TOSHIBA Mic Effect
TOSHIBA Mic Effect provides you with a hands-free environment for 
holding mutual communication via the Internet Protocol or Local Area 
Network. If you wish to communicate with someone on your computer, 
you can use a messenger application. However, with such an application, 
you would hear your own voice returning to you as echo during the 
communication if you did not use a headset system or headphone. 
TOSHIBA Mic Effect will reduce these echoes generated on your computer.
To apply the echo cancellation, follow the steps below.
1. Click the right button of a mouse on the speaker icon on the Taskbar, 
and select Playback Devices in the sub menu.
2. On the Playback tab, select Speakers, and click Properties.
3. On the Advanced tab, select “16 bit, 48000 Hz (DVD Quality)” in the 
pull-down menu of Default Format, and then click OK.
4. On the Recording tab, select Microphone, and click Properties.
5. On the Advanced tab, select “2 channel, 16 bit, 48000 Hz (DVD 
Quality)” in the pull-down menu of the Default Format pane.
6. On the TOSHIBA Mic Effect tab, select the Enable Echo Canceller 
check box, and click Apply.
Modem
This section describes how to connect and disconnect the internal modem

Connection to any communication line other than an analog phone line

Connect the built-in modem only to ordinary analog phone lines.
Never connect the built-in modem to a digital line (ISDN).
Never connect the built-in modem to the digital connector on a 
public telephone or to a digital private branch exchange (PBX).
Never connect the built-in modem to a key telephone system for 
residences or offices. 
Never operate your computer on AC power during a thunderstorm. If 
you see lightning or hear thunder, immediately turn off the computer. 
An electric surge caused by the storm, may result in a system failure, 
loss of data or hardware damage.
Modem functions cannot be used in models which are not equipped 
with a modem.
This information is applicable to the models equipped with a built-in
