Troubleshooting the Modem
My modem does not work.
 Check that the telephone line is plugged into the line jack. See Connecting a Telephone Line for more information.
 Check that the telephone line is working by plugging the line in an ordinary telephone and listening for a dial tone.
 Verify the telephone number the program is dialing is correct.
 Verify the software you are using is compatible with the computer's modem. (All preinstalled Sony programs are
compatible.)
 If you are still experiencing problems, use your the Driver Recovery CD to reinstall the modem drivers. See Using the
Application Recovery CD(s) for more information.
