Chapter 2. Using Your Computer
Using modem port
The modem port supports a standard telephone cable with one RJ-11
connector, and allows dial up access to an internet service provider (ISP).
Important:
Do not connect the modem port to a digital circuit cable, or else the
current in the digital circuit may damage the modem.
To reduce the risk of fire, use only No. 26 AWG or larger (for example,
No. 24 AWG) telecommunication line cord listed by Underwriters
Laboratories (UL) or certified by the Canadian Standards Association
(CSA).
