OPERATING INSTRUCTIONS (MODEL PI-120)

1. Plug the included power cable into the inverter. Note the
plug will only fit into the outlet one way.
2. If connecting in a vehicle, remove the cigarette lighter
from its outlet.
3. Push the 12-volt power plug firmly into the outlet. Note: In
an airplane power outlet the plug will only fit into the outlet
one way.
4. The LED indicator light should glow BLUE verifying the
inverter is receiving power. If the LED indicator is not on,
read "LED INDICATOR AND SHUTDOWN PROTEC-
TION" section.
5. Make sure the device to be operated is turned OFF.
6. Plug the device into the inverter AC outlet or USB outlet.
7. Turn the device on.
8. To disconnect, reverse the above procedure.
NOTE: You may hear a "buzzing" sound being emitted from in-
expensive 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.

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 be-
ing operated with the inverter.
