modem/communication
problems.
1. Make sure the telephone cords are connected correctly
and securely. Connections for a standard modem are
shown in “Disconnecting cables” on page 36. If you are
using other communication devices in conjunction with
the modem, such as an asymmetric digital subscriber
line (ADSL) adapter or home networking adapter,refer
to the documentation for those devices to ensure the
cords are properly connected.
2. Make sure the telephone line works. If you have a
telephone connected to the modem, try making a call. If
you do not have a telephone connected to the modem,
plug a telephone into the same telephone outlet that the
computer is plugged into (remember to reconnect the
computer to the telephone outlet after verifying that the
line is working).
3. Make sure you are calling the correct number and that
you are using the correct communications settings. For
additional help, refer to the documentation for your
communications software.

6. If some communications programs work but others do
not, there might be a configuration problem. For
additional help, refer to the documentation for your
communications software.
7. Make sure your modem cord is attached to an analog
telephone line. The local telephone company can
determine the type of telephone line.
8. Make sure the modem is securely installed inside the
computer.(See “Removing the rear cover” on page 37.)
