7.COMMON PROBLEMS
“Buzzing” sound in audio systems:
Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from their speakers when operated from the POWER INVERTER. This occurs because the power supply in the electronic device does not adequately filter the modified sine wave produced by the inverter. The only solution to this problem is to use a higher quality sound system that incorporates a higher quality power amplified supply.
Television Interference:
The Husky POWER INVERTER is shielded to minimize interference with TV signals. However, in some instances, some interference may still be visible, particularly with weak TV signals. Try the following corrective measures:
•Position the inverter as far as possible from the television, the antenna and the antenna cables. Use an extension cable, if necessary
•Adjust the orientation of the inverter, the antenna cables and the TV power cord to minimize interference
•Make sure that the antenna feeding the television provides an adequate (“snow free”) signal and that high quality, shielded antenna cable is used
