PREPARATION

Your scanner’s display is protected during shipment by a piece of blue film. Peel off this film before you use the scanner.

CONNECTING POWER

Note: If a power failure occurs or if the DC cigarette-lighter power cable or AC adapter is disconnected, the scanner’s memory backup circuit keeps information in memory for up to 3 days.

Using Standard AC Power

You can power your scanner from a standard AC outlet using the sup- plied AC adapter.

Warning: Do not use the AC adapt- er’s polarized plug with an extension cord receptacle unless the blades can be fully inserted to prevent blade exposure.

Cautions:

•The supplied AC adapter sup- plies 12 volts and delivers 500 milliamps. Its center tip is set to positive, and its plug properly fits the scanner’s DC 12V jack. Using an AC adapter that does not meet these specifications could damage the scanner or the adapter.

•Be sure you connect the AC adapter to the scanner before you connect it to a standard AC outlet. Then disconnect the adapter from the AC outlet before you disconnect it from the scanner.

•If you have difficulty inserting the AC adapter’s polarized plug, do not force it. Turn it over and rein- sert it.

1.Insert the supplied AC adapter’s barrel plug into the scanner’s DC 12V jack.
