7. Troubleshooting
7.1 Common problems
a) Buzz in audio systems
Some inexpensive stereo systems will emit a buzzing noise from their loud
speakers when operated from the power inverter. This is because the power
supply in the device does not adequately filter the modified sine wave pro
duced by the power inverter. The only solution is to use a sound system that
incorporates a higher quality power supply.
b) Television interference
Operation of the power inverter can interfere with television reception on
some channels. If this situation occurs, the following steps may help to
alleviate the problem.
• Do not operate high power loads with the power inverter while watching
television.
• Make sure that the antenna feeding your television provides an adequate
(“snow free”) signal and that you are using good quality cable between
the antenna and the television.
• Move the television as far away from the power inverter as possible.
• Keep the cables between the battery and the power inverter as short as
possible and twist them together with about 2 to 3 twists per foot. This
minimizes radiated interference from the cables.
