USING THE USB PORT
The USB port provides up to 2.0A at 5V DC.
1. Plug the device into the USB port.
2. Press and hold the ON/OFF switch to turn the inverter on. (The internal
speaker will make a brief "beep". This is normal.)
3. Turn the USB device on.
4. Reverse these steps when finished using the USB port.
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.

6. 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.
If you decide to use the inverter while the engine is off, we recommend you turn
OFF the device plugged into the inverter and disconnect the inverter's plug from
the 12 volt accessory outlet before starting the engine. To maintain battery power,
