3. Avoid locations that are exposed to heating units, radiators, direct sunlight, or excessive humidity or
dampness.
TROUBLESHOOTING
Common Audio/Visual Problems
Problem: 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.
Problem: 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.
Power/Fault LED Indicator Lights Red
When the Power/Fault LED Indicator turns from green (indicating the unit is powered) to red, a fault condition
is present and the unit will automatically shut down. See the Protective Features Section of this Instruction
Manual and Common Power Output Problems in the following section.
