Handling Your Computer
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 40 for information on a more appropriate
model for demanding applications.
Do not crush or drop the external or removable hard disk,
diskette, or CD-ROM drive when it is outside your computer.
Do not press on the middle part of the diskette drive or CD-ROM
drive.
Do not insert a diskette at an angle. Not inserting the diskette
straight into the drive can damage the drive.
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.
Do not touch the surface of a compact disc; handle the compact
disc only by its edges.
Do not connect the modem to 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
heat is a function of the level of system activity and battery
charge level.
ThinkPad Do's
Store your CD-ROM drive in the CD carrying case and the
diskette drive in its enclosure.
