Using Your Computer Comfortably and Safely
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 36 for information on a more appropriate
model for demanding applications.
Do not crush, drop, or physically punish the removable hard disk
drive when it is outside of your computer.
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. 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
heat is a function of the level of system activity and battery
charge level.
ThinkPad Do's:
Store your removable hard disk drive in the appropriate container
or packaging when not in use.
