switch
Your computer is equipped with a manual voltage selection
switch. 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.
NOTICE: In Japan, the voltage selection switch must be
set to the 115-V position.
Also, ensure that your monitor and attached devices are
electrically rated to operate with the AC power available in
your location.

NOTE: The integrated parallel connector is automatically
disabled if the computer detects an installed card containing a
parallel connector configured to the same address. For more
information, see "System Setup Options" in the User’s Guide.
