Using Standard AC Power

The CHARGE jack supplies power to operate the scanner and also charges the internal batteries. Use the CHARGE jack only when you in- stall rechargeable nickel-cadmium batteries.

Warning: Never use the CHARGE jack with non-rechargeable batteries. If you try to recharge non-rechargeable batteries, they become very hot and could explode.

To power the scanner from AC power, you need an AC adapter such as Radio Shack Cat. No. 20-188. Plug the adapter’s barrel plug into the scanner’s DC 9V POWER jack. Then plug the adapter’s power module into a standard AC outlet.

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 DC 9V POWER jack. The rec- ommended adapter meets these specifications. Using an adapter that does not meet these specifications could seriously 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.

Note: If you installed rechargeable nickel-cadmium batteries in the scanner, remove the cap from the CHARGE jack and connect the AC adapter to it. This powers the scanner and recharges the batteries at the same time. See “Charging Nickel-Cadmium Batteries.”
