Troubleshooting the modem

My modem does not work
❑
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 / Phone and Modem Options), check that your modem is listed
in 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.
❑
A country-specific phone plug is supplied with your VAIO computer, allowing you to plug the phone line into the wall jack.
We recommend you to use the supplied plug, because the usage 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.
❑
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 in the Software Guide.
❑
Do not pull the flexible cover too forcefully.
