1.3 Installation
1.3.1 Overview
The 2750 is part of the 7 Series Multiline phone system. Up to 16 instruments may be connected in
this system. All these devices use conventional telephone wiring. Wiring runs between stations may be
a maximum of 600 feet.
1.3.2 Before Installation
In order to install your telephones correctly, you must determine the incoming wiring configuration. In
most cases, incoming lines will be terminated in either RJ11 Single Line Jacks or RJ14 Double Line
Jacks. If you are not sure of your incoming line configuration, contact your telephone line installer.
All connection between the wall jacks and the telephones may be done with standard telephone
modular cords. Please be sure that your modular cords have at least 4 wires in them.
If you have RJ11 jacks, you will need two line adapters (not included) to connect to the 2750. These
couplers take the single line wiring and convert it to double line wiring. These couplers should be
available where you purchased your 2750.
1.3.3 Installation Configurations
1.3.3.1 Standard Configuration
The 2750 is initially configured so that each line is common at all stations. In other words, Line 1 at
each telephone is connected to the same incoming line; Line 2 at each station is connected to the same
incoming line, etc. This is commonly known as a “square system.” If this is suitable for your
installation, you only need to connect the telephones to the telephone lines.
1.3.3.2 Private Line
A private line is connected to only one telephone in the system. No other phones in the system have
access to this telephone line.
1.3.3.3 Unconnected Lines
It is also permissible to leave one or more lines unconnected.
1.3.3.4 Line 1
Line 1
MUST
be connected to the same incoming line on all phones for the system to function
correctly.

1.3.4 Phone Installation
1.3.4.1 Desk Mount
a. Connect the power adapter to the jack on the bottom of the phone. Plug the adapter into a wall
outlet which is not controlled by a wall switch. Use only a 9V DC 500mA, Class 2 adapter.
b. Connect the line cords. If you have RJ14 line jacks, you need only connect 4 wire line cords
between the wall jacks and the jacks in the base of the 2750. If you have RJ11 line jacks, you
will need 2 line couplers as discussed in Section 1.3.2. Note that the jacks on the 2750 are
numbered L1/L2 and L3/L4. Connect your incoming lines accordingly.
c. 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.
d. Plug the coiled cord into the handset jack, and plug the other end of the cord into the base.
e. Place the handset on the base.
1.3.4.2 Wall Mount
a. Remove the desk stand. The unit will then mount directly on a standard wall telephone jack.
b. Connect the power adapter and the line cords. See Steps “a” and “b” above. Use the included
short line cord to connect to the mounting jack. Use one of the included long line cords to
connect to the other jack.
c. Mount telephone to wall jack (RJ-11W).
d. Plug the coiled cord into the handset, and then plug the other end of the cord into the base.
e. Rotate the handset hook into the wall mount position and place the handset on the base.
1.3.4.3 Install Batteries (Optional)
The 2750 uses AC power from a standard wall outlet. As long as the telephone is connected to a wall
outlet, it will operate using the AC power.

features on the 2750. Refer to Section 2.1 for detailed instructions on assigning station numbers.
1.3.5 Test Installation
This procedure should be used at each telephone after initial installation. It may also be used if you are
having problems with your system. First, verify the three items below at each telephone in the system.
a. Verify that the AC power transformer is connected to the 2750 and to mains power.
b. Verify that Line 1 is connected to the 2750.
c. Verify that a station number has been assigned.
Now, verify that Line 1 has been connected correctly to all telephones.
d. Press Line 1 at one telephone.
e. Verify that the Line 1 LED is Green, the Speakerphone LED is red and that dial tone is heard.
f. Verify that the Line 1 LED is red at each other station.
To verify the connection of lines 2 – 4, perform the following steps at each telephone.
a. Press Line 1.
b. Verify that the Line 1 LED is Green, the Speakerphone LED is red and that dial tone is heard.
c. Dial the telephone number for Line 2. Verify that the Line 2 LED flashes slowly. If it does not
flash, Line 2 may not be properly connected.
d. Repeat the steps above using the telephone numbers for Lines 3 and 4 if applicable. Remember

2.3 Line Configuration/Type
While Line 1 must be shared at all stations, Lines 2, 3 or 4 may be unconnected or may be connected to
private lines.
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.
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 common Line 3. In this example, you
would set Line 3 at your station as PRIVATE.
UNCONNECTED:
Use this setting at any telephone that is not physically connected to all of its lines.

detector setting may need to be adjusted. The factory setting of 48 volts is appropriate for most
