Connecting inverter cable to a vehicle (100 watts maximum):
1. Remove the cigarette lighter from its outlet.
2. Push the 12 volt power plug firmly into the outlet.
Connecting inverter cables to 12V battery or 12V power source:
1. Keep hands, hair, clothing and jewelry clear of battery terminals.
2. Wear eye protection and clothing protection.
3. Connect the positive (red) inverter terminal cable to the power source positive
(+) or battery terminal. Make sure the connection is secure.
4. Connect the negative (black) inverter terminal cable to the power source
negative (-) or battery terminal. Make sure the connection is secure.
5. To disconnect the inverter, reverse the above steps.
NOTE: The internal speaker may make a brief "beep" when the inverter is being
connected to or disconnected from the 12V power source.
IMPORTANT: Failure to make the correct connections will result in blown fuses
and permanent damage to the inverter.
5. 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 AC outlet.
4. Press and hold the ON/OFF switch to turn the inverter on. (The internal
speaker will make a brief "beep". This is normal.) The Watts LED will glow and
the digital display will show .
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.
IMPORTANT: 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.
