NOTE: You can use an extension cord from the converter to the
device without significantly decreasing the power being generated
by the converter. For best operating results, the extension cord
should be no longer than 50 feet.
Using the converter to operate a TV or audio device:
The converter is shielded and filtered to minimize signal
interference. Despite this, some interference may occur with your
television picture, especially with weak signals. Below are some
suggestions to try and improve reception.
1. Make sure the television antenna produces a clear signal
under normal operating conditions (i.e. at home plugged into a
standard 120V AC wall outlet). Also, ensure that the antenna
cable is adequately shielded and of good quality.
2. Try altering the position of the converter, antenna cables,
and television power cord. Add an extension cord from the
converter to the TV, 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 converter.
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 converter.
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:
The USB Port provides up to 2.1A at 5V DC.
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 converter draws power, even when the
switch is OFF. To avoid battery drain, disconnect
the converter when not in use.
