Using the Inverter to Operate a TV or Audio Device:

The inverter is shielded and ltered to minimize signal interference. Despite this,

some interference may occur with your television picture, especially with weak

signals. Below are some suggestions to try and improve reception.

Make sure the television antenna produces a clear signal under normal 1.

operating conditions (i.e. at home plugged into a standard 120-volt AC wall

outlet). Also, ensure that the antenna cable is adequately shielded and of

good quality.

Try altering the position of the inverter, antenna cables, and television 2.

power cord. Add an extension cord from the inverter to the TV so as to

isolate its power cord and antenna cables from the 12-volt power source.

Try coiling the television power cord and the input cables running from the 3.

12-volt power source to the inverter.

Afx one or several “Ferrite Data Line Filters” to the television power cord. 4.

Ferrite Data Line Filters can be purchased at most electronic supply stores.

NOTE: You may hear a “buzzing” sound being emitted from inexpensive sound

systems when operated with the inverter. This is due to ineffective lters in the

sound system’s power supply. Unfortunately, this problem can only be resolved by

purchasing a sound system with a higher quality power supply or higher quality lter.

POWER SOURCE6.

Your average automobile or marine battery at full charge will provide an ample power

supply to the inverter for approximately 3 hours when the engine is off. The actual

length of time the inverter will function depends on the age and condition of the

battery and the power demand being placed by the device being operated with the

inverter.

If you decide to use the inverter while the engine is off, we recommend you turn OFF

the device plugged into the inverter before starting the engine. To maintain battery

power, start the engine every 2 to 3 hours and let it run for approximately 10 minutes

to recharge the battery.

Although it is not necessary to disconnect the inverter when turning over the engine,

it may briey cease to operate as the battery voltage decreases. While the inverter

draws very low amperage when not in use, it should be unplugged to avoid battery

drain.
