• When you disconnect a cable, pull on its connector or on its strain-
relief loop, not on the cable itself. As you pull out the connector, keep
it evenly aligned to avoid bending any connector pins. Also, before you
connect a cable make sure both connectors are correctly oriented and
aligned.
• Handle components with care. Hold a component such as a memory
module by its edges, not its pins.
• When preparing to remove a memory module from the system board
or disconnect a peripheral device from the computer, 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 your online User's Guide. If, after
following these procedures, you confirm that your computer is not
operating properly, contact Dell (see "Getting Help" in your 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:
• 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.
