6.2 How to Adjust the Gain
You can adjust the gain (sensitivity) of the radar receiver. The correct setting shows
some background noise on the screen. If you do not use enough gain, weak echoes
are erased. If you use more gain than necessary, the background noise hides both
weak and strong targets.

1. Select [Radar Adjust] from the RotoKey menu.
2. Select [Auto Gain].
Manual gain adjustment
1. Select [Radar Adjust] from the RotoKey menu.
2. Select [Manual Gain].
Note: If [Auto Gain] is checked, first deselect [Auto Gain].
3. Drag the circle icon to set the level (see the figure below).
[RADAR] side menu

with the [RADAR] side menu at the left or right side of the screen. You can also man-
