Common Audio/Visual Problems
Problem: Buzzing Sound In Audio Systems
Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from their speakers when operated from the Power Force 50™ inverter, 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 sound system that has a higher quality power supply internally.
Problem: Television Interference
The Vector™ Power Force 50™ is shielded to minimize interference with TV signals. However, in some instances, some interference may still be visible, particularly when the TV signal is weak. Try the following corrective measures:
•Position the Pocket Generator™ as far as possible from the TV set, the antennae, and the antennae cables. Use an extension cable, if necessary.
•Adjust the orientation of the Pocket Generator™, the antennae cables, and the TV power cord to minimize interference.
•Make sure that the antennae feeding the TV provides an adequate (“snow free”) signal and that high quality, shielded antennae cable is used.
Common Power Output Problems
Problem: Lack Of Power Output
Possible Causes | Recommendations |
Inverter not adequately | Turn power inverter switch OFF and |
warmed up. | then ON again. Repeat if necessary. |
Battery voltage | Recharge or replace Pocket Generator™ battery. |
below 10 volts. |
|
Equipment being operated | Reduce load to maximum 50 watts. |
draws too much power. |
|
Inverter in thermal | Allow inverter to cool down. Ensure that there is |
shutdown condition. | adequate ventilation around unit, and load is no |
| more than 50 watts for continuous operation. |
Main fuse failed (blown). | Replace Pocket Generator™ fuse. |
Problem: Low Output Voltage
Using average reading voltmeter. Inverter is overloaded.
Input voltage below 10.5 volts.
Use true RMS reading meter.
Reduce load to 50 watts max. to maintain regulation. Keep input voltage above 10.5 volts to maintain regulation.
