• 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.
• Do not push any objects into the openings of your computer. Doing so can cause fire or
electric shock by shorting out interior components.
• Keep your computer away from radiators and heat sources. Also, do not block cooling
vents. Avoid placing loose papers underneath your computer; do not place your computer
in a closed-in wall unit or on a bed, sofa, or rug.
• Do not spill food or liquids on your computer. If the computer gets wet, consult your
User’s Guide.
CAUTION: Safety Instructions (continued)
When Using Your Computer
As you use your computer, observe the following safe-handling guidelines.
CAUTION: Do not operate your computer with any cover(s) (including computer
covers, bezels, filler brackets, front-panel inserts, and so on) removed.
• Your computer is equipped with one of the following:
– A fixed-voltage power supply — Computers with a fixed-voltage power supply do not
have a voltage selection switch on the back panel and operate at only one voltage
(see the regulatory label on the outside of the computer for its operating voltage).
– An auto-sensing voltage circuit — Computers with an auto-sensing voltage circuit do
not have a voltage selection switch on the back panel and automatically detect the
correct operating voltage.
– A manual voltage selection switch — Computers with a voltage selection switch on
the back panel must be manually set to operate at the correct operating voltage.
NOTICE:
To help avoid damaging a computer with a manual voltage selection switch, set the
switch for the voltage that most closely matches the AC power available in your location. For Japan,
the voltage selection switch must be set to the 115-V position even though the AC power available in
Japan is 100 V. Also, ensure that your monitor and attached devices are electrically rated to
operate with the AC power available in your location.
