Possible Solution
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.
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
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.
