17-6-2 Changing the gain level
Use the radar gain level to adjust the sensitivity of the
radar receiver. Ideally, the radar gain level should be
set so that background noise is just visible on the radar

If the radar gain level is too low, weak echoes won’t be
shown. If the radar gain level is too high, strong echoes
will be difficult to see amongst the large amount of
background noise.
(If the radar Gain Mode is set to Auto and you adjust
the gain level manually, the Gain Mode is changed to
Manual.)
