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.
Note:
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.
Power On
1Press the [STBY] key on the display unit to turn on the display unit.

2.4 SENSITIVITY ADJUSTMENT
Sensitivity can be adjusted.
Adjust the noise on the display unit to achieve better observation state.
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.
Noise Adjustment
1Turn the [GAIN] control.
Turn the [GAIN] control clockwise to increase sensitivity.
Turn the [GAIN] control counterclockwise to decrease sensitivity.
The sensitivity adjustment screen appears when turning the [GAIN] control.

INSTRUCTION MANUAL
z [GAIN] Control
Turning the [GAIN] 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] control counterclockwise to reduce the sensitivity so
that the targets are easy to observe. However, be careful not to overlook important small
targets.
Switching to Manual/Automatic Mode

The relative vector does not represent the true motion of the target, but its relative
relation with own ship. This means that a target with its relative vector directed to own
ship (passing through the CPA LIMIT ring) will be a dangerous target.
In the Relative Vector mode, it can be seen at a glance where the CPA LIMIT of the

2.7.7 TT OPERATIONS
The target tracking function calculates the course and speed of a target by automatically
tracking the target's move.
Note:
z There are the following limitations on use of the target acquisition and target
tracking functions.
[I] Resolution between adjacent targets and swapping during automatic target
tracking
Depending on the particular distance and echo size, resolution between
adjacent targets during automatic target tracking usually ranges somewhere
between 0.03 to 0.05 NM. If multiple targets approach each other, resolution will
become about 0.05 NM and this may cause the system to regard them as one
target and thus to swap them or lose part of them. Such swapping or less of
targets may also occur if the picture of the target being tracked is affected by
rain/snow clutter returns or sea clutter returns or moves very close to land.
[II] Intensity of echoes and the target tracking function
The intensity of echoes and the tracking function have a correlationship, and
thus the target will be lost if no echoes are detected during seven scans in
succession.
If a lost target exists, therefore, radar gain must be increased to support
detection of the target. If, however, radar gain is increased too significantly, sea
clutter returns or other noise may be erroneously detected and tracked as a
target, and resultingly, a false alarm may be issued.
To execute accurate tracking, it becomes necessary to appropriately adjust the
[GAIN], [SEA] and [RAIN] controls of the radar so that the target to be acquired
and tracked id clearly displayed on the radar display.
Inappropriate settings of these adjustments reduce the reliability / accuracy of
automatic tracking.

depending upon its speed and course and the influence of the current. Land and other
fixed targets are fixed on the radar screen and only actually moving targets move on the
radar screen. When the true motion display mode is selected, the own ship's position is
set to 66% 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
66% of the display radius, it is automatically reset to its initial position at 66% of the
display radius in the opposite direction to its course allowing for the influence of the
current.
