the  displays after several attempts, there is a short circuit or the device requires
more "starting" or "peak" load than the inverter is capable of providing.
monitor the temperature of the battery charger for about 10 minutes. If the battery
charger becomes abnormally warm, disconnect it from the inverter immediately.
NOTE: You can use an extension cord from the inverter to the device without
significantly decreasing the power being generated by the inverter. For best
operating results, the extension cord should be no longer than 50 feet.
Using the USB Port
The USB port provides up to 500mA 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. Make sure the television antenna produces a clear signal under normal operating
conditions (i.e. at home plugged into a standard 120V AC wall outlet). Also,
ensure that the antenna cable is adequately shielded and of good quality.
2. 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 12V power source.
3. Try coiling the television power cord and the input cables running from the 12V
power source to the inverter.
4. 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.
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.

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 before starting the engine. To maintain
battery power, start the engine every 2 to 3 hours and let it run for approximately
10 minutes to recharge the battery.
