Cautions:

•The DC cigarette-lighter power cable must be capable of deliv- ering 12 volts and 500 milli- amps, its center tip must be set to positive, and its barrel plug must correctly fit the scanner's DC 12V jack. The recommended power cable meets these speci- fications. Using a power cable that does not meet these specifi- cations could damage the scan- ner or the power cable.

•Always plug the power cable into the scanner before you plug it into your vehicle's cigarette- lighter socket. Always unplug the power cable from the vehi- cle's cigarette-lighter socket before you unplug it from the scanner.

Follow these steps to use vehicle battery power.

Note: If the scanner does not oper- ate properly when you use a ciga- rette-lighter power cable, unplug the power cable from the cigarette- lighter socket and clean the socket to remove ashes and other debris.
