Compaq Armada 7400 Reference Manual page 128

The computer is designed to run demanding applications that
require PC Cards, CD-ROM drives, and large amounts of RAM
while maintaining full processor performance.
As a result of increased power consumption, it is normal for the
computer to feel warm to hot when being used for extended
periods.
The computer complies with international safety standards for
temperatures of user-accessible surfaces.
For safety and convenience when traveling, follow these
guidelines:
1. Back up your data. Do not expose your backups to electrical or
magnetic impulses while stored or in transit.
2. If there is a diskette or compact disc in a drive, remove it.
3. Turn off the computer and external devices.
4. Close the computer.
5. Disconnect external equipment from the computer.
6. Close the connector cover and all exterior doors.
7. Hand-carry the computer in a briefcase or other protective
case. Do not check the computer with your luggage.
Check with the airline if you plan to use the computer on the
plane. In-flight computer use is at the discretion of the airline.
There are three types of airport security devices:
X-ray machines (the conveyor belt device you set your bags on),
magnetic detectors (the device you walk through), and security
magnetic wands (the hand-held device used by security
personnel). You can send your computer and diskettes through
airport X-ray machines. However, Compaq recommends that you
do not send your computer and diskettes through airport magnetic
detectors or expose them to security magnetic wands.
