User`s guide

Read the “Important Safety Instructions” at the beginning of
this manual for more information about choosing a suitable
environment for your system.
Also read “Working Comfortably” in Chapter 3 for guidelines
on creating a comfortable and safe working environment.
Setting the Voltage Selector- Switch
Your system is powered by a 200 watt power supply. The
power supply input voltage is controlled by a switch on the
computer’s back panel that may be set to 110 VAC or 220 VAC.
(The switch on your computer may read 115 VAC or 230 VAC;
these settings are equivalent to 110 VAC and 220 VAC.)
The computer is shipped with the voltage selector switch set to
110 VAC, which is appropriate for line source voltages between
100 and 120 VAC. This is generally the correct setting if you use
the computer in North America, South America, or Japan.
If you plan to operate the computer in the United Kingdom,
Europe, or some South American countries, you will almost
certainly need to reset the voltage selector switch to 220 VAC.
Line source voltages between 200 and 240 VAC are acceptable
with the switch set to 220 VAC.
Caution
Before you turn on the power to your system, make sure the
voltage selector switch is set appropriately for the electrical
power source in your location or you will seriously damage
your system.
