Use these radar only as assisting devices for navigation.
Also, the officer should make the final decision for maneuvering by himself.
If you make the final decision of maneuvering only on the information which a
radar display, it may become the cause of accidents, such as collision and
stranding.
Do not set the rain/snow clutter function to too high a suppression level.
Otherwise, not only echoes from rain/snow but also the targets of ships or
dangerous objects are suppressed, which may disturb the detection.
Set the best suppression level whenever you use the ran/snow clutter
suppression function.
Do not set the sea clutter suppression function to a level at which it clears all
sea clutters in short range.
Otherwise, not only echoes from waves but also the targets of ships or
dangerous objects are suppressed, which may disturb the detection.
Set the best suppression level whenever you use the sea clutter suppression
function.
The scanner unit shall be installed where there are not large obstacles in the
direction of the ship's heading line in the same plane.
If there is a large impediment in the same plane as the scanner unit, this may
cause the generation of folse echoes. In particular, if such folse echoes appear
at the ship's heading line, monitoring will be difficult and this may cause
inadequate forecasting of danger.
Do not install the scanner unit near chimney's or the exhaust of chimneys.
Soot will cause the performance of the radar to decrease and heat may cause
breakdown.
Do not install direction antenna or VHF antenna in the vicinity of the scanner
unit. Doing so may cause noise in the antenna reception.
Consideration should be given to separating the radar cable from the cables for
the direction antenna and VHF antenna.
These cables should never be bundled into one. Doing so may cause noise in
the antenna reception.
