| Caution:
Be sure AC power cord meets the relevant local safety standards.
Place the scanner close enough to the computer for the interface cable to reach it easily. Do not place or store the scanner or the AC adapter outdoors, near excessive dirt or dust, water, heat sources, or in locations subject to shocks, vibrations, high temperature or humidity, direct sunlight, strong light sources, or rapid changes in temperature or humidity. Do not use with wet hands. Place the scanner and the AC adapter near an electrical outlet where the power cord can be easily unplugged. Place the power cord to avoid abrasions, cuts, fraying, crimping, and kinking. Do not place objects on top of the power cord and do not allow the AC adapter or the power cord to be stepped on or run over. Be particularly careful to keep the power cord straight at the ends and the points where they enter and leave the AC adapter. Use only the AC adapter model A221B/E that comes with your scanner. Using any other adapter could cause fire, electrical shock, or injury. The AC adapter is designed for use with the scanner with which it was included. Do not attempt to use it with other electronic devices unless specified. Use only the type of power source indicated on the AC adapter's label, and always supply power directly from a standard domestic electrical outlet with the AC power cord that meets the relevant local safety standards. Avoid using outlets on the same circuit as photocopiers or air control systems that regularly switch on and off. If you use an extension cord with the scanner, make sure the total ampere rating of the devices plugged into the extension cord does not exceed the cord's ampere rating. Also, make sure the total ampere rating of all devices plugged into the electrical outlet does not exceed the electrical outlet's ampere rating. Do not place multiple loads on the electrical outlet. When connecting this product to a computer or another device with a cable, make sure the orientations of the connectors are correct. Each connector has only one correct orientation. Inserting a connector with the wrong orientation may damage both devices connected by the cable. Do not remove the memory card or turn off this product while the computer and the memory card are communicating (when the memory card light is flashing). The methods for using memory cards vary according to card type. Be sure to refer to the documentation packaged with your memory card for details. Use only memory cards compatible with this product. Never disassemble, modify, or attempt to repair the AC adapter, power cord, scanner, and option by yourself except as specifically explained in the scanner's guides. Do not insert objects into any openings as they may touch dangerous voltage points or short out parts. Beware of electrical shock hazards. Unplug the scanner and the AC adapter, and refer servicing to qualified service personnel under the following conditions: The power cord or plug is damaged; liquid has entered the scanner or the AC adapter; the scanner or the AC adapter has been dropped or the case damaged; the scanner or the AC adapter does not operate normally or exhibits a distinct change in performance. (Do not adjust controls that are not covered by the operating instructions.) Unplug the scanner and the AC adapter before cleaning. Clean with a damp cloth only. Do not use liquid or aerosol cleaners. If you are not going to use the scanner for a long period, be sure to unplug the AC adapter from the electrical outlet. ## Warnings, Cautions, and Notes
