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.
Normally, use the automatic tune mode.
Use the manual tune mode only when best tuning is not
possible in the automatic tune mode due to deterioration of
magnetron.
If the gain is too high, unnecessary signals including
receiver noise and false video increase resulting in
reduction of visibility of targets.
On the contrary, if the gain is too low, targets including
ships and dangerous objects may not be clearly indicated.
When using the sea clutter suppression 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 sea clutter suppression function, make
sure to choose the most appropriate image noise
suppression level.
When using the rain / snow clutter suppression 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 rain / snow clutter suppression function,
make sure to choose the most appropriate image noise
suppression level.
