3 Troubleshooting

Chapter 3 will help you identify the source of most problems that can occur with the XPower 1500.

If you have a problem with the inverter, please review this chapter before contacting your dealer.

If you are unable to solve a problem and need to contact your dealer, record the details on the form “Information About Your System” on page WA–4.

Common Problems

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 XPower 1500. This is because the power supply in the equipment does not adequately filter the modified sine wave produced by XPower 1500. Unless the stereo can be operated directly from XPower 1500’s 12-volt DC Power Socket, the only solution is a sound system with a higher quality internal power filter.

Television Interference

XPower 1500 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 XPower 1500 as far away as possible from the television, antenna, and cables.

2.Adjust the orientation of XPower 1500, 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.
