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.
