Important: At the end of a rechargeable battery’s use- ful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be available are: municipal curb-side collection, drop-off boxes at retailers such as your local Ra- dioShack store, recycling collection centers, and mail- back programs.

Using AC Power

You can power the scanner from a standard AC outlet using an optional AC adapter (such as Cat. No. 273- 1665).

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

Cautions:

•The recommended AC adapter supplies 9 volts and delivers at least 300 milliamps. It has a barrel plug with a center negative tip that correctly fits the scanner’s POWER jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

•To protect your scanner and AC adapter, always plug the adapter into the scanner before you plug it into the AC outlet, and always unplug the adapter from the AC outlet before you unplug it from the scanner.

•If batteries are installed, make sure the battery switch inside the battery compartment is set to the correct position (see “Using Internal Batteries” on Page 9).
