System Options
The System Options menu allows the adjustment of several additional features. These adjustments are
usually made initially, and rarely thereafter. To make these adjustments, first enter the System Options
full screen menu with the ENTER key. Then press MENU to choose the category for adjustment, the UP
and DOWN arrow buttons to adjust the setting, and the ENTER key to return to the normal screen when
you have finished.
Scroll Rate controls the rate of update of the display.
There are five rate settings available. The default setting is
rate 4 - you may speed up or slow down the update rate to
match your personal preference. To present the most
accurate representation of the terrain beneath your boat,
the scroll rate of the display should be approximately
synchronized to the speed of the boat. If your boat is
stationary or moving slowly, select a slower scroll rate, and
if you typically operate the boat at high speeds, use a
faster scroll rate. At depths exceeding 600' the scroll rate
may automatically decrease due to the time it takes for the
sonar signal to travel down and back to the surface.
Contrast adjusts the display screen for easier viewing under given light conditions. There are 9 contrast
settings available.
