ble to the auxiliary power switch included in most boat designs. If
that results in electrical interference, or if such a switch is not
available, we recommend connecting direct to the battery and in-
stalling an inline switch. This will let you shut off power to the
power cable when the unit is not in use. When you are not using
the unit, you should always shut off power to the power cable, es-
pecially when the power cable is disconnected from the unit.

units (direct battery connection shown).
WARNING:
Do not use this product without a 3-amp fuse wired into
the power cable! Failure to use a 3-amp fuse will void
your warranty. This product
must
be independently
fused with the enclosed 3-amp fuse (or equivalent), even
if you connect to a fused accessory or power buss.
If a
malfunction happens inside the unit, extensive damage
can occur if the enclosed fuse is not used. As with all elec-
trical devices this unit could be damaged to a point that
it is unrepairable and could even cause harm to the user
when not properly fused.
If possible, keep the power cable away from other boat wiring, espe-
cially the engine's wires. This will provide the best isolation from elec-
trical noise. If the cable is not long enough, splice #18 gauge wire onto
it.
The power cable has two wires, red and black. Red is the positive lead,
black is negative or ground. Make sure to attach the in-line fuse holder
to the red lead
as close to the power source as possible.
If you have to extend the power cable to the battery or power buss, at-
tach one end of the fuse holder directly to the battery or power buss.
This will protect both the unit and the power cable in the event of a
short. It uses a 3-amp fuse. This unit has reverse polarity protection.
