General Troubleshooting Tips
This section presents solutions to some common problems you may experience
when installing your modem. Some solutions may not apply to your operating
system or environment. If you cannot resolve your difficulty, contact your dealer
or vendor for assistance.
Modem Does Not Respond To Commands
•
Verify that the modem is on, receiving power from the USB port.
•
Make sure the modem is plugged into a USB port. Consult your computer
user's manual for the location and function of your installed USB port(s).
•
Make sure the modem is initialized correctly. Issuing AT&F and pressing the
ENTER key will reset the modem to its factory default settings.
•
Make sure the baud rate setting in the communications software is set to the
correct value. An incorrect baud rate prevents the modem from operating
properly.
•
Make sure the phone cable is plugged into the "Line" jack on the back of the
modem.
Modem Does Not Dial
•
Make sure the modem is turned on, and connected to a working phone line.
Replace the modem with a telephone to ensure that the line is working.
Modem Dials But Does Not Connect
•
Make sure the communications software is configured to the same COM Port
and IRQ setting as the modem.
•
Be sure the phone line is working properly. Replace the modem with a regular
phone and dial the number. If the line sounds noisy, you may have difficulty
making data-transfer connections.
Modem Experiences Errors Or Disconnects
•
Make sure the phone line does not exhibit excess noise.
