Gain
This is used to adjust the sensitivity of the receiver. Setting Gain to a
low level will clear up some of the clutter on the screen, but also could
eliminate some desired echoes. A high level of the Gain, allows you to
see greater detail around you, but will clutter the screen.
NOTE:
When adjusting Gain back to a useable level, increase the level un-
til you see a light peppering of echoes on the display. Also remem-
ber, you will have to adjust gain every time you change ranges.
To adjust Gain:
1. Highlight

. That will launch
the Gain vertical scrollbar.
2. Use
↑ ↓ to adjust the Gain to a desired level. Press
EXIT

the scrollbar from the screen.
