Never leave the unit in a closed car or trunk - the extremely high temperatures
generated in hot weather can damage the electronics.
Trouble
Many requests for repair received by
LUCKY
involve units that do not actually need
repair.
1.Nothing happens when I turn the unit on.
1)Check the power cable connection. Be sure the cable is connected correctly to a
reliable power ”and“-”.
2)Check the power connection to the FF918. It is possible to force the power cable
connector into the cable holder incorrectly. If the connector is reversed, the unit will
not work. Examine the contacts on the back of the unit to ensure there is no corrosion.
2.There is no transducer detected.
The FF918 has the ability to detect and identify that a transducer is connected. When
powering on, make sure that an appropriate transducer connector is plugged into the
unit. In addtion, inspect the transducer cable from end to end for breaks, kinks, or cuts
in the outer casing of the cable. Also make sure that the transducer is fully submerged
in water. If the transducer is connected to the unit through a switch, temporarily
connect it directly to the unit and try again. If none of these action identifies an
obvious problem, the transducer itself is probably at fault. Be sure to include the
transducer if returning the unit for repair.
3.There is no bottom reading visible on the display.
In very deep water, it may be necessary to increase the sensitivity setting manually to
maintain a graphic depiction of the bottom. Inspect the transducer cable from end to
end for breaks, kinks, or cuts in the outer casing of the cable. If none of these actions
identifies an obvious problem, the transducer itself may be at fault. Be sure to include
the transducer if returning the unit for repair.
4.When in very shallow water, I get gaps in the bottom reading and inconsistent digital
depth indication.
The FF918 will work reliably in water 3 feet (1 meters) or deeper. Remember that the
depth is measured from the transducer, not from the surface of the water.
5.The unit comes on before I press the POWER-MENU key, and won't turn off.
Check the transducer cable – if the outer jacket of the cable has been cut and the
cable is in contact with bare metal, you will need to repair the cut with electrical tape.
If these is no problem with the cable, disconnect the transducer from the unit and see
if the problem is corrected.
6.The display begins to fade out. Images are not as sharp as normal.
Check the input voltage. The FF918 will not operate on input voltages below 10 VDC.
7.The display shows many black dots at high speeds and high sensitivity settings.
