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.
SAFETY: 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.
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.
