Troubleshooting

Common Problems

Buzz in Audio Equipment

Some inexpensive stereo systems may emit a buzzing noise from their loudspeakers when operated from the XPower Plus. This occurs because the power supply in the audio system does not adequately filter the modified sine wave produced by the inverter. The only solution is to use a sound system that has a higher quality power supply.

Television Reception

When the XPower Plus is operating, it can interfere with television reception on some channels. If interference occurs, try the following:

1.Make sure that the chassis ground screw on the rear of the XPower Plus is solidly connected to the ground system of your vehicle or home.

2.Make sure that the television antenna provides an adequate (“snow- free”) signal, and that you are using good quality cable between the antenna and the television.

3.Keep the cables between the battery and the XPower Plus as short as possible, and twist them together with two to three twists per foot. (This minimizes radiated interference from the cables.)

4.Move the television as far away from the XPower Plus as possible.

5.Do not operate high power loads with the XPower Plus while the television is on.
