Use the following safety guidelines to help protect your computer system from poten-

tial damage and to ensure your own personal safety.

As you use your computer system, observe the following safety guidelines.

To help avoid damaging your computer, be sure the voltage selection switch on

the power supply is set to match the alternating current (AC) power available at

your location:

— 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far

Eastern countries such as Japan, South Korea, and Taiwan

— 230 V/50 Hz in most of Europe, the Middle East, and the Far East

Also be sure your monitor and attached peripherals are electrically rated to oper-

ate with the AC power available in your location.

To help avoid possible damage to the system board, wait 5 seconds after turning

off the system before disconnecting a device from the computer.

To help prevent electric shock, plug the computer and peripheral power cables

into properly grounded power sources. These cables are equipped with three-

prong plugs to help ensure proper grounding. Do not use adapter plugs or

remove the grounding prong from a cable. If you must use an extension cable,

use a three-wire cable with properly grounded plugs.

To help protect your computer system from sudden, transient increases and

decreases in electrical power, use a surge suppressor, line conditioner, or un-

interruptible power supply (UPS).

Be sure nothing rests on your computer system’s cables and that the cables are

not located where they can be stepped on or tripped over.

Do not spill food or liquids on your computer. If the computer gets wet, call your

network administrator.

Do not push any objects into the openings of your computer. Doing so can cause

fire or electric shock by shorting out interior components.

Keep your computer away from radiators and heat sources. Also, do not block

cooling vents. Avoid placing loose papers underneath your computer, and do not

place your computer in a closed-in wall unit or on a bed, sofa, or rug.

When you disconnect a cable, pull on its connector or on its strain-relief loop, not

on the cable itself. Some cables have a connector with locking tabs; if you are dis-

connecting this type of cable, press in on the locking tabs before disconnecting

the cable. As you pull connectors apart, keep them evenly aligned to avoid bend-

ing any connector pins. Also, before you connect a cable, make sure both

connectors are correctly oriented and aligned.

For comfort and efficiency, observe the following ergonomic guidelines when setting

up and using your computer system:

Position your system so that the monitor and keyboard are directly in front of you

as you work. Special shelves are available (from Dell and other sources) to help

you correctly position your keyboard.

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.

Adjust the tilt of the monitor, its contrast and 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 monitor screen.

Use a chair that provides good lower back support.

Keep your forearms horizontal with your wrists in a neutral, comfortable position

while using the keyboard or mouse.

Always leave space to rest your hands while using the keyboard or mouse.

Let your upper arms hang naturally at your sides.

Sit erect, with your feet resting on the floor and your thighs level.

When sitting, make sure the weight of your legs is on your feet and not on the

front of your chair seat. Adjust your chair’s height or use a footrest, if necessary,

to maintain proper posture.

Vary your work activities. Try to organize your work so that you do not have to

type for extended periods of time. When you stop typing, try to do things that

use both hands.
