CAUTION 
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.
 
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.
 
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.
