Apple Power Macintosh 4400 - Manual (Page 11)

11 Getting Started
You can use any standard phone cord to connect your internal modem
connector to a phone jack. If you have only one phone jack, consider
purchasing a line splitter at an electronics supply store. A line splitter lets you
plug your phone and your modem into the same jack at the same time. Keep
in mind that if your phone and your modem share a single phone line, you
will not be able to use both pieces of equipment at the same time, even if they
are attached to separate phone jacks. When you use your modem, outside
callers get a busy signal and you cannot call out. When your phone is in use,
you cannot use the modem. (By the way, you can keep your answering
machine connected to your phone, even if your phone and modem share the
same telephone line.)
IMPORTANT During lightning storms, disconnect your modem by unplugging its
phone cord from the phone jack to help prevent accidental voltage overload.
Note: It is also possible to use an external modem with your computer.
However, to use an external modem you must first remove the internal modem
card following the instructions in “Installing a Communication Card” in the
section “Installing an Expansion Card,” in Chapter 10 of this manual. You will
also need to remove the cover from the external modem port, so you can
connect the external modem cable.
Connecting other equipment
If you are new to the Macintosh, it’s a good idea to get some experience using
your computer before you connect other equipment, such as a printer or
scanner. To learn basic Macintosh skills, continue with the instructions in
this chapter.
When you’re ready to connect other equipment to your Macintosh, see the
instructions in Chapter 3 and Chapter 4.
