S TC
(Sensitivity Time Control) reduces surface clutter by reducing the gain in
the top 30-40 ft of the display: A low
STC
value has little effect on gain in
shallow water; a high
S TC
value decreases the gain in shallow water, thus only
the strongest echoes are displayed.
This function is useful for reducing background noise, caused by air bubbles
and floating debris, that often appears in shallow water.
➤
To adjust a parameter:
1. Press the
GAIN
key, the gain sliders are displayed. The last used slider is
highlighted (displayed in inverse video) to show that it is selected.
2. If necessary on a split frequency display, press the
GAIN ADJUST
soft key to
select the required frequency for adjustment.
Note: On a single frequency display you adjust the gain for the displayed fre-
quency.
3. If necessary, press the required soft key so the slider is highlighted.
Press it again, if necessary, to toggle between
AUTO and MANUAL
adjust-
ment.
4. Use the trackpad to move the slider up or down. You can press and hold the
trackpad to move the slider quickly rather than in single steps.
The image on the screen changes as you move the slider and the value is
indicated in the slider.
Note: Because the changes to the settings are made immediately, you cannot
revert to the previous settings by pressing
CLEAR
.
5. When you have set all the controls to the levels you require, press
ENTER
or
CLEAR
to return to the default display.
