MAINTENANCE
Very little maintenance is required to keep the inverter operating properly.
Keep it clean and dry.
TROUBLESHOOTING
Buzz in Audio Systems
Some stereo systems and boom boxes will emit a buzzing noise from their
loudspeakers when operating with a power inverter. 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 TV does not start up on the first
attempt, try switching the TV on and off consecutively every 2 to 3 seconds
(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:
•
Make sure that the chassis ground lug on the back of the power
inverter is solidly connected to the ground system of your vehicle.
•
Do not operate high power loads with the power inverter while
watching television.
•
Make sure that the antenna connected to your television provides an
adequate static-free signal and that you are using a good quality
cable between the antenna and the television.
