1. OPERATION
1.3 Turning Power On/Off
1.4 Transmitting, Standby
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.
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.

2. Press the [MODE] key to go to standby
and transmit alternately.
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.
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.
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.
When radar pulses are transmitted the radar
receive is automatically tuned. Echoes
appear in four levels of digitized video
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.

4. Press the [MENU/ESC] key to escape.
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.
Note 1: Windows other than menu windows
are erased when there is no operation within
about 10 seconds.
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.
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.
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.
1.6 Choosing the Range
The range selected automatically determines
the range ring interval, the number of range
rings and pulse repetition rate.
1. Press the [GAIN] key consecutively until
the display shown below appears.

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) Press ► to open the automatic A/C
SEA options window.

MODERATE
CALM
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.

1.10 Measuring the Range
While observing the screen and the A/C
SEA tuning bar, press ◄ or ► to set the
A/C SEA. The setting range is 0-100.
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.
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.
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.
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.
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.
Note: The range rings can be turned on or off
with RINGS on page 1 of the System menu.

in the same frequency band (9 GHz). It is
seen on the screen as a number of bright
spikes either in irregular patterns or in the
form of usually curved spoke-like dotted lines
extending from the center to the edge of the
picture. This type of interference can be
reduced by activating the interference rejector
circuit. “IR” and the rejection level indicator
“L,” “M” or “H” appear at the top right corner

How guard zone type is determined
1.20 Guard Alarm
After the guard zone is set, the system
checks for the existence of 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.
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 audio alarm
sounds to call your attention. The alarm will
sound on targets entering or exiting the zone
depending on zone status after the alarm has
been set.
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.
NOTICE
The alarm should not be relied upon as the
*
sole means for detecting possible collision
situations.
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.

1. OPERATION
SHIFT MODE: Own ship position, or sweep
origin, can be displaced manually or
automatically. For automatic displacement,
the amount of shift is calculated with ship
speed, and the amount is limited to 60% of
the range in use. For example, if the “Auto
Shift Speed” setting is 15 knots and the ship
is running at 10 knots, the amount of shift will
be about 40%. The formula for determining
shift amount is as below. Requires speed
data.
Waypoint

EBL REFERENCE: The EBL readout may be
chosen from relative (relative to own ship’s
heading) or true (referenced to the North).
Heading data required for true bearing.

X 0.6 = Amount of shift(%)
Shift speed setting
AUTO SHIFT SPEED: Sets the automatic
shift maximum speed. The setting range is
1-99.
Note: If no bearing data is input, course data
from the GPS navigator is used. In this case
ship’s speed must be more than two knots.
TX SECTOR BLANK: In some installations it
may be unavoidable to locate the antenna
where an object (mast, etc.) will prevent
transmission within its breadth. You should
disable transmission within this area by
turning on this feature and setting the area
with BLANKING START and BLANKING
AREA below.
BEARING READOUT: Course indication may
be shown in true or magnetic (magnetic
compass) degrees. Heading data required for
true degrees.
CURSOR POSITION: Chooses the
information to show for the cursor position:
latitude and longitude or range and bearing
from own ship. Latitude and longitude
position requires a navigator.
BLANKING START: Sets the starting point
(000-359°) of the TX sector blanking area.
TRIP SOURCE: Chooses the criteria for
calculating distance run: latitude and
longitude or speed. Requires navigator or
speed log.
BLANKING AREA: Sets the end point of the
TX sector blanking area (000-135°).
LOCAL TIME SETUP: Enter time difference
between local time and UTC time to use local
time. Press ▲ or ▼ to set value.
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.
ANTENNA SPEED: Chooses antenna
rotation speed from 24 rpm and AUTO. Use
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.

•
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.

mounting hardware
2. At the mounting location for the antenna
unit, construct a platform (wood, steel, or
aluminum) of 5–10 mm in thickness on
whose dimensions are as shown below
Next, position the antenna unit on the
platform so the cable entrance faces the
stern direction and the vent tube is
extending downward through the hole for
the vent tube.
