power consumption. When the inverter is oFF, no lights
appear.
Using the Inverter to operate a tV or Audio Device
The inverter is shielded and filtered 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 operating conditions (i.e., at home plugged
into a standard 115V AC wall outlet). Also, ensure that the
antenna cable is adequately shielded and of good quality.
Try altering the positions of the inverter, antenna cables,
and television 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 12 -volt power source to the inverter.
Affix one or several "Ferrite Data Line Filters" to the tele-
vision power cord. Ferrite data line Filters can be pur-
chased at most electronic supply stores including Radio
Shack - Part Number 23-105.
Attention: You may hear a "buzzing" sound being emit-
ted from inexpensive sound systems when operated with
the inverter. This is due to ineffective filters in the sound
system. This problem can only be resolved by purchasing
a sound system with a higher quality power supply.
