1. The FF718Li -W loses signal in wireless User Mode.
If the FF718Li -W, while in Wireless user mode, is not able to get an RF signal from the
Wireless sonar sensor, the display will stop updating and the NO SINGAL will be displayed
after several seconds. Whenever reception is lost or the Wireless sonar sensor pulled out from

will be displayed until the Wireless sonar
sensor is placed back in the water and reception is regained.
the water for more than a few seconds, the
1) The Wireless sonar sensor uses line -of-sight wireless technology. If objects are placed
between the FF718Li -W and the Wireless sonar sensor, reception may be lost.
2) The Wireless sonar sensor depth range is 2 to 147 feet (0.7 to 45 meters). Erratic readings
may occur in water that is shallower than 2 feet. In addition, because of the nature of sonar,
this product is not intended for use in swimming pools or small enclosed bodies of water.
3) Reeling the Wireless sonar sensor too fast can cause loss of signal and the screen will freeze.
C
4) Check the buoyant balance between the Wireless sonar sensor and your tackle; over 0.2
ounce will submerge the Wireless sonar sensor, causing signal loss.
5) The Wireless sonar sensor may not obtain its maximum RF distance of 590 feet unless the
water is smooth. Waves or chop may reduce the RF range significantly.
2. When in very shallow water, I get gaps in the bottom reading and inconsistent digital depth
indication.
The Wireless sonar sensor will work reliably in water 2 feet (0.7 meters) or deeper. The depth
is measured from the Wireless sonar sensor.
A Wireless sonar sensor to FF718LiC-W distance of greater than 590ft 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.
