You can use an extension cord from the inverter to the
appliance without signicantly decreasing the power being
generated by the inverter. For best operating results, the
extension cord should be no longer than 50 feet.
The LED Indicator briefly flashing when you first turn
the inverter ON, is a sign if that there is a short circuit
within the power supply. Turn the inverter OFF. Remove
the 12-volt plug from the cigarette lighter socket. Firmly
re-insert the plug. Turn the inverter ON again. If this
does not remedy the problem try using a different 12-volt
power source.
Using the Inverter to Operate a TV or Audio Appliance
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 110 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 television power
cord. Ferrite Data Line Filters can be purchased at most
electronic supply stores including Radio Shack - Part
