www.dell.com | support.dell.com CAUTION: Safety Instructions (continued) • 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. • Do not spill food or liquids on your computer. If the computer gets wet, consult your User's Guide. • Do not use your computer during an electrical storm unless the AC adapter cable has been disconnected from the electrical outlet. • When you use the AC adapter to run the computer, place the AC adapter in a ventilated area, such as a desk top or on the floor. • The AC adapter may become hot during normal operation of your computer. Use care when handling the adapter during or immediately after operation. 8 Setup and Quick Reference Guide
