PRECAUTIONS
vii
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.
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.
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.
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.
Use the radar only as a navigation aid.
The final navigation decision must always be made by the operator
him/herself.
Making the final navigation decision based only on the radar display may
cause accidents such as collisions or running aground.
Use the target tracking function (TT) only as a navigation aid.
The final navigation decision must always be made by the operator
him/herself.
Making the final navigation decision based only on the target tracking
function (TT) information may cause accidents.
The target tracking function (TT) information such as vector, target
numerical data, and alarms may contain some errors. Also, targets that are
not detected by the radar cannot be acquired or tracked.
Making the final navigation decision based only on the radar display may
cause accidents such as collisions or running aground.
When a large value is set as an association condition, a tracked target near
an AIS target is identified as the AIS target and may thus disappear from the
display.
For example, when a pilot vessel equipped with the AIS function (a small
target which is not a tracked target) goes near a cargo vessel which is a
tracked target without the AIS function, the tracked target symbol for the
cargo vessel may disappear.
