Operating Instructions - Schumacher Electric XI75B Guide D'utilisation

6. OPERATING INSTRUCTIONS

1. Connect the converter (see Connecting Converter Cables section).
2. Make sure the device to be operated is turned OFF.
3. Plug the device into the converter's AC outlet.
4. Switch the converter's ON/OFF switch to the ON position.
5. Turn the device on.
6. To disconnect, reverse the above procedure.
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.
USING THE USB PORT
The USB port provides up to 2A at 5V DC.
1. Plug the device into the USB port.
2. Turn the USB device on (if necessary).
3. Reverse these steps when finished using the USB port.
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.
WARNING: The converter draws power, even when the switch is OFF. To avoid
battery drain, disconnect the converter when not in use.
