Operating Instructions

1.Push the Power Inverter 140 firmly into the 12V accessory outlet. The LED indicator light should glow GREEN verifying the inverter is receiving power. (If connecting in a vehicle, remove the cigarette lighter from its outlet.)

2.Make sure that the device to be operated is turned OFF.

3.Plug the device into the Power Inverter 140 AC outlet.

4.Turn the device on. If the LED Indicator briefly blinks when you first plug the inverter in, it is a sign that there is a short circuit within the power supply. Remove the 12-volt plug from the 12-volt accessory outlet. Firmly reinsert the plug. If this does not remedy the problem, try using a different 12-volt accessory power outlet.

Note: A ‘’buzzing’’ sound emitted from inexpensive sound systems is the result of ineffective filters in the sound system. This can be resolved by purchasing a sound system with a higher quality power supply or higher quality filter.
