EXT. PWR Jack

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

Caution: Use only the supplied AC adapter/charger. It is specifically designed for this scanner.

Using Vehicle Battery Power

To power the scanner from your vehicle's cigarette-light- er socket, you need a DC cigarette-lighter power cable, such as Cat. No. 270-031.

Cautions:

The DC cigarette-lighter power cable must be capa- ble of delivering 12 volts, its center tip must be set to positive, and its barrel plug must correctly fit the scanner's EXT. PWR jack. The recommended power cable meets these specifications. Using a power cable that does not meet these specifications could damage the scanner or the power cable.

To protect your vehicle's electrical system, 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 vehicle's cigarette-lighter socket before you unplug it from the scanner.

Insert the DC cigarette-lighter power cable's barrel plug into the EXT. PWR jack, then plug the power cable's other end into your vehicle's cigarette-lighter

socket. .
