Caution
A malfunction may occur if the power in the
ship is instantaneously interrupted during
operation of the radar. In this case, the power
should be turned on again.
Attention
z Wait for about 2 seconds before turning on the
power again.
z Immediately after the radar is installed, at start of the
system after it has not been used for a long time, or
after the magnetron is replaced, preheat the
equipment in the standby state for 20 to 30 minutes
before setting it into the transmit state.
z If the preheating time is short, the magnetron
causes sparks, resulting in its unstable oscillation.
Start transmission on a short-pulse range and
change the range to the longer pulse ranges in turn.
If the transmission is unstable in the meantime,
immediately place the system back into the standby
state and maintain it in the standby state for 5 to 10
minutes before restarting the operation.
Repeat these steps until the operation is stabilized.

Control Sensitivity [GAIN/PL]
Caution
If sensitivity is set too high, unnecessary signals such
as noises in the receiver and false echoes increase to
lower target visibility.
At the same time, if sensitivity is set too low, detection
of targets such as ships and dangerous objects may be
hindered.
Therefore, sensitivity must always be set to an optimal
level.
Procedure
Control noise on the radar display by turning the [GAIN/PL] control until
targets can be easily observed.
Turning [GAIN/PL] control clockwise increases sensitivity.
Turning [GAIN/PL] control counterclockwise decreases sensitivity.
Turning the [GAIN/PL] control clockwise increases receiving sensitivity and extends the radar
observation range. If the sensitivity is too high, the receiver noise increases reducing the
contrast between the targets and the background video. As a result, the targets become
obscure on the radar display.
To observe densely crowded targets or short-range targets, turn the [GAIN/PL] control
counterclockwise to reduce the sensitivity so that the targets are easy to observe. However,
be careful not to overlook important small targets.

Caution
When using the [AUTO SEA] function, never set the
suppression level too high canceling out all image
noises from the sea surface at close range.
Detection of not only echoes from waves but also
targets such as other ships or dangerous objects will
become inhibited.
When using the [AUTO SEA] function, make sure to
choose the most appropriate image noise suppression
level.
When using the manual sea clutter suppression function
Procedure
Control the sea clutter returns on the radar display by turning the
[AUTO-SEA] control until targets can be easily observed.
Turning [AUTO-SEA] control clockwise suppresses sea clutter returns.
Turning [AUTO-SEA] control counterclockwise intensifies sea clutter returns.
The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving
sensitivity on a short range.
Turning the [AUTO-SEA] control clockwise heightens the effect of sea clutter suppression.
However, be careful that excessive suppression causes low signal-strength targets such as
buoys and boats to disappear from the radar display.
Using AUTO SEA (automatic sea clutter suppression function)
Sea clutter suppression can be performed in accordance with the level of sea clutter. Use this
function when the clutter level changes with the direction.
Procedure
Press the [AUTO-SEA] control.
AUTO SEA is selected, and SEA AUTO is indicated at the lower left of the radar

Suppress Rain/Snow Clutter [AUTO-RAIN]
Caution
When using the [AUTO RAIN] function, never set the
suppression level too high canceling out all image
noises from the rain or snow at the close range.
Detection of not only echoes from the rain or snow but
also targets such as other ships or dangerous objects
will become inhibited.
When using the [AUTO RAIN] function, make sure to
choose the most appropriate image noise suppression
level.
When using the manual rain/snow clutter suppression function
Procedure
Control the rain/snow clutter returns on the radar display by turning the
[AUTO-RAIN] control until targets can be easily observed.
Turning [AUTO-RAIN] control clockwise suppresses rain/snow clutter returns.
Turning [AUTO-RAIN] control counterclockwise intensifies rain/snow clutter returns.
When the [AUTO-RAIN] control is turned clockwise, the rain/snow clutter suppression
function suppresses rain/snow clutter returns and gets targets hidden by rain/snow clutter
returns to appear on the radar display. However, be careful that excessive suppression may
cause small targets to be overlooked. Since the rain/snow clutter suppression function also
has the effect of suppressing sea clutter, the suppression efficiency improves when the
[AUTO-RAIN] control is used with the [AUTO-SEA] control. In general, turn the
[AUTO-RAIN] control fully to the left.
Using AUTO RAIN (automatic rain/snow clutter suppression function):
Rain/snow clutter suppression can be performed in accordance with the level of rain/snow
clutter. Use this function when the clutter level changes with the direction.

True Bearing Mode [North Up]
The video is displayed so that the zenith of the PPI (0° on range rings) points to the due north. Fixed
targets do not flicker and are easily identified on the chart, and the true bearing of a target can easily
be read out.
Relative Bearing Mode [Head Up]
The video is displayed so that the ship’s heading line points to the zenith of the PPI (0° on range
rings). Since targets are displayed in their directions relative to the ship’s heading line, the operator
can view the video in the same field of view as in operating the ship at sea. This mode is suitable for
watching over other ships.
Course-up Bearing Mode [Course Up]
By pressing [AZI MODE] key, the own ship’s course is fixed pointing to the zenith of the PPI (0° on
range rings) points to the due north. In the same way as in the North-up mode, fixed targets do not
flicker, and are stabilized even if the ship is yawing. The bearing of the heading line varies by the
same shift of own ship’s course. To change the course, press [AZI MODE] key several times to

moving targets move on the radar display. When the true motion mode is selected, the
own ship’s position is set to about 60% of the display radius in the opposite direction to its
course allowing for the influence of the current. Own ship starts moving depending upon
its speed and course and the influence of the current. Subsequently, when own ship
arrives at the position of about 66% of the display radius, it is automatically reset to its
initial position at about 60% of the display radius in the opposite direction to its course
allowing for the influence of the current.
