Common Problems
Buzz in audio systems
Some inexpensive stereo systems have inadequate internal power
supply filtering and buzz slightly when powered by the Digital Inverter.
The best solution is to use an audio system with a high-quality filter.
Television interference
The Digital Inverter is shielded to minimize interference with TV
signals. If TV signals are weak, you may see interference in the form of
lines scrolling across the screen. Try one of these suggestions to
minimize or eliminate the problem:
• Adjust the orientation of the Digital Inverter, television, antenna,
and cables.
• Maximize TV signal strength by using a better antenna, and use
shielded antenna cable where possible.
• Try a different TV. Different models vary considerably in their
susceptibility to interference.
WARNING: Electrical shock and burn hazard
Do not disassemble the Digital Inverter. It does not contain any user-
serviceable parts. Attempting to service the inverter yourself could result
in an electrical shock or burn.
