Macintosh Modems

Basic Troubleshooting Steps

1. Is your modem turned on? When your modem is properly connected to power and is turned on, the TR and CS lights on the front
panel will be on.
2. Is your power supply connected properly to both your modem and an electrical outlet? You must use the power supply that came
with your modem; other similar-looking power supplies may be of different voltages and could damage your modem. When your
modem is properly connected to power and is turned on, the TR and CS lights on the front panel will be on. If they are not, check
your outlet with another electrical device to be sure you are getting power.
3. Are you using the proper cable to connect your modem to your computer? Make sure you are using a hardware handshaking
cable, which is packaged with your modem.
4. If there are DIP switches on the back of your modem, are they set correctly? DIP switches 1, 3, 5, and 8 should be in the down
position. See the diagram below for the proper settings.
5. Is your phone cord properly connected? The phone cord should be plugged into the
phone. Use the phone cord included in your modem's box if possible.
6. Make sure you are using the proper cable, and that it is connected to the proper port on the back of your Macintosh. This modem
requires a hardware handshaking cable, which is packaged with your modem. Make sure it is connected to the modem port on the
back of your computer and not the printer port.
