Apple 6400 appendix Plugging in the computer

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 anything to your Macintosh, follow the instructions in this section on how to plug it in. The plug grounds the computer and protects it from electrical damage while you are setting up.

When you are ready to begin, follow these steps:

1Place the computer where you want it—either on the floor or on a sturdy desk.

If your computer came with a modem, you may want to set your computer near a phone jack (if possible) so that you can connect your modem later.

2Make sure the voltage switch on the back of the computer is set for the kind of voltage system you will be connecting to.

The voltage switch must be set correctly to avoid damaging your computer. If you don’t know the voltage used in the country you’re in, refer to the table “Voltages for Different Locations” later in this chapter.

Before you plug your computer in, check to see that the voltage switch on the back is properly set. If you need to change the setting, insert a small screwdriver here and slide the switch.

Set the switch to show “115” for voltages in the 100–130V range. Set the switch to show “230” for voltages in the 200–270V range.
