T7406 Cordless Telephone
The T7406 is a multiple handset, single base cordless telephone
system with full mobility integration into your Norstar key system.
The T7406 offers the following features;
Range
The effective operating radio range depends on the building construction and
internal layout of the facility. A typical office or warehouse environment has an
effective operating range of 95 meters(300 feet).
Audio Performance
T7406 uses advanced digital frequency hopping spread spectrum (DFHSS)
technology to provide a quality audio path over a 900 MHz radio link.
Security of Conversation
Each Base has a unique Security Code (S.S. Code). All handsets registered to that
base must share the same 6 digit Security Code. Each handset must also have a
unique set identification (Set I.D.’s #1 to 3). A maximum of three handsets can be
registered to one base.
When viewing the base station from the rear, the TCM jacks running from left to right
correspond to the Set I.D.#s 1 to 3. The Set I.D.’s map to the Port/DN on the system.

Density and Interference
Each base can support up to 3 handsets. Each base has up to 3
independent time compression multiplexing ( TCM ) line
connections to ports on the KSU / system. To avoid interference,
install only 2 bases and 6 handsets per location.
Each base uses half of the Industrial Scientific Medical ( ISM ) band
for its frequency hopping channels. The dip switches on the base
allow you to assign the base to use either the lower half (902-
915MHz) or upper half (915.1- 928Mhz). Each base must use a
separate half of the ISM band.
If other devices operating on the ISM band interfere with the T7406
base, the other half of the band may be used to minimize
interference. In this situation, install only 1 base station and 3
handsets per location.

The following in an example of an installation of the T7406
solution. There are 3 TCM loops going to each Base. The
bases should be a minimum of 20 feet apart as well as 8 feet
off the ground for improved performance. The T7406
solution will operate on any Norstar KSU including the BCM.

Installation
Before beginning installation, make sure that each T7406 set has one fully
charged battery to operate.
Begin the installation by locating an area where your radio will have
optimal performance. The base should not be installed where radio waves
are blocked or reflected, such as next to a filing cabinet. You can test this
by installing a base station in the proximity of your users and testing the
range available from that location. For best results, locate the base within
line of sight of the users, and at least eight feet off the ground. If two base
stations are being installed, place the bases a minimum of 20 feet apart.
Once your optimal location has been located, you can begin the
installation. You have the option of installing the Radio Base horizontally
on a surface in the workspace, or wall mount the Base. In either case, keep
the Base antenna at a 90 degree angle from the base.
Note: You will need to drop 3 TCM loops to the location of the Radio Base.
You will also require power to the Base.

Installation
Connect the Line Cord(s) into the
telephone jacks on the Base. Connect the
other end into the a telephone port on the
KSU
Note: Connect one line cord for each
handset. Maximum of 3 per base.
Plug the small end of the power adapter
into the back of the base. Plug the power
adapter into an AC outlet.
Setting the Dip Switches
On the first base, set the dip switches to
operate in the upper half of the ISM band.
From left to right, the dip switch settings
are Down-Up-Down.
On the second Base, set the dip switches
to operate in the lower half of the ISM
band. From left to right the dip switch
settings are Down-Down-Up.

Handset Setup
Before you begin programming your T7406 sets you
MUST make sure that the ports that these sets will
occupy has “Handsfree” set to “Auto”, this is so that
there will be 2 Intercom Keys on the T7406 set. A
maximum of 3 lines can be programmed for the T7406.
Button Mapping will be explained later
.
There are several steps you must take to set up a
T7406 handset.
•Assign a Security Code
•Send Security Code from first handset to the base.
•Configure the handset identification
•Assign the ring selection
•Assign the ring type
•Assign the ring volume
•Assign the language that appears on the handset
display
Each set must be registered to a base by sharing an
identical Security Code. Each handset must have a
unique Set ID, ranging from 1 to 3. If you have already
assigned the Security code to the base, all you need to
do is assign the same security code to your handset
and then the unique Set I.D. # (range is 1 to 3).
