Troubleshooting and Maintenance
Troubleshooting Your Computer
•
In Control Panel, open Modems (Windows 98) or Phone and Modem Options
(Windows 2000 or XP). 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 Modems (Windows 98) or Phone and Modem Options
(Windows 2000 or XP). 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 Modems (Windows 98) or Phone and
Modem Options (Windows 2000 or XP). Check the COM port.
• Open the hardware Device Manager: click Start, Settings, Control Panel, System
(Windows 98 or 2000) or Start, Control Panel, Performance and Maintenance, System
(Windows XP). 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
• Make sure the audio-off light is turned off. If it's on, press the audio-off button.
• Check the speaker volume setting.
•
In Control Panel, open Modems (Windows 98) or Phone and Modem Options
(Windows 2000 or XP). Select the modem and click Properties, then check the
volume setting on the General tab.
