4.3.4. Gain Control
(1) How to control Gain Control
Turn
to the left to decrease the Gain and to the right to increase the Gain.
(2) To adjust the optimum gain
The echo image size by target is the biggest and any targets nearby do not contact the echo image.

4.3.5. Rain/Snow Removal
(1)
If much rain/snow, it is difficult to analyze the wishful target image as the echo by rain/snow clutter
appears on the PPI display.
(2) Turn
(rain/snow) to the right to remove the echo image by snow and rain.

ATTENTION
※
It should be always observed by adjusting the optimum conditions.
※
If the gain is too low, the targets may not be displayed.
※
If too high, it may be an obstacle in observation due to the noise increase on the
PPI display.
ATTENTION
※
Too much adjustment of rain/snow removal will restrain the target of ships or
hazards as well as any images by rain/snow. This can be the cause of image
analysis.
※
In case of use of rain/snow removal, the optimum conditions should always set up.
