Handling your computer
Ÿ
Do not turn your computer over while the AC Adapter is plugged
in. This could break the adapter plug.
Ÿ
Do not use your computer when the temperature is below 10°C
or above 35°C (50°F to 95°F).
Ÿ
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.
Ÿ
Do not hard-mount your computer in a vehicle or anywhere that it
is subject to strong vibration. See “Ruggedized mobile
computers” on page 39 for information on a more appropriate
model for demanding applications.
Ÿ
Do not crush, drop, or physically punish the external or remov-
able hard disk when it is outside your computer.
Ÿ
Do not insert a diskette into the external disk drive at an angle.
Not inserting the diskette straight into the drive can damage the
head.
Ÿ
Do not place more than one label on a diskette. Multiple or loose
labels can detach or tear and then lodge in the drive.
Ÿ
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 tele-
phone cable in such places.
Ÿ
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 com-
puter is functioning or when the battery is charging. Your com-
puter dissipates some heat during normal operation. This heat is
a function of the level of the system activity and battery charge
level.
