❑ 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.
My modem connection is slow
Many factors influence modem connection speed, including telephone line noise or compatibility with
telephone equipment (such as fax machines or other modems). If you think your modem is not connecting
properly to other PC-based modems, fax machines, or your Internet Service Provider, check the following:
❑ Have your phone company check that your phone line is free from any line noise.
❑ If your problem is fax-related, check that there are no problems with the fax machine you are calling and
that it is compatible with fax modems.
