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 FCCcompliant 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. · · · DELL CONFIDENTIAL ­ PRELIMINARY 9/26/02 9 FILE LOCATION: S:\SYSTEMS\Meteor\UG\A04\safeinfo.fm w w w. d e l l . c o m | s u p p o r t . d e l l . c o m 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 "Repairing a Wet Computer." 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 or to charge the battery, 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. · · · · · · · · DELL CONFIDENTIAL ­ PRELIMINARY 9/26/02 10 FILE LOCATION: S:\SYSTEMS\Meteor\UG\A04\safeinfo.fm When Using Your Computer As you use your computer, observe the following safe-handling guidelines. CAUTION: Do not operate your computer with any cover(s) (including computer covers, bezels, filler brackets, front-panel inserts, and so on) removed. · Your computer is equipped with one of the following: ­ A fixed-voltage power supply -- Computers with a fixed-voltage power supply do not have a voltage selection switch on the back panel and operate at only one voltage (see the regulatory label on the outside of the computer for its operating voltage). An auto-sensing voltage circuit -- Computers with an auto-sensing voltage circuit do not have a voltage selection switch on the back panel and automatically detect the correct operating voltage. A manual voltage selection switch -- Computers with a voltage selection switch on the back panel must be manually set to operate at the correct operating voltage. ­ ­ NOTICE: To help avoid damaging a computer with a manual voltage selection switch, set the switch for the voltage that most closely matches the AC power available in your location. For Japan, the voltage selection switch must be set to the 115-V position even though the AC power available in Japan is 100 V. Also, ensure that your monitor and attached devices are electrically rated to operate with the AC power available in your location. · Before working inside the computer, unplug the computer to help prevent electric shock or system board damage. Certain system board components continue to receive power any time the computer is connected to AC power.
