6. Turn the converter on. The Power Out LED will glow and the digital display
will show O.
7. Turn the device on. The display will now show the total wattage used by the
device. To change the digital display, press the ON/OFF switch.
8. To disconnect, reverse the above procedure.
9. Press and hold the ON/OFF switch to turn the converter off.
NOTE: If more than one device is to be powered, start one device at a time to
avoid a power surge and overloading the converter. The surge load of each device
should not exceed the converter's Continuous Operation wattage rate.
ATTENTION: If there is a short circuit or power surge in the device,  will display
and the alarm will sound. Press the ON/OFF switch to turn off the alarm. If the 
displays after several attempts, there is a short circuit or the device requires more
"starting" or "peak" load than the converter is capable of providing.
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. 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 12 volt power source.
2. Try coiling the television power cord and the input cables running from the
12 volt power source to the converter.
3. 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.
4. Try grounding the converter with an 18 AWG (minimum) wire, using as
short a length as possible.
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 (Model PID-500-USB)
The USB port provides up to 2A 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.
WARNING: The converter draws power, even when the switch is OFF.
To avoid battery drain, disconnect the converter when not in use.
