1.3Installation

1.3.1Identify Your Existing Wiring System

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.

1.3.2Plan Your Installation

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.

1.3.3Standard Installation:

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.

1.3.4Installations with Private Lines and Unconnected Lines:

You may wish to connect private lines to Lines 2, 3 or 4 at some or all of your telephones. Aprivate 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.

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.
