Common Problems

22

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.

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.
