Icon Description
Plug powered speakers, an external amplifier, or headphones
into this jack.
Before turning on your computer, make sure that this switch is
in the correct position for the correct power available. The
switch is preset at the factory with the correct voltage for your
area.
In the United States, the utility power is supplied at a nominal
115 volts at 60 Hz. The power supply should always be set to
this when your computer is operating in the United States. In
other areas of the world, such as Europe, the utility power is
supplied at 230 volts at 50 Hz. If your computer is operating
in an environment such as this, the voltage switch should be
moved to 230.
