Operation of the USB Charging Port
1. Connect the inverter to a functioning 12 volt DC power source as described in this Instruction Manual. Make
sure there is adequate space for proper ventilation of the inverter.
2. Press the Power Pushbutton to turn the unit ON.
3. The Power/Fault LED Indicator will light green, indicating a proper connection. If the the Power/Fault LED lights
red, indicating a fault condition exists, refer to the “Troubleshooting” section of this Instruction Manual.
4. Plug the USB-powered device into the inverter’s USB Charging Port and operate normally.
Note:
This unit’s USB Charging Port does not support data communication. It only provides 5 volts/500mA DC power to an
external USB-powered device. Remember to disconnect the inverter from any power source when not in use.
TROUBLESHOOTING GUIDE
Common Audio/Visual Problems
PROBLEM
SOLUTION
“Buzzing” sound in
audio systems
Inexpensive stereo systems and “boom boxes” may emit a buzzing sound from their
speakers when operated from your inverter. This occurs because the power supply in
the electronic device does not adequately filter the modified sine wave produced by the
inverter. The only solution to this problem is to use a higher quality sound system.
Television
Interference
Your inverter is shielded to minimize interference with TV signals. However, in some
instances, some interference may still occur, particularly where TV signals are weak.
Try the following corrective measures:
• Place the inverter as far as possible from the television. Use an extension cable, if
necessary.
• Readjust the orientation of the inverter, the antenna cables and the TV power cord to
minimize interference.
• Make sure the antenna feeding the television provides an adequate (“snow free”)
signal and that high quality, shielded antenna cable is used.
• Do not use the inverter to operate high-power appliances or tools at the same time
you are using it to operate the TV.
• Make sure the inverter’s case is properly grounded (refer to the “Permanent
Installation Procedure” section of this Instruction Manual).
