#OLORTHRESHOLD Allows the "weaker" targets and noise which may be shown
on the display screen to be eliminated from the display. These targets are usu-
ally shown in the weaker target colors such as blues and greens. The color
threshold allows you to choose not to display the blues, or the blues and
greens, etc. Doing this will leave only the stronger targets on the display screen.
F The monochrome version will have 3 different tones of grey.
$EPTH Setting the various depth features correctly can have great influence on
the performance of the echosounder. In the ’Echosounder setup’ display ’Max
depth limit’ is preset to AUTO, but can be changed to a specific value if the
depth is known. This will give a faster ping rate. ’Depth for fish’ can be de-
fined to a minimum and maximum depth level if looking for a specific cate-
gory of fish. See also ’Range’ and ’Range start’ further on in this appendix.
%CHOGRAMBACKGROUNDCOLOR Is the screen color shown in the echo displays
in the event no target is present. There are two colors to choose from, white or
black, where black is especially useful during nighttime operation when the
white background could appear too bright.
