Communication Functions 5-3
Built-in Modem (not available in some
countries)
You can use the built-in modem for data transfer, fax communication and voice
communication.
•
The built-in modem on your computer is designed only for regular
analog telephone lines. The modem may be damaged when connected
to a digital ISDN terminal or a digital PBX.
•
If an unusual device is attached to the line you are connecting to, the
modem may not function properly. Remove the device or contact the
dealer of the device.
•
Before connecting to a PBX, consult the PBX maintenance staff or its
service company. If the electric characteristics of your PBX are
different from those of a regular analog line, the modem will not
function properly. If you connect the modem to a digital PBX, both
the modem and the PBX may be damaged.
Connecting the Modem to a Telephone Line
1. Turn off your computer.
2. Remove the cover of the modem jack on the right side of your computer and
connect the end near the core of the included modem cable to the modem jack.
3. Connect the other end of the cable to the telephone line.
4. Turn on the computer.
Connect the modem to the telephone line directly. Do not use a
distributor or allotter.
