To power the scanner using an AC adaptor, connect the plug into the scan-
ner's PWR DC 9V jack. Then connect the AC adaptor to a standard AC out-
let.
WARNING: To prevent electric shock, do not use the AC adaptor's polarized
plug with an extension cord, receptacle, or other outlet unless you can fully
insert the blades to prevent blade exposure.
Note: Plug the adaptor into an easily accessible power outlet located near
the equipment.
Using Vehicle Battery Power
You can power the scanner from a vehicle's 12V power source (such as
cigarette-lighter socket) using a 9VDC at least 400-mA adaptor with 4.75mm
outer/1.7mm inner plug. Its center tip must be set to positive and its plug
must fit the scanner's PWR DC 9V jack. Using an adaptor that does not
meet these specifications could damage the scanner or the adaptor.
WARNING: Always connect the DC adaptor to the scanner before you con-
nect it to the power source. When you finish, disconnect the adaptor from
the power source before you disconnect it from the scanner.
To power the scanner using a DC adaptor, connect the plug into the scan-
ner's PWR DC 9V jack. Plug the other end of the DC adaptor into your ve-
hicle's cigarette-lighter socket.
NOTE: If you use a cigarette-lighter power cable and your vehicle's engine
is running, you might hear electrical noise from the engine while scanning.
This is normal.
