PREPARATION

CONNECTING POWER

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. The scanner’s dis- play dims if the AC adapter you use does not provide the required 12 volts DC.

•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.

2.Plug the adapter’s power mod- ule into a standard AC outlet.

Memory Backup

If a power failure occurs or if the pow- er cord is disconnected, the scan- ner’s memory backup circuit keeps information in memory for up to 3 days.

Note: The memory backup circuit begins to protect the contents in memory within a few minutes after you plug in the scanner.
