3.3.9 In the event of rain or snow
CAUTION
Refrain from setting the rain and snow clutter suppression function needlessly.
Doing so may suppress echoes from targets such as other vessels for hazardous
objects in addition to echoes from rain and snow thus impairing detection.
When using the rain and snow clutter suppression function, ensure that the
suppression setting is always at an optimal level.
When rain or snow falls, echo from the rain or snow (rain clutter) appears on the PPI
screen making it difficult to see images of echoes from vessels or other objects.
By using the [RAIN] control function or the "automatic rain and snow" function, rain
clutter may be suppressed facilitating monitoring of the target.
When the "automatic rain and snow" function is operating, it is not possible to use the
[RAIN] control function.
