NOTE
The audible alarm may make a momentary chirp when the inverter is turned OFF (O). This
same alarm may also sound when the inverter is being connected to or disconnected from
the 12V power source. When using an extension cord from the inverter to the appliance
the extension cord should be no more than 50 feet long. At this length there should be no
measurable decrease in power from the inverter.
TELEVISION AND AUDIO SUGGESTIONS
Although all PowerBright™ inverters are shielded and filtered to minimize signal interference,
some interference with your television picture may be unavoidable, especially with weak
signals. However, here are some suggestions that may improve reception.
1. First, make sure that the television antenna produces a clear signal under normal
operating conditions. Also, ensure that the antenna cable is properly shielded and of
good quality.
2. Change the positions of the inverter, antenna cables and television power cord.
3. Isolate the television, its power cord and antenna cables from the 12V power source by
running an extension cord from the inverter to the television set.
4. Coil the television power cord and the input cables running from the 12V power source
to the inverter.
5. Attach a Ferrite Data Line Filter to the television power cord. More than one filter may be
required. These filters are available at most electronic supply stores.
NOTE
Some inexpensive audio systems may discharge a slight buzzing sound when operated with
the inverter. This is caused by deficient filters in the audio system. The only solution to this
problem is using a sound system with a higher quality power supply.
