Use the following safety guidelines to protect yourself and your computer.

When Using Your Computer

CAUTION: Do not operate your computer with any cover(s)

(including the computer cover, filler brackets, front-panel inserts, and so on) removed or opened.

• Your computer is equipped with either an auto-sensing voltage selector

or a manual voltage-selection switch. Computers with an auto-sensing voltage selector do not have a voltage-selection switch on the back panel and automatically detect the correct operating voltage. Computers with a voltage-selection switch on the back panel must be manually set to operate at the correct operating voltage. To help avoid damaging a computer with a manual voltage-selection switch, be sure that the voltage-selection switch is set to match the AC power available at your location:

– 115 V/60 Hz in most of North and South America and some Far

Eastern countries such as South Korea and Taiwan

– 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan

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

Also be sure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.

• To avoid shorting out your computer when disconnecting a network

cable, first unplug the cable from the network adapter on the back of your computer, and then from the network jack. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then into the network adapter.

www.dell.com | support.dell.com

• To help avoid possible damage to the system board, wait 5 seconds

after turning off the computer before disconnecting or connecting a non-USB device from the computer.

• To help prevent electric shock, plug the computer and device power

cables into properly grounded power sources. These cables are equipped with 3-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 3-wire cable with properly grounded plugs.

• To help protect your computer from sudden, transient increases and

decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply.

• Be sure that nothing rests on your computer’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, contact Dell (see page 84).

• 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; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug.

Ergonomic Computing Habits

CAUTION: Improper or prolonged keyboard use may result in

injury.

CAUTION: Viewing the 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 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.

When Working Inside Your Computer

Before you open the computer cover, perform the following steps in the sequence indicated.

CAUTION: Do not attempt to service the computer yourself,

except as explained in this guide and elsewhere in Dell documentation. Always follow installation and service instructions closely.

Turn off the computer (see page 22).

2 Turn off all devices.

3 Ground yourself by touching an unpainted metal surface at the back of

the computer before touching anything inside your computer.

While you work, periodically touch an unpainted metal surface on the computer to dissipate any static electricity that might harm internal components.

4 Disconnect any devices connected to the computer, including the

monitor, from their electrical outlets to reduce the potential for personal injury or shock. Also, disconnect any telephone or telecommunication lines from the computer.

5 Disconnect the power cable to your computer, and then press the

power button to ground the system board.

In addition, take note of these safety guidelines when appropriate:

• When you disconnect a cable, pull on its connector, not on the cable

itself. As you pull connectors apart, keep them evenly aligned to avoid bending any pins. Also, before you connect a cable, make sure that both connectors are correctly oriented and aligned.

• Handle components and cards with care. Don’t touch the components

on a card. Hold a card by its edges or by its metal bracket.

CAUTION: There is a danger of a new battery exploding if it is

incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer’s instructions.

Protecting Against Electrostatic Discharge

To prevent static damage, discharge static electricity from your body before you touch anything inside your computer and periodically while you work inside the computer. You can do so by touching an unpainted metal surface on the back of the computer.

You can also take the following steps to prevent static damage:

• Do not remove items from their antistatic packing material until you

are ready to install them in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

• When transporting a sensitive component, first place it in an antistatic

container or packaging.
