5.3.4 Adjusting gain
Be sure to always adjust for the best gain.
If the gain is too high, undesired signals including receiver noise and
false echoes increase resulting in reduction of visibility of targets.
Otherwise, accidents may result.
On the contrary, if the gain is too low, targets including ships and
dangerous objects may not be clearly indicated.
Adjust the gain of the radar.
Memo
Set the optimum gain when making adjustments, giving consideration to the setting described in
"5.3.7 Adjusting to optimal images (Selection of observation scenes)".
