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 Power Station 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 Power Station 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.
Common Power Output Problems
Possible Causes
Recommendations
Battery voltage
Recharge battery or check
below 10.6 volts.
DC power supply.
Equipment being operated
draws too much power.
Reduce load to maximum 100 watts.
Inverter in thermal
shutdown condition
Allow inverter to cool down. Shutdown inverter
and ensure that there is adequate ventilation
around unit, and load is no more than 100 watts
for continuous operation.
Main fuse failed (blown). Replace fuse in DC connector.
Inverter is overloaded.
Reduce load to 100 watts max. to maintain
regulation.
Fuse Replacement
Replace the fuse inside of the DC charger plug with a fuse of the same type and
rating.

Protective Features
The power station monitors the following conditions:
Low Battery Voltage:
This condition is not harmful to the power station but could
damage the power source, so the power station automatically shuts down when
input voltage drops to 10.6 volts. When this condition is corrected, the unit will
auto-reset.
Short Circuit Protection:
The power station will automatically shut down when
short circuit occurs. The power station will auto-reset after removing the short circuit.
