Voltage selection		Before turning on your computer, make sure that this switch is in the correct
switch		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. For more
		information, see “Checking the voltage selection” on page 18.
