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.
• Try a different TV. Different models vary considerably in
their susceptibility to interference.
Troubleshooting Reference
WARNING: Electric shock hazard
Do not remove the cover of the XPower Powerpack or
disassemble the XPower Powerpack except to replace
the internal battery. The XPower Powerpack does not
contain any internal user-serviceable parts and
attempting to service the unit yourself could result in
electrical shock or burn.
