Process mode: C1, C2, C3
The effect to suppress the sea and rain/snow clutter will be stronger in the order of C1 < C2 < C3.
Process mode: A1, A2
A2 mode will display the hardly distinguished target of video signal for a long time than A1 mode.
Note:
• For confirmation of an image that may be hidden between the waves and the image of a fast ship that
appears at a different position for each scan, the image may be displayed weaker than the actual one.
Therefore, when fast moving target on the display, select [PROCESS] OFF.
• For operation of GAIN, SEA and RAIN, it may take some time before it becomes effective. Take
enough time for the operation, or operate again after [PROCESS] has been once off.
• Echo process mode requires heading signal and speed signal, echo process mode turns into OFF if
heading signal or speed signal is unavailable.
