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.)

❑

Your notebook is equipped with a V.90/K56flex-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 (ISP), 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.

❑

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.
