The Mobius loop symbol (three chasing arrows) indicates that Ni-Cd
and lead-acid rechargeable batteries must be recycled. Take the used
batteries to a battery collection site according to local laws.
In the other countries
There are no international standards for the battery recycle symbol. The number of symbols can
increase when the other countries make their own recycling symbols in the future.

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.

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 until the screen
goes blank. The time remaining until power is
turned off is counted down on the screen.
Note: In a cold environment the screen
appears “foggy” when the power is turned on
but is soon restored to normal condition.
.
1.4 Transmitting, Standby
After the power is turned on and the
magnetron has warmed up, “ST-BY”
(Standby) appears, indicating the radar is
ready to transmit radar pulses.
To toggle between transmit and standby, do
the following:
1. Press the [POWER/BRILL] key
momentarily to show the
brilliance/contrast adjustment window.
BRILL/CONTRAST
TX/STBY - PRESS [MODE]
LOW HIGH
CONT: 4

BRILL:
[MENU/ESC] : Exit.
Brilliance/contrast adjustment window
2. Press the [MODE] key to go to standby
and transmit alternately.
Note: If you attempt to transmit before
“ST-BY” appears, the buzzer sounds 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
receive 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.
Note: This can be done with the
above-mentioned procedure or the PROG
key if it is so programmed. For detail, see
1.26 “PROG Key”.

are erased when there is no operation within
about 10 seconds.
Note 2: When the power is reapplied after
turning off the equipment with minimum
brilliance, the radar starts up with minimum
brilliance, after the startup screen appears.
Adjust the brilliance as necessary.
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
select a 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.
The sensitivity is adjusted automatically
according to sea conditions, and you may
also further adjust it manually to fine tune.
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 setting range is 0-100.
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.
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 scr een,
causing a loss of close-in target s. 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 targ et s 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 illustrat ion below shows the
appearance of rain clutter on the display.
The A/C RAIN control adjusts t he receiver
sensitivity as the A/C SEA control does but
rather in a longer time period (long er range).
The higher the setting the greater the
anti-clutter effect .
1.10 Measuring the Range
The bearing to a target can be m easur ed 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 bet ween 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.
Note: The range rings can be t urned on or off
with RINGS on page 1 of the System menu.
