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.
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.
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.
