Television and Audio Suggestions
Although these inverters are shielded and filtered to minimize signal interference, some
interference with your television picture may be unavoidable, especially with weak signals.
However, here are some suggestions that may improve reception.
1. First, make sure that television antenna produces a clear signal under normal operating
conditions. Also, ensure that the antenna cable is properly shielded and of good quality.
2. Change the positions of the inverter, antenna cables and television power cord.
3. Isolate the television, its power cord and antenna cables from the 12 volt power source by
running an extension cord from the inverter to the television set.
4. Coil the television power cord and the input cables running from the 12 volt
power source to the inverter.
5. Attach a "Ferrite Data Line Filter" to the television power cord. More than one filter may be
required. These filters are available at most electronic supply stores.
Note:
z Inexpensive sound systems may emit a "buzzing" sound when operated with the inverter.
This is due to inadequate filters in the sound system. There is no solution to this problem
short of purchasing a sound system with a higher quality power supply.
Operating a Microwave oven with Your Power Inverter
The power rating used with microwave ovens is the "cooking power" which qualifies as the
power being "delivered" to the food being micro waved. The actual operating power
requirement rating is higher than the cooking power rating. This is usually referenced on
the back of the microwave. If the operating power requirement cannot be found on the back of
the microwave, check the owner's manual or contact the manufacturer.
Safety Precautions.
For best results place the power inverter on a reasonably flat surface.
z Keep the inverter dry. Do not expose it to rain or moisture.
DO NOT operate the inverter if the inverter, device being operated or any other surfaces
that may come in contact with any power source are wet. Water and many other liquids can
conduct electricity, which may lead to serious injury or death.
z Avoid placing the inverter on or near heating vents, radiators or other sources of heat. Do
not leave the inverter in the passenger compartment of your vehicle. Store in a cool dry
place. Do not place the inverter in direct sunlight. Ideal air temperature should be between
50°F and 80°F.
z In order to properly disperse heat generated while the inverter is in operation, keep it well
ventilated. While in use, maintain several inches of clearance around the top and sides of
the inverter.
z Do not use the inverter near flammable materials. Do not place the inverter in areas such
as battery compartments where fumes or gases may accumulate.
