Do not use or store your computer where the temperature is below 5° C or above 35° C (41° F and 95° F). Do not place your computer closer than 13 cm (5 in.) from any electrical appliance that generates a strong magnetic field, such as a motor, a magnet, a TV, a refrigerator, or large audio speakers. Do not hard-mount your computer in a vehicle or anywhere that it is subject to strong vibration. See "Ruggedized Mobile Computers" on page 60 for information on a more appropriate model for demanding applications.

Do not press on the middle part of the diskette drive. Do not insert a diskette at an angle. Not inserting the diskette straight into the drive can damage the drive. Do not insert a battery pack into the computer too hard. Do not place more than one label on a diskette. Multiple or loose labels can detach or tear and then lodge in the drive. Do not touch the lens on the CD-ROM tray. You should hold the compact disc by the edges and not touch its surface. Do not connect a PBX (private branch exchange) or other digital telephone extension line. Your computer can use only a public-switched telephone network (PSTN). Use of a phone line other than PSTN can damage your modem. If you are not sure which kind of phone line you are using, contact your telephone company. Many hotels or office buildings use digital telephone extension lines, so check before connecting the telephone cable in such places. Do not leave the base of your computer in contact with your lap or any part of your body for an extended period when the computer is functioning or when the battery is charging. Your computer dissipates some heat during normal operation. This Appendix C. Notices 55
