6. If the modem comes back with a No Dial Tone message, type the phone
number of a local ISP (Internet Service Provider) or BBS number and press
ENTER.
NOTE: The number in the command code is the actual number to be
dialed.
7. If the modem dials out instead of coming back with a No Dial Tone mes-
sage, you have a non-standard dial tone. At this point you should either
have your phone line checked or try adding X3 to the Extra Settings field.
Access Extra Settings for help locating the Extra Settings field specific to
your operating system.
8. If the modem doesn't attempt to connect and it comes back with a No Car-
rier message, the issue may not be phone line related.
My modem won’t dial out or doesn’t answer incoming calls.
Possible solution: Make sure that you are using the power supply that
came with your modem; other similar-looking power supplies may be of
different voltages and could damage your modem.
Possible solution:
You might have a bad phone cord connected to your
modem, or your phone cord may be plugged into the wrong jack. The phone
cord should be plugged into the jack labelled on the modem and into
the telephone wall jack. Use the phone cord included in your modem’s box,
if possible.
Possible solution:
You may have devices between the modem and the
phone jack. There should be no line splitters, fax machines, or other devices
between the modem and the telephone wall jack.
Office Users
Possible solution: You may have plugged your modem’s phone cord into a
digital line, which can damage your modem. Contact your phone system
administrator if you are unsure whether or not your phone line is digital.
If your phone system requires dialing “9” to access an outside line, be sure
to add “9” before the number you are dialing.
Dialing Problems for Voice Mail Users
Possible solution:
If you have voice mail provided by your local phone
company, your dial tone may be altered when messages are waiting.
