Warning: Do not use an AC adapter’s polarized plug with an extension cord, receptacle, or other outlet unless the blades can be fully inserted to prevent blade exposure.

Cautions:

•You must use an AC adapter that supplies 9 volts and delivers at least 300 milliamps. Its center tip must be set to negative, and its plug must correctly fit the scanner’s PWR/DC 9V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

•When you finish using the AC adapter, disconnect it from the AC outlet first. Then disconnect it from the scanner.

Using Vehicle Battery Power

To power the scanner from your vehicle’s cigarette lighter socket, you need a DC Adapter, such as Cat. No. 270- 1560.

Cautions:

•You must use a DC adapter that supplies (regulated) 9-volt power and delivers at least 300 milliamps. Its center tip must be set to negative, and its plug must correctly fit the scanner’s PWR/DC 9V jack. The rec- ommended adapter meets these specifications. Using an adapter that does not meet these specifica- tions could damage the scanner or the adapter.

•To protect your vehicle’s electrical system, always plug the adapter into the scanner before you plug it into your vehicle’s cigarette-lighter socket. Always unplug the adapter from the vehicle’s cigarette- lighter socket before you unplug it from the scanner.
