1.3 Installation
1.3.1 Identify Y our Existing Wiring System
For you to properly connect your 2740 4-Line T elephone 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.
1.3.2 Plan Y our Installation
Up to 16 2740 4-Line T elephone 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.
1.3.3 Standard Installation:
Y our 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.
1.3.4 Installations with Private Lines and Unconnected Lines:
Y ou 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 T elephone System, and is not shared
with any other station.
1.3.5 Desk Mount
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.
1.3.6 Wall Mount
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.
8
3. Rotate the handset hook into the wall mount position.
4. Plug the coiled cord into the handset, and then plug the other end of the cord into the base.
5. Place the handset on the base.
1.3.7 Assign a Station Number
Refer to Section 2.1 for detailed instructions on assigning a station number.
1.3.8 Install Batteries (Optional)
While it is not necessary for you to install batteries in your 2740 telephone for it to function normally , we do
recommend that they be installed. The batteries are not needed to preserve your memory dial numbers,
because all memory dial numbers are stored in static memory . The purpose of having batteries installed is so
that the telephone itself can function for up to two hours in the event of a power failure. The telephone uses
3 AAA size batteries. W e recommend using alkaline batteries.
1. Make sure the AC cord remains attached to the telephone and to an electrical outlet
2. Turn the telephone over.
3. Remove the desk stand if attached.
4. Remove the battery door by using the tip of a ball point pen, paper clip, or similar object to release
the battery door tab.
5. Remove the old batteries.
6. Insert 3 pieces of new size AAA 1.5V alkaline batteries. Please note the “+” and “-” markings in
the battery compartment for the orientation of the batteries.
7. Close the battery cover.
Use caution when disposing of old batteries. Do not dispose of them in a fire. They may explode.
9
1.3.9 Connect Cords to T elephone
If the wall jack is labeled Lines 1 & 2, connect the short telephone line cord to the jack on the telephone
labeled L1/L2. If the wall jack is labeled Lines 3 & 4, connect the short cord to the jack on the telephone
labeled L3/L4. Connect the long telephone line cord to the other line jack on the telephone and thread it
through its long groove on the bottom of the phone, then plug the AC power cord into the adapter jack on
the bottom of the telephone, threading the power cord through its long groove on the bottom of the phone.
Thread the short telephone cord through the square hole in the center of the wall mount bracket, and then
attach the wall mount bracket to the base of the telephone.
1.3.10 Verify Proper Installation
The following procedure should be used at each telephone to check for proper installation. Also use this
procedure any time you are experiencing difficulty . The phone must be connected to the AC power supply ,
line 1 must be connected to the line 1 jack, and the phone must have been assigned an intercom station
number.
First, verify that line 1 is connected to the same telephone number at all the telephones. T o do this, press the
line 1 button at one of the telephones. The line 1 LED should be green, the speakerphone LED should be
red, and dial tone should be heard from the speaker. Now go to each of the other stations and make sure
that each line 1 LED is red. Next, make sure that lines 2, 3 and 4 are connected the same at all the phones
by performing the following steps at each telephone:
1. Press the line 1 button. The line 1 LED should be green, the speakerphone LED should be red, and
dial tone should be heard from the speaker.
2. Dial the telephone number for line 2. The line 2 LED should flash slowly. If the line 2 LED does not
flash, then line 2 is improperly connected to this telephone.
3. If this telephone utilizes line 3 and/or line 4, repeat steps 1 and 2, substituting the respective phone
number(s) in step 2.
2. SYSTEM PROGRAMMING

2.3 Line Configuration
While you must share the same Line 1 telephone number at all the stations, you may choose to leave some
lines unconnected at particular stations or to connect private or auxiliary lines to Lines 2, 3 or 4 at particular
stations.
2.3.1 COMMON
This is the factory setting for all lines. This setting assumes that the line is connected to the same telephone
number at all stations.
2.3.2 PRIVATE
Use this setting at any telephone that is connected to a different telephone number than the corresponding
line at the other stations.
For example, you may connect your private telephone number to Line 3 at your station instead of connecting your station to the shared Line 3. In this example, you would set Line 3 at your station as PRIV ATE.
2.3.3 UNCONNECTED
Use this setting at any telephone that is not physically connected to all of its lines. For example, you may
install a 2740 4-line telephone in a room that is currently wired for only lines 1, 2 and 3. In this example, you

Y our 2740 telephone will light up its line status indicators when a non-2740 telephone such as a fax machine, modem, or standard telephone is using a line.
Note: If the line status indicators of your 2740 telephones do not function properly, either failing to light up
when a standard telephone uses a line, or staying lit even though no telephone is using a line, the loop
voltage detector setting needs to be adjusted.
The factory setting of 48 volts is appropriate for most installations. If this is not suitable, try setting
your phone to 24 volts. If that does not work, then set it to 12 volts. You can also turn this feature OFF if
you prefer.
If a line indicator at your 2740 telephone stays lit because there is no telephone line connected,
and you wish to turn it off, do not use this feature, but set this line at this station to UNCONNECTED
2.5 Ringer Configuration
The ringers for each outside line are controlled individually at each telephone. There are three possible
settings for each line ringer:
RINGER ON: The line will ring normally .
DELA YED RING: The line will start ringing after the first 20 seconds. This is useful for an office where the
phone is normally answered at a central location.
RINGER OFF: The line will not ring.
In all these cases, the line indicators will flash to signal an incoming call. Y ou can always answer a ringing
line, whether or not it is ringing audibly at your telephone, by pressing the corresponding flashing line button.
