Carrying the Computer
When you carry the computer, follow these instructions.
1 Remove any diskette from the drive.
2 Turn off all attached options.
3 Unplug all external cables and cords connected to the computer.
4 Firmly close the display. It is recommended that the display be
closed whenever the computer is moved in order to prevent any
damage to data on the fixed disk.
You can now carry the computer. Using the carrying case and
carrying the Reference Summary and the backup copy of the
Reference Diskette are recommended.
Caring for Your Computer
For maximum computer efficiency, follow these instructions.
•To prevent damaging the LCD:
- Avoid scratching to its surface
- Avoid placing anything heavy on the LCD when closed
- Avoid twisting or hitting to the LCD
•Keep your computer away from devices that generate a strong
magnetic field such as a motor, refrigerator, or speaker.
•Your computer is designed to operate in temperatures between 5°
C and 35°C(41°F and 95°F). However, if you plan to use the
diskette drive, you should be aware that diskettes cannot be used
below 10°C(50°F). If the temperature is outside this range, the
temperature icon appears on the system status display; the
computer automatically enters Suspend Mode.
•Keep your computer in a place where the humidity is between 5%
and 95°/a (non-condensing). If the humidity is outside this

range, the dew point (humidity) icon appears on the system status
display panel.
•If you do not use your computer for a long period, remove the re-
chargeable battery from the center compartment and keep it in a
cool place.
