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.
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.
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.
Always use the automatic tuning mode.
Use the manual tuning mode only when the automatic
tuning mode does not provide the best tuning state due
to deterioration of magnetron for example.
