‡
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.
‡
Before you clean your computer, turn it off, unplug it from its power source, and
remove the battery pack(s).
‡
Clean your computer with a soft cloth dampened with water rather than with
liquid or aerosol cleaners.
‡
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
“Troubleshooting Your Computer” 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.)

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.
‡
When using an external monitor with your computer, set the monitor at a
comfortable viewing distance (usually 510 to 610 millimeters [mm] [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.
