1.5 Operation Conventions
The main radar (Model 1712 or 1622) must
be powered and transmitting to display the
radar picture on the remote display. If the
main radar is off, in standby, or there is
antenna trouble, the remote display shows
the indications HD-SIG-MISS and BP-SIGMISS.
RANGE, GAIN and STC controls
• The RANGE, GAIN and STC controls are
commonly set. (Other controls may be
independently set.) That is, when one of
those controls is adjusted, the main radar
or remote display receiving the command
is automatically set accordingly. STC and
GAIN adjustment methods (automatic
and manual) are also commonly
switched.
• The last-operated control among GAIN,
RANGE and STC takes priority when the
main radar and remote display are
operated simultaneously. Therefore, if
your command was not accepted the
reason may be simultaneous operation.
• Range is commonly set regardless of
range setting on the menu of the main
radar and remote display. For example,
the remote display selects the 2 nm range.
The main radar also sets the 2 nm range
even if it is turned off on its menu.
Watchman
The watchman feature, disabled or enabled
at the main radar, periodically transmits
pulses to check for targets in the guard
zone. For further details, see the Operator’s
Manual for the main radar.
• The indication “WATCHMAN” appears on
the remote display and main radar when
watchman is active.
• The indication is shown in white on black
background for two seconds on the
remote display when the [RANGE] key on
the remote display is operated while
Watchman is in standby. (Range
command is not accepted in this case.)
• Operating any key among GAIN, RANGE
and STC from the remote display while
the watchman is transmitting will
automatically cancel the watchman, and
the radar transmits continuously.
Watchman cannot be canceled from the
remote display when it is in standby.
Guard zone
The guard zone may be independently set.

1.8 Receiver Sensitivity
The [GAIN] key adjusts the sensitivity of the
receiver. It works in precisely the same
manner as the volume control of a
broadcast receiver, amplifying the signals
received.
You can adjust the sensitivity manually, or
let the unit do it automatically. In either case
the proper setting is such that the
background noise is just visible on the
screen. For manual adjustment, adjust the
sensitivity on the highest range since the
background noise is clearer on that range.
If you set up for too little sensitivity, weak
echoes may be missed. On the other hand
excessive sensitivity yields too much
background noise; weak targets may be
missed because of the poor contrast
between desired echoes and the
background noise on the display.

Note: The dialog boxes for adjustment of
sensitivity are automatically erased
when there is no Omnipad operation
for 10 seconds. To erase them
quicker, press the [GAIN] key after
completing the setting.
1.9 Suppressing Sea Clutter
In rough weather, returns from the sea
surface are received over several miles
around own ship and mask nearby targets.
This situation can be improved by properly
using the [STC] key.
If the STC setting is too low, targets will be
hidden in the clutter, while if it is set too high,
both sea clutter and targets will disappear
from the display. In most cases adjust the
key until clutter has disappeared to leeward,
but a little is still visible windward.
A common mistake is too over-adjust the
[STC] key so that the surface clutter is
completely removed. By setting up for
maximum STC effect, you will see how
dangerous this can be; a dark zone will be
created near the center of the screen,
causing a loss of close-in targets. This dark
zone is even more dangerous if the
sensitivity has not been properly adjusted.
Always leave a little surface clutter visible
on the screen. If no clutter is observed (on
very calm waters), choose lowest STC
setting.

1.10 Suppressing Rain Clutter
In adverse weather, clouds, rain or snow
produce spray-like spurious echoes which
impair target detection over a long distance.
These echoes can be suppressed by
turning on the [FTC] (Fast Time Constant)
key. FTC appears at the top right-hand
corner on the screen when the FTC is on.
Turn off the FTC when its use is not
required so as not to miss weak targets.

1.11 Range Rings
1.14 Measuring the Range
The range rings are the concentric circles
around own ship and they provide an
estimate of target range. The selected
range scale automatically determines the
number of rings and their interval is
displayed at the upper-left-hand corner on
the screen.
The bearing to a target can be measured by
the range rings, by the cursor (see
paragraph 1.12) and by the VRM (Variable
Range Marker).
To turn the range rings on or off, press the
[EBL] and [VRM] keys together.
1.12 Cursor
The cursor is always displayed and
functions to measure the range and bearing
to a target. Operate the Omnipad to place
the cursor on the inside edge of the target
for range measurement or the center of the
target for bearing measurement. The range
and bearing to the cursor appear at the
bottom right-hand corner on the display.
6.0 NM

Measuring range by the range rings
Count the number of rings between the
center of the display and the target. Check
the range ring interval at the top left-hand
corner of the screen and judge the distance
of the echo from the inner edge of the
nearest ring.
Measuring range by the VRM
1. Press the [VRM] key to turn on the VRM.
2. Within 10 seconds after turning on the
VRM, that is, while "VRM" is highlighted
at the bottom left-hand corner on the
screen, press (increase radius) or
(decrease radius) to place the VRM on
the inside edge of the target.
3. Check the VRM readout at the bottom
left-hand corner on the screen.

1.21 Guard Alarm Zone
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 the offending target
flashes and an aural alarm sounds to call
the operator’s attention. The alarm is
triggered against targets entering or exiting
the guard zone depending on guard zone
type as below.
CAUTION
* The alarm should not be relied upon as the
sole means for detecting possible collision
situations.
* STC, FTC and GAIN controls should be
properly adjusted to be sure the alarm
system does not overlook target echoes.
How guard zone type is determined
After the guard zone is set, the radar starts
searching for targets inside the guard zone
for about 8 to 12 seconds. The results of the
search are shown at the top right-hand
corner of the display as “G (IN)” or “G
(OUT).”
G (IN): This is the inward guard alarm and it
means no target was found in the guard
zone. The guard alarm will be triggered by
targets entering the guard zone.
G (OUT): This is the outward guard alarm
and it means a target was found in the
guard zone. The guard alarm will be
triggered by targets exiting the guard zone.

1.23 Echo Stretch
1.24 Navigation Data
On long ranges target echoes tend to shrink
in the range direction, making them difficult
to see. On short and medium ranges such
as 1.5, 3 and 6 nm range scales, the same
sized targets get smaller on screen as they
approach own ship. To enhance target
video, use the echo stretch feature.
With navigation data input in NMEA 0183
format (IEC 61162-1), navigation data can
be displayed at the screen bottom.

3. INSTALLATION
3.1 Display Unit Installation
Mounting considerations
The display unit can be mounted on a
desktop, the overhead, or flush mounted in
a panel. See the next page for mounting
dimensions.
When selecting a mounting location for the
display unit keep in mind the following
points.
• Locate the display unit in a position where
you can view and operate it conveniently.
• The orientation of the display unit should
be so that its screen is viewed while the
operator is facing in the direction of the
bow. This makes determination of your
position much easier.
• The display unit is designed and
constructed to be splashproof, thus it can
be installed outdoors. If it is to be installed
outdoors, we recommend installing it an
enclosed cabinet, for maximum protection
against the marine environment.
• Even though the picture is quite legible
even in bright sunlight, keep the display
unit out of direct sunlight or at least
shaded because of heat that can build up
inside the cabinet.
• The temperature and humidity of the
mounting location should be stable and
moderate. No LCD can provide adequate
contrast if the ambient temperature is too
low or too high.
• The compass safe distance of 0.90
meters (standard compass) and 0.60
meters (steering compass) should be
observed to prevent deviation of the
magnetic compass.
• Make sure you allow enough clearance
both to get to the connectors behind the
unit and to allow you to get your hands in
on both sides to loosen or tighten the
mounting knobs.
• Leave at least a foot or so of "service
loop" in cables behind the unit for
servicing or easy removal of the
connectors.
Removing the cover
While pressing the center of the cover with
your thumbs as illustrated, pull the cover
towards you to remove it.
