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 as detailed below:
1. Click Start → All Programs → TOSHIBA → Networking → Modem
Region Select.
2. The Region Selection icon will appear in the Windows Taskbar.
■ Connection to any communication line other than an analog phone line
could cause a computer 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.
■ Avoid using your computer modem with the telephone cable connected
during an electrical storm. There may be a remote risk of electric shock
from lightning.
Modem functions cannot be used in models which are not equipped with a
modem.
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.
If it is available, do not use the Country/Region Select function included as
part of the modem setup utility within the Control Panel - if you change the
country/region setting this way you may find that the change does not take
effect.
