Operating Basics

Using the microphone

Your computer has a built-in microphone that can be used to record

monaural sounds into your applications. It can also be used to issue voice

commands to applications that support such functions.
Since your computer has a built-in microphone and speaker, “feedback”

may be heard under certain conditions. Feedback occurs when sound from

the speaker is picked up in the microphone and amplified back to the

speaker, which amplifies it again to the microphone.
This feedback occurs repeatedly and causes a very loud, high-pitched

noise. It is a common phenomenon that occurs in any sound system when

the microphone input is output to the speaker (throughput) and the speaker

volume is too loud or too close to the microphone. You can control

throughput by adjusting the volume of your speaker or through the Mute

function in the Master Volume panel. Refer to your Windows documentation

for details on using the Master Volume panel.

Modem

This section describes how to connect and disconnect the internal modem

to and from a telephone jack.

Region selection

Telecommunication regulations vary from one region to another, so you will

need to make sure the internal modem’s settings are correct for the region

in which it will be used.
To select a region, follow the steps below.
1. In Windows XP, click start, point to All Programs, point to TOSHIBA,

point to Networking and click Region Select Utility.

2. The Region Selection icon will appear in the Windows Task Bar.
3. Click the icon with the primary mouse button to display a list of regions

that the modem supports. A sub menu for telephony location

information will also be displayed. A check will appear next to the

currently selected region and telephony location.

The internal modem does not support voice functions. All data and fax

functions are supported.

In case of a lightning storm, unplug the modem cable (optional) from the

telephone jack.
Do not connect the modem to a digital telephone line. A digital line will

damage the modem.

Do not use the Country/Region Select function in the Modem setup utility

in the Control Panel if the function is available. If you change the Country/

Region in the Control Panel, the change may not take effect.
