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.

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.
