Dell 9N756, 4500 manual When Using Your Computer

Use the following safety guidelines to protect yourself and your computer.

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.

•Your computer is equipped with either an auto-sensing voltage selector or a manual voltage selection switch. Computers with an auto-sensing voltage selector do not have a voltage selection switch on the back panel and automatically detect the correct operating voltage. Computers with a voltage selection switch on the back panel must be manually set to operate at the correct operating voltage. To help avoid damaging a computer with a manual voltage selection switch, 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

NOTE: The voltage selection switch must be set to the 115V position even though the AC supply in Japan is 100 V.

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

NOTE: Auto-select power supplies do not require a voltage selection switch. Your power supply may not have this switch.

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.
