CAUTION: Safety Instructions 9

CAUTION: Safety Instructions

Use the following safety guidelines to help ensure your own personal safety and to help protect

your computer and working environment from potential damage.

General

• Do not attempt to service the computer yourself unless you are a trained service

technician. Always follow installation instructions closely.

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

grounded electrical outlets. 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 avoid the potential hazard of electric shock, do not use your computer during an

electrical storm.

• To help avoid the potential hazard of electric shock, do not connect or disconnect any

cables or perform maintenance or reconfiguration of this product during an electrical

storm.

• If your computer includes a modem, the cable used with the modem should be

manufactured with a minimum wire size of 26 American wire gauge (AWG) and an FCC-

compliant RJ-11 modular plug.

• Before you clean your computer, disconnect the computer from the electrical outlet.

Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol

cleaners, which may contain flammable substances.

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

computer before disconnecting a device from the computer.

10 CAUTION: Safety Instructions

www.dell.com | support.dell.com

• 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.

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

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

(UPS).

• Ensure 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 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.
