7.0 Troubleshooting

7.1 Common problems

Television interference: Operation of the power inverter can interfere with

television reception on some channels. If this situation occurs, the following steps

may help to alleviate the problem:

 Make sure that the chassis ground lug on the back of the power inverter is

solidly connected to the ground system of your vehicle, boat or home.

 Do not operate high power loads with the power inverter while watching

television.

 Make sure that the antenna feeding your television provides an adequate

"snow free) signal and that you are using good quality cable between the

antenna and the TV.

 Move the television as far away from the power inverter as possible.

 Keep the cables between the battery and the power inverter as short as

possible and twist them together with about two to three twists per foot. This

minimizes radiated interference from the cables.
