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 to 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:

• 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 feeding your television provides an

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

between the antenna and the television.

• 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 2 to 3 twists per foot. This

minimizes radiated interference from the cables.

MAINTENANCE

Very little maintenance is required to keep the inverter operating properly.

HEAT DISPERSAL

The inverter generates heat while it is working. This is not a malfunction.

However, if the inverter gets too hot while working it will turn off by itself.

Position the inverter where air ﬂows freely around it to allow the heat to

disperse. The inverter’s thermal protection prevents it from operating when its

temperature exceeds 130ºF ± 10º (55ºC ± 5º).

TROUBLESHOOTING

Condition Solution

Poor contact Clean contact parts thoroughly

Battery voltage is too low Start the engine to recharge the

battery. Replace the battery if

needed.

Shutdown on overload Reduce the inverter’s wattage load

Thermal shutdown Allow the inverter to cool down by

reducing the load or turning it off for

a while.

Receptacle has no power Check the receptacle wiring.
