As you use your computer, observe the following safe-handling guidelines.

When Using Your Computer

CAUTION: Do not operate your computer with any cover(s) (including the computer cover, filler brackets, front-panel inserts, and so on) removed or opened.

•To help avoid damaging your computer, be sure that the voltage selection switch is set to match the AC power available at your location:

–115 V/60 Hz in most of North and South America and some Far Eastern countries such as South Korea and Taiwan

–100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan

–230 V/50 Hz in most of Europe, the Middle East, and the Far East

Also be sure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.

•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 avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting or connecting a non-USB device from the computer.
