2 Open your communications program and enter terminal
mode.
Terminal mode sends the characters you type on the
keyboard to your modem and displays them on the screen.
3 Try dialing your own telephone number.
If you hear a busy signal, you are properly connected.
4 If you do not hear a dial tone, test your telephone line by
connecting a working telephone and cable to the line.
Plug the telephone into the wall jack to verify the dial tone.
If there is none, the telephone line is the source of the
problem. The telephone line may be a digital line, in which
case the modem will not work.
5 If you hear a dial tone on your telephone but not through
your modem, test your modem’s telephone cable by
connecting it to the wall jack and to the telephone.
If there is no dial tone, the telephone cable is the source of
the problem. Return it to your service provider for
replacement.
6 If your modem still has no dial tone, see the service and
support information that came with your computer for a
number to call.
WARNING If your modem needs repair, take it to an
Apple-authorized service provider. Do not attempt to repair
or reinstall modem hardware yourself.
