•When unpacking a
•When transporting a sensitive component, first place it in an antistatic container or packaging.
•Handle all sensitive components in a
The following caution appears throughout this document to remind you of these precautions:
CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide.
When Using the Computer System
As you use the computer system, observe the following safety guidelines:
•Be sure the monitor and attached peripherals are electrically rated to operate with the alternating cur- rent (AC) power available in your location.
•To help prevent electric shock, plug the computer and peripheral power cables into properly grounded power sources. These cables are equipped with
•To help protect the computer system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or un- interruptible power supply.
•Be sure nothing rests on the computer system’s cables and that the cables are not located where they can be stepped on or tripped over.
•Do not spill food or liquids on the computer. If the computer gets wet, see Chapter 7, “Checking Inside the Computer.”
•Do not push any objects into the openings of the computer. Doing so can cause fire or electric shock by shorting out interior components.
•Keep the computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath the computer; do not place the computer in a
