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. Use
true
RMS reading meter.
Inverter is overloaded. Reduce load to 50 watts max. to maintain regulation.
Input voltage below 10.5 volts. Keep input voltage above 10.5 volts to maintain regulation.
