NOTICE:

To avoid damaging your computer, set the manual voltage-selection

switch (on the back of the computer, if your computer has a voltage selection
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

even though the AC power available in Japan is 100 V.

NOTE:

Your computer’s power supply may or may not have a voltage selection

switch.

Your computer has 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.
