Buzzing in audio systems and radios

Some inexpensive stereo systems and AM-FM radios have inadequate internal

power supply filtering and “buzz” slightly when powered by the power pack.

Generally, the only solution is an audio product with a higher quality filter.

Television interference

The power pack is shielded to minimize its interference with TV signals.

However, with weak TV signals interference may be visible in the form of lines

scrolling across the screen. The following should minimize or eliminate the

problem:

• Increase the distance between the inverter and the TV, antenna and cables.

• Adjust the orientation of the inverter television, antenna and cables.

• Maximize TV signal strength by using a better antenna and use shielded

antenna cable where possible.

WARNING: Electric shock hazard

Do not remove the cover of the unit or disassemble. The unit does not contain

any internal user-serviceable parts and attempting to service the unit yourself

could result in electrical shock or burn.
