Change of the colour
of the Day/Night button, particularly the use of the
[Night] colour, may interfere with the recognition of display information.
Confirm display information can be recognised.
When moving the dialogue box, move to the position that does not cover the
operation area. If the dialogue box covers the operation area, it may interfere
the recognition of the display information.
In the short distance range, do not set the sea clutter suppression function so
that all reflections from the sea are suppressed. This suppresses not only the
echo from waves, etc., but also the echo from floating objects such as ships
or dangerous objects, etc., and obstructs their detection.
When using the sea clutter suppression function, always make the best
suppression setting.
Do not set the rain/snow clutter suppression setting to an excessive level,
because not only the echo from rain or snow but also the echo from floating
objects such as ships or dangerous objects, etc., and obstructs their
detection.
When using the rain/snow clutter suppression function, always make the best
suppression setting.
When setting a guard zone, make sure to properly adjust gain, sea-surface
reflection suppression level, and rain/snow reflection suppression level so
that the op
timal target images are always on the radar screen. The guard
zone alarm will not be activated for targets undetected by the radar, and it
may result in accidents such as collisions.
Since these alarms may include some errors depending on the target tracking
conditions, the navigation officer himself should make the final decision for
ship operations such as collision avoidance.
Making the final navigation decision based only on the alarm may cause
accidents such as collisions.
Do not turn off the power during Backup/Restore.
Otherwise, a function may fail, and an accident may occur.
Do not turn off the power supply during recovery of C drive image.
Otherwise, a function fault occurs, causing an accident.
Specify the power source type, taking into account the ship's mains. In the
case of using the ship's mains of 440VAC, it may be necessary as a
step-down transformer. Improper order or
using may result in a fire or
accidents.
