Communication Functions
This chapter explains how to use the built-in modem, the LAN unit, and the wireless
LAN function.
• When you use communications software:
• Connect your computer to the AC power source.
• Disable power management. (Refer to Disabling Power
Management section of Chapter 3.)
• See also the manual or online help of the software you are using.
• The communication speed may vary depending on the traffic, local
telecommunications infrastructure, and ISP (Internet Service Provider)
infrastructure.
Built-in Modem
You can use the built-in modem for data transfer and fax 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.
• Use TA (terminal adapter) to connect the built-in modem to a digital
telephone line.
• 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.
• Within the communications software you are using, set the COM port
of the built-in modem to COM 3 if required.
• Before commencing with fax communication, it is recommended that
you exit other application programs.
