1. OPERATION
1.3 Turning Power On/Off
Press the [POWER/BRILL] key to turn on the
power. The unit beeps, the startup screen
appears, and then the equipment checks the
ROM and RAM for proper operation and
displays program number. The ROM and
RAM check shows OK or NG (No Good). If
NG appears, try to press any key except the
[POWER/BRILL] key to start operation.
However, the equipment may not work
properly. Contact your dealer for advice.
Note 2: The example screens shown in this
manual may not match the screens you see
on your display. The screen you see depends
on your system configuration and equipment
settings.
1.4 Transmitting, Standby
After the power is turned on and the
magnetron has warmed up, “ST-BY”
(Stand-by) appears, indicating the radar is
ready to transmit radar pulses.
To toggle between transmit and stand-by, do
the following:
1. With the power turned on, press the
[POWER/BRILL] key momentarily to show
the brilliance/contrast adjustment window.

After the completion of the startup test, a
timer displays the time remaining for warm up
of the magnetron (the device which transmits
radar pulses), counting down from 1:00 to
0:00.
To turn off the power, press and hold down
the [POWER/BRILL] key (about three
seconds) until the screen goes blank.
Provided that the radar was once in use with
the transmitter tube (magnetron) still warm,
you can turn the radar into TRANSMIT
condition without 1-minute of warm-up. If the
[POWER/BRILL] switch was accidentally
turned off and you want to restart the radar
promptly, turn on the [POWER/BRILL] switch
not later than 15 seconds after power-off.
Note 1: In a cold environment the screen
appears “foggy” when the power is turned on
but is soon restored to normal condition.

2. Press the [MODE] key to go to stand-by
and transmit status alternately.
Note: If you attempt to transmit before
“ST-BY” appears, the beeps sound and
the radar does not transmit pulses. Wait
until “ST-BY” appears.
3. Press the [MENU/ESC] key to close the
window.
When radar pulses are transmitted the radar
receiver is automatically tuned. Echoes
appear in four levels of digitized video
according to echo strength. When a target is
beneath a marker (VRM, EBL, heading line,
range ring) the part of the marker where the
target lies is displayed in reverse video.

are erased when there is no operation within
about 10 seconds.
Note 2: The radar starts up with the last-used
brilliance level after the startup screen
appears. Therefore, adjust the brilliance if it is
too low at startup.
1.6 Choosing the Range
The range selected automatically determines
the range ring interval, the number of range
rings and pulse repetition rate.
Press the [RANGE+] or [RANGE-] key to
choose the range. The range and range ring
interval appear at the top left corner on the
screen.
1.7 Receiver Sensitivity
The [GAIN] key adjusts the sensitivity (gain)
of the receiver. It works in precisely the same
manner as the volume control of a broadcast
receiver, amplifying the signals received.
To set the sensitivity, you first choose the
automatic sensitivity setting which best
matches current sea condition. Then, if
necessary, you may fine tune the sensitivity
manually. The proper setting is such that the
background noise is just visible on the
screen.
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.

In rough weather, returns from the sea
surface, called sea clutter, are received over
several miles around own ship and mask
nearby targets. This situation can be
improved by properly suppressing the sea
clutter with the A/C SEA control.

Automatic A/C SEA adjustment
In most cases suppress the clutter until it has
disappeared to leeward, but a little is still
visible windward. If the 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.
A common mistake is too over-suppress sea
clutter so that it is completely removed. You
can see how dangerous this can be by setting
up for maximum A/C SEA: A dark zone will be
created near the center of the screen,

The bearing to a target can be measured by
the range rings, by the cursor and by the
VRM (Variable Range Marker).
4. Press the [MENU/ESC] key to finish.
1.9 Suppressing Rain Clutter
The vertical beamwidth of the antenna is
designed to see surface targets even when
the ship is rolling. However, by this design the
antenna will also pick up rain clutter (rain,
snow, or hail) in the same manner as normal
targets. The illustration below shows the
appearance of rain clutter on the display.
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).
The higher the setting the greater the
anti-clutter effect.

1. OPERATION
1.20 Guard Alarm
How guard zone type is determined
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, audio and visual
alarms are released to call your attention.
The alarms will be released for targets
entering or exiting the zone depending on the
presence or absence of targets in the zone
when the alarm is set.
After the guard zone has been set, the radar
checks for targets inside the guard zone,
which takes about 8 to 12 seconds. When the
check is completed, “G(IN)” or “G(OUT)”
replaces G(---) at the top right corner.
NOTICE
* The alarm should not be relied upon as the
sole means for detecting possible collision
situations.
G(IN): When no target exists in the zone,
"G(IN)" appears. The audio alarm sounds
against targets which enter the guard zone.
G(OUT): If there are targets in the guard
zone, "G(OUT)" appears. The audio alarm
sounds against all targets which exit from the
guard zone.
* A/C SEA, A/C RAIN, FTC and GAIN controls
should be properly adjusted to be sure the
weak echoes will not be missed by the alarm.
Setting a guard zone
(a) Inward target alarm
1. Operate the cursor pad to place the
cursor at the top left corner for the zone
and then press the [ALARM] key.
2. Operate the cursor pad to place the

Silencing the audio alarm
When a target violates the guard zone, the
target flashes and the audio alarm sounds.
You can silence the audio alarm with the
[ALARM] key. The target continues flashing
until it no longer violates the guard zone or
the guard zone is canceled.

1. OPERATION
1.21 Watchman
The radar "wakes up" at specified time
intervals (5, 10, or 20 minutes) and operates
for 10 scans, the start of which is announced
by releasing the audio alarm. If change is
found in the guard zone from the previous 10
scans, the audio alarm sounds and the radar
resumes normal operation, canceling the
watchman mode. If no change is found, the
radar goes into stand-by, for the specified
time interval. This feature is useful for
periodic watch of the guard zone.

AUTO to automatically change the antenna
rotation speed (24-41 rpm) according to pulse
length*. Choose “24 rpm” to rotate the
antenna at 24 rpm regardless of pulse length.
WIND SPD/DIR: True is the speed and
direction (in relation to ship’s bow) of the wind
felt or measured when stationary. Apparent
is the direction (in relation to ship’s bow) and
speed of the wind as it appears to those on
board, relative to the speed and direction of
the boat; combination of the true wind and the
wind caused by the boat’s movement.
Requires wind data.

Check for corrosion and if
tightly fastened.
Replace corroded bolts. Coat new
bolts with anticorrosive sealant.
Antenna unit
cleanliness
Check for foreign material.
(Foreign material on the
antenna unit can cause a
considerable drop in
sensitivity.)
Clean the antenna unit with a
freshwater-moistened cloth.
Alcohol may be used. Do not use
commercial cleaners to clean the
antenna unit; they can remove
paint and markings or deform the
equipment.
Antenna unit
cover
Check for cracks. Permanent
damage to the unit’s circuitry
will result if water leaks inside.
If a crack is found, it should be
temporarily repaired by using a
small amount of sealing compound
or adhesive. The unit should then
be brought to your dealer for
permanent repairs.
Display unit
case, LCD
The display case and LCD will,
in time, accumulate a coating
of dust, and dust on the LCD
tends to dim the picture.
Wipe the LCD carefully to prevent
scratching, using tissue paper and
an LCD cleaner. To remove dirt or
salt deposits, use an LCD cleaner,
wiping slowly with tissue paper so
as to dissolve the dirt or salt.
Change paper frequently so the
salt or dirt will not scratch the LCD.
Do not use commercial cleaners to
clean the display unit; they can
remove paint and markings or
deform the equipment.

When choosing a mounting location for the
antenna unit, keep in mind the following
points:
Bow
• Install the antenna unit on the hardtop,
radar arch or on a mast on an appropriate
platform. (For sailboats, a mounting bracket
is optionally available.) It should be placed
where there is a good all-round view with,
as far as possible, no part of the ship’s
superstructure or rigging intercepting the
scanning beam. Any obstruction will cause
shadow and blind sectors.
