Operating Instructions - Schumacher Electric PI-750 Owner's Manual

6. OPERATING INSTRUCTIONS

1. Connect the inverter (see Connecting Inverter Cables section).
2. Make sure the device to be operated is turned OFF.
3. Plug the device into the inverter's AC outlet.
4. Switch the inverter's ON/OFF switch to the ON position.
5. Turn the device on.
6. To disconnect, reverse the above procedure.
NOTE: If more than one device is to be powered, start one device at a time to avoid a
power surge and overloading the inverter. The surge load of each device should not
exceed the inverter's Continuous Operation wattage rate.
USING THE INVERTER TO OPERATE A TV OR AUDIO DEVICE:
The inverter is shielded and filtered to minimize signal interference. Despite this, some
interference may occur with your television picture, especially with weak signals. Below
are some suggestions to try and improve reception.
1. Try altering the position of the inverter, antenna cables, and television power
cord. Add an extension cord from the inverter to the TV, to isolate its power
cord and antenna cables from the 12 volt power source.
2. Try coiling the television power cord and the input cables running from the 12
volt power source to the inverter.
3. Affix one or several "Ferrite Data Line Filters" to the television power cord. Ferrite
Data Line Filters can be purchased at most electronic supply stores.
4. Try grounding the inverter with an 18 AWG (minimum) wire, using as short a
length as possible.
NOTE: You may hear a "buzzing" sound being emitted from inexpensive sound
systems when operated with the inverter. This is due to ineffective filters in the
sound system's power supply. Unfortunately, this problem can only be resolved by
purchasing a sound system with a higher quality power supply or higher quality filter.
WARNING: The inverter draws power, even when the switch is OFF. To avoid
battery drain, disconnect the inverter when not in use.
