Common Problems
Buzz in Audio Equipment
Some inexpensive stereo systems may emit a buzzing noise from their loudspeakers when operated from the inverter. 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 inverter 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 inverter is solidly connected to the ground system of your vehicle.
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 inverter as short as possible, and ensure that the positive and negative cables are run very close to each other. This minimizes radiated interference from the cables.
4.Move the television as far away from the inverter as possible.
5.Do not operate high power loads with the inverter while the television is on.
