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.

ROM : OK RAM : OK
Program No: 0359199-XX.XX
XX.XX = Program version no.
Startup screen
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.
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.

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

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.

the display shown below appears.

3. Press the [MENU/ESC] key to finish.
1.8 Suppressing Sea Clutter
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.
To set the A/C SEA, you first choose the
automatic A/C SEA setting which best
matches current sea conditions. Then, if
necessary, you may fine tune the A/C SEA
manually.
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,
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 sea clutter visible on the
screen, first adjusting automatically and then
fine tuning with the manual control as
necessary.

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.

1.10 Measuring the Range
The bearing to a target can be measured by
the range rings, by the cursor and by the
VRM (Variable Range Marker).
Measuring range by the cursor
Operate the cursor pad to place the cursor on
the inside edge of the target. Read the range
to the cursor at the bottom right corner of the
display.
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 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 display the VRM.
The message “Adjust VRM by cursor”
appears and “VRM” in the EBL/VRM box
is displayed in reverse video. The
message is automatically erased after 10
seconds, or you may erase it sooner by
pressing any key.
2. Operate the cursor pad to place the VRM
on the inside edge of the target.
3. Check the VRM readout at the bottom left
corner on the screen to find the range to
the target.
To anchor the VRM, press the [MENU/ESC]
key. (It is automatically anchored if there is no
key operation for about 10 seconds.) To
erase the VRM, press the [VRM] key.
