If the modem doesn’t dial or no dial tone is detected
•
Check all cables and connections.
•
Connect a standard telephone to the phone line and make sure the line is working.
•
Make sure someone else isn’t using the same phone line.
•
Try another telephone line, preferably one normally used for a fax machine or
modem.
•
If you’re in a foreign country, the dial tone may not be recognized by the modem. In
Control Panel, open Phone and Modem Options. Try disabling the option that waits
for a dial tone.
If the modem dials incorrectly
•
Check the telephone number you entered, including any digits required for outside
access or long distance.
•
In Control Panel, open Phone and Modem Options. Check the dialing options—look
for duplicate digits for outside access or long distance.

instructions.
If the modem dials but doesn’t connect

Make sure you’re using an analog telephone line (2, 3, or 4 wires). You must not use
a digital line. In a hotel, ask for a data line.

modem.

The modem at the other end may have a problem. Try dialing to a different modem.
