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. Click start, point to All Programs, point to TOSHIBA, point to
Networking and click Modem Region Select.
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.
4. Select a region from the region menu or a telephony location from the
sub-menu.
■When you click a region it becomes the modem’s region selection,
and the New Location for telephony will be set automatically.
■When you select a telephony location, the corresponding region is
automatically selected and it becomes the modem’s current region
setting.
■Connection to any communication line other than an analog phone line
could cause a PC system failure.
■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 PC on AC power during a thunderstorm. If you see
lightning or hear thunder, immediately turn off the PC. An electric surge
caused by the storm, may result in a system failure, loss of data or
hardware damage.
The built-in modem can be used only in specified countries and regions.
Using the modem in an area not specified for use may cause a system
failure. Check the specified areas carefully before using it.
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.
