User's Manual

If you purchased any optional equipment that goes inside the
computer-such as option cards, memory modules, a hard disk
drive, or a diskette drive-you should install these devices
before you connect your computer. See Chapters 3 and 4 for
instructions.
Setting the Voltage Selector Switch
Your system is powered by a 200 Watt power supply. The
power supply voltage is controlled by a voltage selector switch
on the computer’s back panel. You can set this switch to
110 VAC or 220 VAC.
EPSON ships the computer with the voltage selector switch set
to 110 VAC. This setting is appropriate for line source voltages
between 100 and 120 VAC, and is generally the appropriate
setting to select if you plan to use your computer in North
America, Mexico, or Japan.
If you plan to operate the computer in the United Kingdom,
Europe, or South American countries, you will probably need
to reset the voltage selector switch to 220 VAC. Doing so allows
your computer to handle line source voltages between 200 and
240 VAC.
Caution
Before you turn on the power to your system, make sure the
voltage selector is set to the appropriate setting for the
electrical power source in your location or you will seriously
damage your system.
