Safety Instructions 9
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.
