Buzz in Audio Equipment
Some inexpensive stereo systems emit a buzzing noise from
their loudspeakers when operated from the PROwatt 600.
This occurs because the power supply in the audio system
does not adequately filter the modified sine wave produced
by the PROwatt. The only solution is to use a sound system
that has a higher quality power supply.
Television Reception
When the PROwatt 600 is operating, it can interfere with
television reception on some channels. If interference occurs,
try the following:
1. Make sure the chassis ground screw on the rear of the
PROwatt is solidly connected to the ground system of
your vehicle, boat, or home.
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 PROwatt 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 PROwatt as
possible.
5. Do not operate high power loads with the PROwatt while
the television is on.
WARNING
Do not dismantle the PROwatt 600 Inverter. It does
not contain any user-serviceable parts. Attempting
to service the unit yourself could result in an
electrical shock or burn.
