If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit.

Unit won’t turn on:

1.Check the power cable’s connection at the unit. Also check the wiring.

2.Make certain the power cable is wired properly. The red wire connects to the positive battery terminal, black to negative or ground.

3.Check the fuse.
