5.4 Interference with Electronic Equipment
5.4.1 Buzzing Sound in Audio Systems
Some inexpensive stereo systems and boom-boxes will emit a
buzzing sound from their loudspeakers when operating from the
AC output of xPower600. This is because the power supply in the
equipment does not adequately filter the modified sine wave
produced by xPower600. Unless the stereo can be operated
directly from xPower600s 12 Volt DC Power Socket, the only
solution is a sound system with a higher quality internal power
filter.
5.4.2 Television Interference
xPower600 is shielded to minimize interference with TV signals.
In some cases, particularly with weak TV signals, some interference
may still be visible in the form of scrolling lines across the screen.
In this case, take the following corrective measures:
1. Use an extension cord to position xPower600 as far away as
possible from the television, antenna, and cables.
2. Adjust the orientation of xPower600, television, antenna, and
cables to minimize interference.
3. Maximize TV signal strength by using a better antenna, and
ensure a shielded antenna cable is used.
4. Try a different TV. Different models of TV sets vary greatly in
their susceptibility to interference.
