Vertical menu description

TVG LEVEL: Compensates for propagation loss of sound in water. The default setting is
4.0.
TVG DISTANCE: As above. Default setting is 4.0.
RES. COLOR: Sets transfer characteristics of input signal level versus display echo level.
Echo strength is emphasized in order of CUBE, SQUARE, LINEAR, LOG. You can see the
characteristics of each by watching the color bar as you change the setting. Default setting
is LOG.
LOG: Displays weak to strong echoes in their respective levels. This setting is suitable
for general use.
LINEAR: Downplays the weak echoes when compared with LOG. Effective for suppressing
weak echoes such as plankton.
SQUARE: Strong echoes are emphasized more than in LINEAR.
CUBE: Strong echoes are emphasized even more than in SQUARE.
CLUTTER: Low intensity echoes, often caused by sediments in water, are painted on the
screen as a large number of random dots. The higher the number (setting) the weaker the
echoes which are erased.
