Internet and Fax
The fax/modem RJ-11 jack can transmit data using the 56 Kbps V.90 or V.92 protocol, and send and
receive faxes at 14.4 Kbps. In some countries, local regulations may not permit the use of the
fax/modem designed for this system. In this case, you may use a PCMCIA modem.
CAUTION Plug your modem into an analog telephone jack only. Most homes use analog lines. Do
not use digital lines, such as PBX and ISDN systems found in many offices. Digital lines may damage
your modem. If you are unsure as to the type of port you have to plug into, contact your building
superintendent. Simple detection and protection devices are also available at most computer stores and
should be used to protect the Duo-Touch.
