AUTO adjustment of SEA
When AUTO SEA is set, anti-SEA is adjusted automatically.
Note: AUTO SEA may erase weak target echoes. If excessive sea clutter erasing or too much clutter is
observed, turn SEA knob clockwise or counterclockwise to adjust AUTO SEA effectively.
If not setup properly, adjust it by referring to 4.4.3 Setup GAIN MIN and MAX mode of Installation
manual.
In case there are strong echo targets such as in the harbor or canal, anti-SEA tends to suppress
excessively, use MAN SEA in that case.
Manual adjustment of SEA
When MAN SEA is selected, anti-SEA can be adjusted manually.
By using SEA knob, suppress this effect and make targets seen easier.
[SEA] state is displayed in the upper right of the display.

Turn SEA knob clockwise to increase anti-sea clutter effect.
Turn SEA knob counterclockwise to decrease anti-sea clutter effect.

display.

sea clutter changes as time passes.

SEA
Note:
• When waves do not affect the result, turn the knob fully counterclockwise.
• This function reduces gain in closest ranges. Too much sea clutter may result in actual targets being
lost.
• Manual SEA user keep watching and adjusting SEA with changing conditions.
• If SEA and anti-RAIN are used in combination, then small targets will be less visible.
