❑

If the speakers use an external power source, make sure that the power cord 
is plugged into a grounded wall outlet or power strip.

❑

If the speakers have their own volume control, check the volume level.

❑

If the program you are using has its own volume control, check that the 
volume is turned up.

❑

Check the volume controls in the application, in the audio mixer, and in 
Windows. There is a volume control 

 on the Windows

®

 taskbar. Click the 

icon and slide the level bar up to increase the volume.

❑

Check that the Mute check box is not selected in the Windows volume 
control . 

❑

If you connected headphones to the computer, you will not hear sound from 
the speakers. 

The computer’s modem uses Lucent technology/V.90. 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.

❑

For optimum performance, ensure you are calling an Internet Service 
Provider number that is V.90-compliant.

❑

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 this 
line.

❑

Check that the phone line is plugged into the LINE jack.

❑

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.
