For you to properly connect your 2740 4-Line Telephone System to an existing wiring system, it is
important that you understand its configuration. The following are the most common multiple line situations.
They consist of either one or both types of standard telephone jacks: The RJ11 Single Line Jack and the
RJ14 Double Line Jack. Your system should match one of them.

Up to 16 2740 4-Line Telephone System telephones may be connected to form your office/home con-
figuration. Each phone must be assigned a different station number, from 01 to 16. Until a telephone is
assigned a station number, the telephone will not operate. To assign this telephone a station number, simply
press the soft key under CHANGE repeatedly until the desired station number is displayed.

NOTE: Each 2740 telephone must be connected to the same Line 1 telephone number for proper opera-
tion. The remaining lines may or not be connected to each station.

Your 2740 telephones come factory-set for a standard   installation, which is also called “square” in tele-
phone terminology. This means that Line 1 is to be connected to the same Line 1 telephone number at all the
stations, Line 2 is to be connected to the same Line 2 telephone number at all the stations, and so on for
Lines 3 and 4. This is the desired setup for most installations, and if this is how you will be connecting your
2740, you do not need to change any of the line connection settings in the telephones. You need only
connect the phones to the telephone lines.

You may wish to connect private lines to Lines 2, 3 or 4 at some or all of your telephones. A private line is a
telephone number that is connected to only one of the 2740 4-Line Telephone System, and is not shared
with any other station.

1. Select the desired viewing angle and install the desk stand.  The desk stand can be installed in two

positions to give a choice of viewing angle.

2. Connect the power adapter to the jack on the bottom of the phone.   Plug the large part of the adapter

into a wall outlet which is not controlled by a wall switch.  Use only a 9V DC 500mA,  center positive
Class 2 adapter.

3. Connect the line cords.  See Section 1.3.9.
4. Plug the coiled cord into the handset jack, and then plug the other end of the cord into the base.
5. Place the handset on the base.

1. Remove the desk stand.  The unit will then mount directly on a standard wall telephone jack.
2. Connect the power adapter and the line cords. See Steps 2 and 3 above.
