5. Turn the device on. The display will now show the total wattage used by the
device. To change the digital display, press the ON/OFF switch.
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 inverters Continuous Operation wattage rate.
If there is a short circuit or power surge in the device,  will display
and the alarm will sound. Press the ON/OFF switch to turn off the alarm. If 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 120-volt 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 12-volt power source.
If you are using the power inverter to operate a battery charger,
