WELL-VENTILATED — Keep the area surrounding the inverter clear to ensure free air circulation around the unit. Do not place items on or over the inverter during operation. The unit will shut down if the internal temperature gets too hot.

SAFE — Do not use the inverter near flammable materials or in any locations that may accumulate flammable fumes or gases. This is an electrical appliance that can briefly spark when electrical connections are made or broken.

Notes on Using the Remote Control (sold separately)

For ease of use, Vector offers (as a separate item) a Remote Control specifically designed for this line of MAXX SST inverters. The inverter ON/OFF Switch must be in the OFF position when connecting the Remote Control to the unit or the Remote Control will not operate. Once the unit has been turned ON using the Remote Control, inverter operation will continue to be controlled through the Remote Control. Turn the inverter OFF before disconnecting the Remote Control.

For more information about attaching and using the Remote Control, please refer to the Remote Control User’s Manual.

TROUBLESHOOTING

Common Audio/Visual Problems

Problem	Solution
“Buzzing” sound in audio	Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from
systems	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 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 the antenna feeding the television provides an adequate (“snow
		free”) signal and that high quality, shielded antenna cable is used.
	•	Do not use the inverter to operate high-power appliances or tools at the same
		time you are using it to operate the TV.
	•	Make sure the inverter’s case is properly grounded (refer to the “Permanent
		Installation Procedure” section of this Instruction Manual).
