETURN soft key to finish.

2.22 Guard Alarm
The guard alarm allows the operator to set the desired range and bearing for a guard zone.
When ships, islands, landmasses, etc. violate the guard zone, an audio alarm sounds and
the offending target blinks to call the operator’s attention.
CAUTION
• The alarm should not be relied upon as
the sole means for detecting possible
collision situations.
• A/C SEA, A/C RAIN and GAIN controls
should be properly adjusted to be sure
the alarm system does not overlook
target echoes.
2.22.1 Setting a guard alarm zone
To set a guard alarm zone, set the radar to transmit and do the following:
1. Press the ALARM key.
2. Use the Cursor pad to set the cursor on the top left corner (or top right corner) of the
guard zone you want to set, then press the SET GUARD1 or SET GUARD2 soft key,
depending on which guard zone you want to set.

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 “G1 (G2) IN” or “G1 (G2)
OUT” changes to “G1 (G2) ***.” The guard alarm function is not available while this
indication appears.
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.
2.22.2 When the alarm is violated…
Any radar target violating the guard zone will flash, the audio alarm sounds, and the alarm
icon appears in red. Additionally the message “TARGET ENTERED INTO
GUARD1(GUARD2)” or “TARGET LEFT FROM GUARD1(GUARD2)” is displayed at the
bottom of the screen. Press the CLEAR key to silence the alarm.

2.23 Watchman
2.23.1 How watchman works
The watchman function periodically transmits radar pulses for one minute to check for
targets in a guard zone. If a target is found in the zone, watchman is cancelled, the audio
alarm sounds and the radar continues transmitting. If no target is found the radar goes into
standby for the number of minutes specified on the RADAR DISPLAY SETUP menu. This
feature is useful when you do not need the radar’s function continuously but want to be
alerted to radar targets in a specific area. “WTCH” appears at the top left corner when

2.25 ARP, TTM Operation
When the radar source is an ARP-equipped Model 18x4/19x4 series network radar, 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.
Note: When using your unit as remote display, you cannot change the range of the main
radar at the remote display. For the target acquisition, set the range individually.
Usage precautions for ARP
CAUTION
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 landmass, 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.
2-28
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)

2.25.8 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 red). 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:
1. Press the MENU key followed by the ARP SETUP soft

2.26 Interpreting the Radar Display
2.26.1 False echoes
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.
True
echo
Target
Own ship
Multiple
echo
Multiple echoes
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 sector
Funnels, stacks, masts, or derricks in the path of the

non-detecting sector or blind spot may be produced.
Within this sector, targets can not be detected.

2.26.2 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 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.

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.
2.26.3 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.

details see paragraph 7.10.
Compass display
The compass display, shown in combination displays, provides steering information. The
compass rose shows two triangles: the red triangle shows own ship’s course and the black
triangle, which moves with ship’s course, shows the bearing to destination waypoint.
The water temperature and depth graphs, which require appropriate sensors, show the
latest 10 minutes of water temperature and depth data. The range of the depth graph is 50
feet and it is automatically adjusted with depth. You may adjust the update interval for these
graphs on the NAV GRAPHIC DISPLAY SETUP menu.

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 is shown in black when the amount of cross-track error
is within the XTE monitor range and yellow when it is over. An arrow appears at the right or
left side of the XTE monitor and it shows the direction to steer to return to intended course.
It is shown in red when you should steer left, and green when you should steer right. 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.
Soft keys
You can show the soft keys for the compass display by pressing the HIDE/SHOW key.
EDIT XT-LMT: Sets the range for XTE monitor scale. See the procedure below for how to

Highway display
The highway display, shown in 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 the 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.

Presentation Mode
Three types of presentation modes are provided for the plotter display: north-up, course-up
and auto course-up. To change the presentation mode, press the HIDE/SHOW key followed
by the MODE soft key. Each press of the key changes the presentation mode and
presentation mode indication (top right-hand corner of the screen) cyclically in the sequence
of North-up, Course-up and Auto course-up.
For C-map model, the sequence is North-up, Perspective, Course-up and Auto course-up
when PERSPECTIVE DISPLAY is set to ON, on the CHART DETAILS menu. (See Chapter
7.)
North-up
North (zero degree) is at the top of the display and own ship is shown with a filled circle.
This mode is useful for long-range navigation.
Course-up
34° 22. 3456'N
080° 22. 3456'E
The course-up mode is useful for monitoring
ship’s progress towards a waypoint. The
destination is at the top of the screen when a
destination is set. When no destination is set,
the course or heading is at the top of the screen
at the moment the course-up mode is selected.
A filled triangle marks own ship’s position.
Note: The data sentences GGA and VTG must
be output from the NavNet display unit
connected to the GPS navigator in order to
correctly orient the own ship marker in the
course-up mode on other NavNet display units.

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 1-13 for details), by
cursor, by range and bearing, and through the waypoint list (manual input of latitude and
longitude).

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.

3.11 Alarms
The plotter section has eight conditions which generate both audio and visual alarms:
arrival alarm, anchor watch alarm, XTE (Cross Track Error) alarm, proximity alarm, speed
alarm, trip alarm, water temperature alarm and bottom alarm. (The bottom and water
temperature alarms, which require depth and water temperature data, may also be set on
the sounder alarm menu. For these alarms see Chapter 4.)
You may set up the plotter alarms on the ALARM menu, which may be displayed by
pressing the ALARM key.

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.
4.2.1
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 reddish brown (default
color arrangement).
Clutter, which suppresses low level noise, is automatically adjusted.
4.2.2
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.

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.

Picture Advance Speed
The picture advance speed determines how quickly the vertical scan lines run across the
screen. When selecting a picture advance speed, keep in mind that a fast advance speed
will expand the size of the fish school horizontally on the screen and a slow advance speed
will contract it.
The advancement speed may be set independent of or synchronized with ship’s speed.

Advancement synchronized with ship’s speed
With speed data provided by a speed-measuring device, picture advance speed may be set
according to ship’s speed, the ship’s speed dependent mode. As shown in the figure below
the horizontal scale of the display is not influenced by the change of ship’s speed, thus the
speed-dependent picture advance permits judgment of fish school size and abundance at
any speed. The choice “SPD SENSING PRR” means the ship’s speed dependent mode,
where the PRR changes automatically with ship’s speed.
Fish school shrinks as speed
is increased; expanded
as speed is decreased.

4. VIDEO SOUNDER OPERATION
4.15.2 Bottom echo
Echoes from the bottom are normally the strongest and are displayed in reddish-brown, but
the color 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 color 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.

4.15.3 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.

4.15.4 Surface noise/Aeration
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.

What is MGRS?
For convenience, the world is generally
divided into 6° by 8° geographic areas,
each of which is given a unique
identification, called the Grid Zone
Designation. These areas are covered by
a pattern of 100,000-meter squares.
Each square is identified by two letters
called tie 100,000-meter square
identification. This identification is unique
within the area covered by the Grid Zone
Designation. Exceptions to this general
rule have been made in the post to
preserve the 100,000-meter
identifications on mapping that already
exists.
A reference keyed to a gridded map of
any scale is made by giving the 100,000meter square identification together with
the numerical location. Numerical
references within the 100,000-mater
square are given to the desired accuracy
in terms of the easting (E) and northing
(N) grid coordinates for the point. The
Grid Zone Designation usually is prefixed
to the identification when references are
made in more than one grid zone
designation area.
Examples of MGRS indications:
18S: Locating a point within the Grid
Zone Designation
18SUU: Locating a point within a
100,000-meter square
18SUU80: Locating a point within a
10,000-meter square
18SUU8401: Locating a point within a

Geodetic 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.
See Appendix for full list.

Position 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.
0-999 seconds
Spd/Cse Smoothing
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.

the minimum echo strength which will
trigger the fish alarms.

Transmission
Turns TX power on/off.
TVG
(HF,LF)
TVG (Time Varied Gain) compensates 0-9
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.
Echo Offset
(HF, LF)
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.
-50 - +50
Bottom Level
(HF, LF)
If the depth indication is unstable in
automatic operation or the bottom
echo cannot be displayed in
reddish-brown by adjusting the gain
control in manual operation, you may
adjust the bottom echo level detection
circuit, for both HF and LF, 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.

Settings
Adjusts STC level for the high and low 0-10
frequencies, and is useful for
suppressing surface noise. The
setting range is 0-10; the higher the
setting the greater the extent of
suppression. Setting 10 suppresses
noise up to several meters. Turn off
the STC when there is no noise on the
