Battery Operating Time
Operating time will vary depending on the charge level of the
battery, its capacity and the power level drawn by the particular
AC load.
When using a vehicle battery as a power source, it is strongly
recommended to start the vehicle every one hour or two to
recharge the battery before its capacity drops too low. The
inverter can operate while the engine is running, but the normal
voltage dropping during starting of the engine may trigger the
inverter’s low voltage shutdown feature.
Interference with Electronic Equipment
Generally, most AC products operate with the inverter just as they
would with household AC power. Below is the information
concerning two possible exceptions.

Buzzing in audio systems and radios
Some stereo systems and AM-FM radios have inadequate
internal power supply filtering and “buzz” slightly when powered
by the inverter. Generally, the only solution is an audio product
with a higher quality filter.
Television interference
The inverter is shielded to minimize its interference with TV
signals. However, with weak TV signals interference may be
visible in the form of lines scrolling across the screen. The
following should minimize or eliminate the problem:
• Increase the distance between the inverter and the TV, antenna
and cables.
• Adjust the orientation of the inverter television, antenna and
cables.
• Maximize TV signal strength by using a better antenna and use
shielded antenna cable where possible.
