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.

• Make sure the number you’re calling isn’t busy.

• 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 you have call-waiting, disable it—your telephone company can provide

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.

• Try another telephone line, preferably one normally used for a fax machine or

modem.

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

• Try disabling error correction and data compression.

If the modem isn’t detected

• Check the modem setup. In Control Panel, open Phone and Modem Options. Check

the COM port.
