Common Problems

WARNING

Do not dismantle the PROwatt 600 Inverter. It does not contain any user-serviceable parts. Attempting to service the unit yourself could result in an electrical shock or burn.

Buzz in Audio Equipment

Some inexpensive stereo systems emit a buzzing noise from their loudspeakers when operated from the PROwatt 600. This occurs because the power supply in the audio system does not adequately filter the modified sine wave produced by the PROwatt. The only solution is to use a sound system that has a higher quality power supply.

Television Reception

When the PROwatt 600 is operating, it can interfere with television reception on some channels. If interference occurs, try the following:

1.Make sure the chassis ground screw on the rear of the PROwatt is solidly connected to the ground system of your vehicle, boat, 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 PROwatt 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 PROwatt as possible.

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