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, 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
