Apple Setting Up Your Power Macintosh G4 (PCI & AGP) - Manual (Page 12)

12 Chapter 1
Plugging In the Computer
Before you plug your Macintosh into a wall socket, carefully read all the setup instructions in
this chapter. Then, before you connect any other equipment, follow the instructions in this
section to plug it in. When you are ready to begin, follow these steps:
1 Make sure the voltage switch on the back of the computer is set for the kind of voltage
system to which you will be connecting.
The voltage switch must be set correctly to avoid damaging your computer. An adhesive label
showing how to set the voltage may partly cover the voltage switch and power socket.
Remove the label. Look at the table “Voltage Switch Settings for Different Locations,” next.
Set the switch to show “115” for AC voltages in
the 100–120 V range. Set the switch to show
“230” for AC voltages in the 200–240 V range.
Check to see that the voltage switch on the back
of your computer is properly set before you plug
it in. If you need to change the setting, insert a
small screwdriver in this slot and slide the switch.
