JRC JMA-610 Series Instruction Manual page 9

CAUTION
When using the [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 [SEA] function, make sure to choose
the most appropriate image noise suppression level.
When using the [RAIN] function, never set the
suppression level too high canceling out all image
noises from the rain or snow at the close range.
Detection of not only echoes from the rain or snow but
also targets such as other ships or dangerous objects
will become inhibited.
When using the [RAIN] function, make sure to choose
the most appropriate image noise suppression level.
The accuracy from the vectors are depending on the
accuracy from the (D)GPS sensors.
With longer vectors, the accuracy will be lower.
The vectors are calculated with the situation at that
time. When there will be some changed influence from
wind, water current etc, are not shown before the
vessel is influenced by this.
Do not turn the system off while the display shows
"Copying" in a message area on the bottom center of
the screen in order not to make a flash memory card
damaged.
