Troubleshooting
Common Audio Problems
Problem
Possible Solution
Buzzing Sound In
Audio Systems
Some inexpensive stereo systems and
boom boxes make a buzzing sound when
operated from the inverter, because the
power supply in the electronic device does
not properly filter the modified sine wave
produced by the inverter. The only solution
to this problem is to use a sound system
that has a higher quality power supply.
Television
Interference
The inverter is shielded to minimize
interference with TV signals. However, in
some instances, some interference may
still be visible, especially when the TV signal
is weak. Try the following to improve the
picture:
1. Move the inverter as far away as
possible from the TV set, the antenna,
and the antenna cables. Use a short
AC extension cord, if necessary.
2. Adjust the orientation of the antenna
cables, and the TV power cord to
minimize interference.
3. Make sure that the antenna feeding the
TV provides an adequate (snow-free)
signal and that high quality, shielded
antenna cable is used.
Common Power Output Problems
Problem
Possible Solution
Input voltage below
10.5 volts
Recharge auto battery or check DC power
supply.
Equipment being
operated draws too
much power
Reduce load to maximum 140 watts for
20 minutes, 120 watts for 60 minutes, 100
watts continuous.
Inverter in thermal
shutdown condition
Allow inverter to cool down. Ensure there
is adequate ventilation around the unit and
that the load is no more than 100 watts for
continuous operation.
AC output is
shorted
Unplug the AC appliance. Disconnect the
unit from any 12 volt DC power source.
Check the appliance cord.
