My speakers have no sound

 If the speakers have a mute button, make sure it is off.
 If the speakers are powered by batteries, check that the batteries are inserted properly and that
they are charged.
 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

the volume.

My modem connection is slow
The computer's modem uses Lucent 1648 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.
 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.
My modem does not work
 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.
 Verify that the software you are using is appropriately configured to recognize and interact with
the Sony computer modem. Call the software publisher if you do not know how to configure the
software to recognize the modem. All programs, preinstalled by Sony, are compatible.
 If you suspect your modem is not functioning, you can perform a simple test to find out. Click the
My Computer icon on your desktop. Click Control Panel, and the click Modems. Click the
Diagnostics tab and select COM2. Click More Info. If your modem is functioning, a More Info dialog
box will display. If your modem is not functioning, an error message will appear.
I cannot change my modem to rotary/touch-tone dialing.
Click the My Computer icon on your desktop. Click Control Panel, and then click Modems. Click
Dialing Properties. Next to "Dial using," select the Tone dial or Pulse dial radio button. Click OK.
