Ergonomic Computing Habits - Dell Latitude X200 Systeminformationshandbuch

• When preparing to remove a memory module from the system board,
turn off the computer, disconnect the AC adapter cable, and then wait
5 seconds before proceeding to help avoid possible damage to the
system board.
• Clean the display with a soft, clean cloth and commercial window
cleaner that does not contain wax or abrasives. Apply the cleaner to the
cloth; then stroke the cloth across the display in one direction, moving
from the top of the display to the bottom. If the display contains
grease or some other contaminant, use isopropyl alcohol instead of
commercial window cleaner.
• If your computer gets wet or is damaged, follow the procedures
described in "Solving Problems" in the User's Guide. If, after following
these procedures, you confirm that your computer is not operating
properly, contact Dell. (See "Getting Help" in the User's Guide for the
appropriate telephone number.)

Ergonomic Computing Habits

CAUTION: Improper or prolonged keyboard use may result in
injury.
CAUTION: Viewing the display or external monitor screen for
extended periods of time may result in eye strain.
For comfort and efficiency, observe the following ergonomic guidelines
when setting up and using your computer:
• This is a portable computer and is not designed for continuous
operation as office equipment. For extended use in an office, an
external monitor and an external keyboard are recommended.
• Position your computer directly in front of you as you work.
• Adjust the tilt of the computer's display, its contrast and/or brightness
settings, and the lighting around you (such as overhead lights, desk
lamps, and the curtains or blinds on nearby windows) to minimize
reflections and glare on the display.
• When using an external monitor with your computer, set the monitor
at a comfortable viewing distance (usually 510 to 610 millimeters [20
to 24 inches] from your eyes). Make sure the monitor screen is at eye
level or slightly lower when you are sitting in front of the monitor.
• Use a chair that provides good lower-back support.
