with electrical interference. Therefore, it's safer to go ahead and attach
the power cable directly to the battery.
the power cable directly to the battery.
CAUTION:
When using the unit in a saltwater environment, we strongly rec-
ommend that you shut off the power supply to the power cable when
the unit is not in use. When the unit is turned off but still connected
to a power supply, electrolysis can occur in the power cable plug.
This may result in corrosion of the plug body along with the electri-
cal contacts in the cable and the unit's power socket.

In saltwater environments we recommend you connect the power
cable 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.

If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
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. (There is also a white wire to power an optional
external speaker for some units.) Make sure to attach the in-line fuse
holder to the red lead as close to the power source as possible.

For example, if you have to extend the power cable to the battery or
power buss, attach 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.
