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 (ISP), 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 you are using an external microphone, check that the microphone is 
plugged into the Microphone connector. See “Connecting an External 
Microphone” on page 53 for details.
