Common Problems

Buzz in Audio Equipment

Some inexpensive stereo systems may emit a buzzing noise from their loudspeakers when operated from the Freedom HF. 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.

3.Keep the cables between the battery and the Freedom HF 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 Freedom HF as possible.

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

Television Reception

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

1.Make sure that the chassis ground stud on the Freedom HF is solidly connected to the ground system of your vehicle or vessel.

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.
