using AC power

You can power the scanner using a 6V, 300 mA AC adapter and a size B Adaptaplug™ adapter (neither supplied). Both are available at your local RadioShack store.

Cautions:

•You must use a Class 2 power source that supplies 6V DC and delivers at least 300 mA. Its center tip must be set to positive and its plug must fit the scanner's DC 6V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

•Always connect the AC adapter to the scanner before you connect it to AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the scanner.

Follow these steps to use the scanner on AC power. Make sure the power is turned off.

Insert the Adaptaplug into the AC adapter's cord so it reads TIP +. Then, insert the Adaptaplug into the scanner's DC 6V jack.

Plug the AC adapter into a standard AC outlet.
