15 I N S T A L L A T I O N Two-Line Phone System A two-line phone system is nothing more than two separate phone numbers on the same wall outlet. The two phone numbers can be on separate jacks (RJ11) or combined into one jack (RJ14). Your FAX/MFC must be plugged into an RJ11 jack. RJ11 and RJ14 jacks may be equal in size and appearance and both may contain four wires (black, red, green, yellow). To test the type of jack, plug in a two-line phone and see if it can access both lines. If it can, you must separate the line for your FAX/MFC. Converting Telephone Wall Outlets There are three ways to convert to an RJ11 receptacle. The first two ways may require assistance from the telephone company. You can change the wall outlets from one RJ14 jack to two RJ11 jacks. Or, you can have an RJ11 wall outlet installed and slave or jump one of the phone numbers to it. The third way is the easiest: Buy a triplex adapter. You can plug a triplex adapter into an RJ14 outlet. It separates the wires into two separate RJ11 jacks (Line 1, Line 2) and a third RJ14 jack (Lines 1 and 2). Plug the FAX/MFC into Line 2 of the triplex adapter. Triplex Adapter RJ14 RJ11 RJ14

INSTALLATION
Two-Line Phone System
A two-line phone system is nothing more than two separate phone numbers
on the same wall outlet. The two phone numbers can be on separate jacks
(RJ11) or combined into one jack (RJ14). Your FAX/MFC must be plugged
into an RJ11 jack. RJ11 and RJ14 jacks may be equal in size and appear-
ance and both may contain four wires (black, red, green, yellow). To test
the type of jack, plug in a two-line phone and see if it can access both lines.
If it can, you must separate the line for your FAX/MFC.
Converting Telephone Wall Outlets
There are three ways to convert to an RJ11 receptacle. The first two ways
may require assistance from the telephone company. You can change the
wall outlets from one RJ14 jack to two RJ11 jacks. Or, you can have an
RJ11 wall outlet installed and slave or jump one of the phone numbers to it.
The third way is the easiest: Buy a triplex adapter. You can plug a triplex
adapter into an RJ14 outlet. It separates the wires into two separate RJ11
jacks (Line 1, Line 2) and a third RJ14 jack (Lines 1 and 2). Plug the
FAX/MFC into Line 2 of the triplex adapter.
