The depth is measured from the Wireless sonar sensor. A Wireless sonar sensor to FF1108-CWLA
distance of greater than 200ft may cause intermittent screen display. Excessively rough water
may cause the Wireless sonar sensor to submerge, again losing contact.
3. The display shows fluctuating depth readings and excessive clutter, including vertical bars that may
be drawn on top of fish icons.
4. The screen jumps and the bottom has an abrupt change sometimes a vertical line is missing or
a black line from top to bottom is displayed.This screen image jump is due to an automatic change in
depth. New returns graphed at a different scale will not match up with the historic data already
graphed at a higher or lower scale. Vertical lines can also occur as the radio signal from the
Wireless sonar sensor is lost and then regained in rough water conditions.
