6. Plug the device into the inverter AC outlet.
7. Turn the inverter on.
8. Turn the device on.
9. 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 so as 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 12V
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) (0.75mm2) 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.

8. POWER SOURCE

Your average automobile or marine battery at full charge will provide an ample power
supply to the inverter for approximately 3 hours when the engine is off. The actual
length of time the inverter will function depends on the age and condition of the battery
and the power demand being placed by the device being operated with the inverter.
Before starting the engine after using the inverter with the engine off, turn OFF the
device plugged into the inverter and disconnect the inverter plug from the 12 volt
accessory outlet. To maintain battery power, start the engine every 2 to 3 hours
and let it run for approximately 30 minutes to recharge the battery.
Although it is not necessary to disconnect the inverter when turning over the engine, it
may briefly cease to operate as the battery voltage decreases. While the inverter draws
very low amperage when not in use, unplug it to avoid battery drain.
