TVG LEVEL: Compensates for propagation loss of sound in water. For further details, see
paragraph 2.11.3.
TVG DISTANCE: Sets distance at which TVG works. For further details, see paragraph
2.11.3.
GAIN ADJUST: Adjust the gain here when there is disparity in gain level between the
main and sub windows.
RES. COLOR: Sets transfer characteristics of input signal level versus display echo level.
Echo strength is emphasized in order of CUBE, SQUARE, LINEAR, LOG, and you can
observe the characteristics of each by watching the color bar as you change the setting.
LOG: Displays weak to strong echoes in their respective levels. This is the default
setting, and 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.
