Buzz in audio systems
Some inexpensive stereo systems have inadequate internal power supply filtering and buzz slightly when powered by the XPower 450. The best solution is to use an audio system with a good quality filter.
Television interference
The XPower 450 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:
•Increase the distance between the XPower 450 and the TV, antenna, and cables.
•Adjust the orientation of the XPower 450, 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.
