Epson 4SLC2-50 - Manual (Page 66)

Connecting the Internal Fax/Modem
If the internal fax/modem is installed in your ActionNote
computer, you can connect it directly to your telephone line using
a standard phone jack. The modem will then be ready to use.
Note
If your computer did not come with the internal fax/modem
installed, you must have an Authorized Epson Servicer install it.
If you purchased a fax/modem with your computer, a telephone
cable is included in your package. Insert one end of the modular
jack cable into the LINE port on the left side of the computer and
insert the other end into a modular jack outlet.
If you have a fax/modem, your package also includes BitCom data
communications software and WinFax LITE fax transmission
software already loaded on your hard disk drive. See the
documentation that came with these applications for details on
how to use them.
