2. Try altering the position of the inverter, antenna cables, and
television power cord. Add an extension cord from the inverter
to the TV so as to isolate its power cord and antenna cables
from the 12V power source.
3. Try coiling the television power cord and the input cables
running from the 12V power source to the inverter.
4. Affix one or several “Ferrite Data Line Filters” to the television
power cord. Ferrite Data Line Filters can be purchased at
most electronic supply stores.
NOTE: You may hear a “buzzing” sound being emitted from
inexpensive sound systems when operated with the inverter. This
is due to ineffective filters in the sound system’s power supply.
Unfortunately, this problem can only be resolved by purchasing a
sound system with a higher quality power supply or higher quality filter.
Using the USB Port:
1. Plug the device into the USB port.
2. Turn the USB device on.
3. Reverse these steps when finished using the USB port.
The inverter draws power, even when the switch is
OFF. To avoid battery drain, disconnect the inverter when not in use.
6. POWER SOURCE
To get the best performance out of your inverter, we recommend that
you use it with the vehicle’s engine running.
Your average automobile or marine battery at full charge will provide
an ample power supply to the inverter for approximately 3 hours when
the engine is off. The actual length of time the inverter will function
depends on the age and condition of the battery and the power
demand being placed by the device being operated with the inverter.
If you decide to use the inverter while the engine is off, we
recommend you turn OFF the device plugged into the inverter
before starting the engine. To maintain battery power, start the
engine every 2 to 3 hours and let it run for approximately 10
minutes to recharge the battery.
Although it is not necessary to disconnect the inverter when turning
over the engine, it may briefly cease to operate as the battery
voltage decreases. While the inverter draws very low amperage
when not in use, it should be unplugged to avoid battery drain.
