solving lack of output power in the TROUBLESHOOTING section of this manual. The
alarm will sound or if there is an excessive voltage drop between the battery and the
inverter.
NOTE: It is normal for the alarm to sound while the unit is being connected to, or
disconnected from, the power source. This is not indicative of a problem.
7. COMMON PROBLEMS
“Buzzing” sound in audio systems:
Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from their
speakers when operated from the Vector Power 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
that incorporates a higher quality power amplified supply.
Television Interference:
The Vector Power Inverter is shielded to minimize interference with TV signals. However,
in some instances, some interference may still be visible, particularly with weak TV signals.
Try the following corrective measures:
• Position the inverter as far as possible from the television, the antenna and the antenna
cables. Use an extension cable, if necessary
• Adjust the orientation of the inverter, the antenna cables and the TV power cord to minimize
interference
• Make sure that the antenna feeding the television provides an adequate (“snow free”) signal
and that high quality, shielded antenna cable is used
