Common Problems

Buzz in Audio Equipment

Some inexpensive stereo systems have inadequate internal power-supply filtering and may buzz slightly when powered by the XPower Powerpack. The best solution to eliminate the buzzing is to use an audio system with a good quality filter.

Television Interference

The XPower Powerpack 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 TV screen. Try one of the following suggestions to minimize or eliminate the interference:

•Use an extension cord to increase the distance between the XPower Powerpack and the TV, antenna, and cables.

•Adjust the orientation of the XPower Powerpack, television, antenna, and cables.

•Maximize TV signal strength by using a better antenna. Use a shielded antenna cable where possible.
