Troubleshooting the modem

My modem does not work or cannot establish a connection

❑Check that the phone line is plugged into your computer.

❑Make sure that the modem is the only device connected to your phone line.

❑Check that the phone line is working. You can check the line by plugging in an ordinary phone and listening for a dial tone.

❑Check that the phone number the program is dialling is correct. The modem dialling mode may be incompatible with your telephone line.

❑The modem may not work properly if you are with a Private Automatic Branch eXchange (PABX).

❑In the Phone and Modem Options dialog box (Control Panel / Printers and Other Hardware / Phone and Modem Options), check that your modem is listed on the Modems tab, and that the location information is correct on the Dialing Rules tab.

If you do not see the Phone and Modem Options icon, click Switch to Classic View on the left side.

❑We recommend you use country-specific phone plug to plug the phone line into the wall jack, because use of any other phone plug can decrease the connection quality.

❑Your computer cannot be connected to a coin-operated telephone, and may not work with multiple phone lines or a private branch exchange (PBX). If you connect the modem to a parallel connected phone line, the modem or the other connected device may not function properly. Some of these connections may result in excess electrical current and could cause a malfunction in the internal modem.

❑Only DTMF (Dual Tone Multi Frequency) signalling (tone dialling) is supported.

❑The internal modem is intended to be used for data and fax communications using DTMF (Dual Tone Multi Frequency) signalling (tone dialing) on the PSTN (Public Switched Telephone Network) networks in the following countries: Austria, Belgium, Czech Republic, Denmark, Finland, France, Greece, Germany, Iceland, Ireland, Italy, Luxembourg, Norway, Portugal, Spain, Sweden, Switzerland, the Netherlands and the United Kingdom.

❑Before using the modem, it will be necessary to select the country where you are actually using it. The detailed procedure for selecting your present location is explained in Configuring your modem (page 146).

❑If your computer is equipped with the flexible modem connector cover, do not pull it too forcefully.
