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.

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. 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.
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 war-
ranty. For corrosion protection in saltwater or high humidity
environments, apply a thin layer of electrical-grade grease to
each end of the fuse before installing it in the fuse holder.
