Storage & Prevention Tips; General Troubleshooting - VEXILAR FL-8 SE Owner's Manual

Storage & Prevention Tips
● Store in cool dry area. Do not store
in a sealed container like a bucket
or Soft Pack, trapping moisture.
● Be sure an SLA battery is fully
charged before storage.
● Clean the flasher body and screen
with a soft cloth and a mild
detergent. Do not submerge in
water or other liquids.
● Do not expose the body or display
to chemicals such as fish attractant
or insect repellent. Damage to the
surfaces can occur.
● Do not submerge the body in
water or subject it to heavy wave
splashing. The flasher housing is
weather-proof for most conditions,
but is not waterproof. Water
damage is not covered
74
under the warranty.

General Troubleshooting

and motor is not running.
Unit is turned on and the motor is
running, but there is no display.
Unit runs well for a short time, then
lights flash randomly or unit quits.
Unit runs and shows display light,
but does not read depth.
Unit works, but needs high gain to
see bottom or targets.

on the display. Can't distingush
signal targets.

Possible Cause
Check for bad connections, proper hook up polarity, and
make sure you have a good, fully-charged battery.
Battery voltage too low. The unit will show no display if the
voltage is below 8 volts. Check voltage while unit is running.
Bad battery or connection. Voltage may be good when
checked, but will fall as unit runs.
Transducer is not plugged in or not in contact with the water.
Transducer is not aimed correctly or needs to be cleaned.
19° transducers will have trouble seeing small targets deep.
Improper transducer adjustment. Also, gain may be set too
high or, if gain is set to minimum, switch to the LP Mode.
Improper transducer type, installation, or adjustment causing
loss of clear water flow across the transducer when the boat
reaches a certain speed.
Defective engine or electric motor. Also can be improper
grounding or missing ground in electrical system.
Gain may be set too high or the transducer is weak. Also,
check for ice or debris buildup under the Gain Control.
