echoes returned from the
ocean surface. Higher
values suppress more clutter. Sea Clutter
can be set to automatic or manual mode.
Press the activated Sea clutter key to
switch modes. The sea clutter setting can
be entered on the keypad or by using the
cursor pad. Manual settings range from 0
to 214 (0 to 255 on the 2kW unit). Auto-
matic settings range from 0 to 50 (0 to 255
on the 2kW unit) and are unrelated to the
manual setting numbers.
Gain controls the strength
of all echoes, and should be
adjusted for a pleasing and
useful image. Higher values
display brighter echoes. Gain can be set to
automatic or manual mode. Press the acti-
vated Gain key to switch modes. The gain
setting can be entered on the keypad or by
using the cursor pad. Manual settings
range from 0 to 299. Automatic settings
range from 0 to 50 and are unrelated to
the manual setting numbers. (Settings for
the 2kW unit range from 0 to 255). Manual
gain adjustments will be different for each
range scale. Longer ranges generally
require more gain.
If speckling appears on the screen, you
may wish to decrease the gain a bit or
increase the sea clutter setting.
