Troubleshooting the modem

My modem does not work.

❑Check that the phone line is plugged into the line jack. See “Connecting a Phone Line” on page 62 for details.

❑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 dialing is correct.

❑Check that the software you are using is compatible with the notebook’s modem. (All preinstalled Sony programs are compatible.)

My modem connection is slow.

Your notebook is equipped with a 56K/V.90 compatible modem. Many factors may 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.

❑If you are having a problem connecting with your Internet Service Provider, check that the ISP is not experiencing technical problems.

❑If you have a second phone line available, try connecting the modem to that line.

Troubleshooting audio

My speakers have no sound.

❑If the built-in speakers are turned off, press Fn+F3 to turn on the speakers. You can also turn on the speakers using the Jog Dial control.

❑If the speaker volume is turned to the minimum, press Fn+F4, and then press

➜ or ➜ to increase the volume or you can use the Jog Dial control to control the volume.

❑ If nothing is displayed when you press Fn+F3 or Fn+F4.
