Troubleshooting and Maintenance
Troubleshooting Your Computer
• 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.
• Open the hardware Device Manager: click Start, Control Panel, Performance and
Maintenance, System. If the modem is disabled, try to enable it. If it has a conflict, try
disabling another device.
• If you're running fax software using fax Class 2, try using Class 1.
If the modem dials but you can't hear it
• If your model has an audio mute light, make sure it is turned off. If it's on, press the
audio mute button.
• Check the speaker volume setting.
• In Control Panel, open Phone and Modem Options. Select the modem and click
Properties, and then check the volume setting on the General tab.
If the modem connects, but transferred data is bad
• In Control Panel, open Phone and Modem Options. Make sure the parity, speed, word
length, and stop bits match on sending and receiving modems.
• Try disabling error correction and data compression.
