Using Standard AC Power

You can power the scanner from a standard AC outlet using an option- al 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 unless 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 ALKALINE JACK NI-CDis set to the correct position (see “Using Internal Batteries” on Page 8).

1.Turn VOLUME counterclockwise until it clicks to make sure power is turned off.

2.Plug the adapter’s 3.4 mm outside diameter/1.3 mm inside diame- ter barrel plug into your scanner’s POWER jack.

3. Plug the other end of the adapter into a standard AC outlet.
