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 the PowerPAC. This is
because the power supply in the equipment does not
adequately filter the modified sine wave produced by the
PowerPAC inverter. Unless the stereo can be operated
directly from the PowerPAC’s 12 volt DC Power Socket,
the only solution is a sound system with a higher quality
internal power filter.
5.4.2 Television Interference
The PowerPAC’s AC inverter 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 the PowerPAC as far
away as possible from the television, antenna and
cables.
2. Adjust the orientation of the PowerPAC, 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.
