Common Power Output Problems

Possible Causes    

Recommendations

Battery voltage     

Recharge battery or check

below 10.7 volts 

DC power supply.

Equipment being operated     

Reduce load to maximum 100 watts.

draws too much power

Inverter in thermal    

Allow inverter to cool down. Ensure 

shutdown condition

there is adequate ventilation around
the unit, and the load is no more
than 100 watts for continuous operation.

AC output is shorted    

Disconnect the AC appliance. Press the
inverter ON/OFF Power pushbutton to
turn the unit OFF. Wait a few seconds,
then press the pushbutton again to turn it
back ON.

CARE AND MAINTENANCE

Storage

1. Ideal storage temperature range is 0-40°C (32-104°F).
2. Store and use the 

100 Watt Slim Power Inverter

in a cool, dry place with

adequate ventilation for all-around air circulation.

3. Avoid locations that are exposed to heating units, radiators, direct sunlight, or

excessive humidity or dampness.

Fuse Replacement (12 Volt DC Accessory Cord)

1. Unscrew the cap of the barrel end of the 12 Volt DC Cord (turning counter-

clockwise) and lift off.

2. Pull the fuse straight out.
3. Replace with a new 10 amp fuse.
4. Screw the cap back onto the plug (turning clockwise).

TROUBLESHOOTING

Common Audio/Visual Problems

Problem: Buzzing Sound in Audio Systems
Some inexpensive stereo systems and boom boxes make a buzzing sound when
operated from the inverter, because the power supply in the electronic device does
not properly filter the modified sine wave produced by the inverter. The only solution
to this problem is to use a sound system that has a higher quality power supply.
Problem: Television Interference
The 

100 Watt Slim Power Inverter

is shielded to minimize interference with TV

signals. However, in some instances, some interference may still be visible, especially
when the TV signal is weak. Try the following to improve the picture:
1.  Move the 100 Watt Inverter as far away as possible from the TV set, the antenna,

and the antenna cables. Use a short AC extension cord, if necessary. 

2.  Adjust the orientation of the antenna cables, and the TV power cord to minimize

interference.

3.  Make sure that the antenna feeding the TV provides an adequate (snow-free)

signal and that high quality, shielded antenna cable is used.

Fault LED Lights/Alert Buzzer Sounds

When the Power/Fault LED turns from blue (indicating the unit is powered) to red and
the alert buzzer sounds, a fault condition is present and the unit will automatically shut
down shortly. See “Protective Features” on page 5 and “Common Power Output
Problems” below.
