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.  
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.

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.  
Press the [RANGE+] or [RANGE-] key to  
select a range. The range and range ring  
interval appear at the top left corner on the

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) 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.

1.16 Interference Rejector  
Mutual radar interference may occur in the  
vicinity of another shipborne radar operating  
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  
when the interference rejector circuit is on.

1. OPERATION  
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.

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.  
* = Short pulse at high rotation speed; long  
pulse at slow rotation speed.

When selecting a mounting location for the  
antenna unit keep in mind the following  
points:  
Screws  
(one screw on other side)  
Flat washer  
Flat washer  
Spring washer  
Hexagon head bolt  
(M10 x 20)  
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.  
Antenna unit, showing location of  
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.  
In order to minimize the chance of picking  
up electrical interference, avoid where  
possible routing the antenna cable near  
other electrical equipment onboard. Also,  
avoid running the cable in parallel with  
power cables.
