Buzz in Audio Systems

Some stereo systems will emit a buzzing noise from their loudspeakers when

operated from the power inverter because the power supply in the device does

not adequately ﬁlter the modiﬁed sine wave produced by the power inverter.

The only solution is to use a sound system that incorporates a higher quality

power supply.

Operating a Television

Picture tubes have a degaussing coil that uses a high initial surge of power

to light up the screen from a “cold start.” If the television does not start up on

the ﬁrst try, switch on the TV every 2 to 3 seconds until the screen comes on.

Sometimes it may take 2 to 5 tries before starting.

Television Interference

Operating the power inverter can interfere with television reception on some

channels. If this situation occurs, the following steps may help to alleviate the

problem:

1. Make sure the chassis ground lug on the back of the power inverter is

solidly connected to the ground system of the vehicle.

2. Do not operate high power loads with the power inverter while watching

television.

3. Make sure the antenna feeding your television provides an adequate,

“snow free” signal and that you are using a good quality cable between

the antenna and the television.

4. Move the television as far away from the power inverter as possible.

5. 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 the radiated interference from the cables.
