Caution:
≥This product is designed to operate with a 12 V DC, negative ground battery system.
≥To prevent damage to the unit, be sure to follow the connection diagram below.
≥Remove approximately 5 mm of protective covering from the ends of the leads before connecting.
≥Do not insert the power connector into the unit until the wiring is completed.
≥Be sure to insulate any exposed wires from a possible short-circuit from the car chassis. Bundle all cables
and keep cable terminals free from touching any metal parts.
≥Remember, if your car has a drive computer or a navigation computer, the data of its memory may be
erased when the battery terminals are disconnected.
