7. Troubleshooting

7.1 Common problems
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:
•
Make sure that the chassis ground lug on the back of the power inverter is solidly
connected to the ground system of your vehicle, boat or home.
•
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
TV.
•
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 two to three twists per foot. This minimizes
radiated interference from the cables.

8. Maintenance

Very little maintenance is required to keep your inverter operating properly. You should
clean the exterior of the unit periodically with a damp cloth to prevent accumulation of
dust and dirt. At the same time, tighten the screws on the DC input terminals.
