Installing the Base Station
This section describes the base station and:
 how to mount the base station on a wall
 what programming is required before you connect the base station to 
your system
 how to connect the base station to your system
The T7406 cordless telephone operates on the same principle as a two-
way radio. Therefore, the location of the base station affects the range 
of reception. The base station should not be installed where radio waves 
are blocked or reflected, such as next to a filing cabinet.
For optimal performance, install the base station at least 2.4 meters 
(eight feet) above the floor and at least 3.2 meters (ten and one half 
feet) apart from a second base station. Always position the antenna at a 
90° angle to the base station.
Base Station Features
This section illustrates the base station for the T7406 system.

T7406 Pre-installation Programming
Before connecting the T7406 base station to your system, you must set 
up system programming for the handset lines.
Have the system administrator set up this programming:
1. Program Handsfree to Auto.
2. Program a maximum of three lines to each handset.
3. Assign Ring & Appear on the lines you assign to the handset. 
Note: Appear only does not allow the handset to wake from 
Handset Asleep mode.
4. Set the Page zone to None.
Note:Handsets can send Page announcements, but they cannot 
receive them.
5. Set DND on Busy to Yes if you do not want your calls 
interrupted with a ring tone when a second call comes in. Instead, 
the button flashes, indicating an incoming call.
6. Other telephone programming is the same as for the M7310 
telephone, with the exception of the memory key locations.

standby time up to 72 hours. Using the backlight shortens talk and 
standby time.
Handset Configuration 
This section describes how to set up handsets on a base station. Note 
that there is one extra step for setting up the first handset on a new base 
station.
Impor tant First-time Installation Information
When performing the initial configurations on the handset, ensure that 
all the handsets you intend to configure have fully-charged battery 
packs installed.
Since the handsets start scanning as soon as they are powered, you must 
set the handset ID #s first when you configure the handset to avoid 
conflicts between handset signals and the possibility of one set 
mirroring another.

If you install more than one base station on a system, ensure that you 
assign a unique Security code to each base station. However, all base 
stations have the same three Handset ID numbers (1, 2, or 3), which 
identify the handset to the base station.
Identifying the Handsets to the System
Each of the three handsets registered to a base station share an identical 
Security code, but each handset has a unique handset ID number of 1, 2, 
or 3. 
The handset ID number the handset is assigned to maps back to the 
TCM/RJ-11 jack on the back of the base station. The diagram below 
identifies which jack supports which handset ID number.
In turn, these numbers correspond to telephone records in the main 
system. In the system, these records identify each telephone with a local 
number, referred to as a DN (directory number). Since the records will 
be set up before you configure your handset, check with your system 
administrator to determine which local has been assigned to which port. 
From there, you can identify which Handset ID number should be 
assigned to each handset.
Note:When a base station is relocated, the Handset ID number follows 
the set DN (system telephone record), if the Set relocation feature 
is on.

Assigning the Handset to the Base Station
When you assign the first handset to a base station, you must send the 
security code to the base station. For subsequent handsets, you only 
need to identify the security code on the handset itself. This is 
explained in detail in later sections.
This is the general process for setting up a T7406 handset:
 Identify the handset to a unique Handset ID # (1, 2, or 3)
Note:The handset ID #, which gets assigned to each handset, 
matches up to TCM/RJ-11 jack on the back of the base . 
station. Ask your system administrator which handset ID 
maps to which set DN on the system.
 Change the default password for selecting a handset ID (default: 
000000)
 Assign a Security code (S.S. code)
 Send the Security code from the handset to the base station
Note:Sending the security code to the base station is only 
performed for the first handsets. For subsequent handsets, 
you need only identify the security code on the handset.
 Assign the ring type
 Assign the ringer volume
 Assign the language that appears on the handset display

battery charge icon.
Configuring the First Handset to a Base Station
When you configure a handset to a new base station, you must ensure 
the base station receives the assigned security code. For subsequent 
handsets, the security code must be identical, but it does not need to be 
re-assigned to the base station. 
Other settings are the same for all handsets.
Configuring the Handset ID Number
Each of the three handsets registered to a base station share an identical 
Security code, but each handset has a unique Set ID of 1, 2, or 3. 
Follow these steps to set the handset ID and new password:
1. Press the Options button.
2. Press 


.
3. Press 
 until the display shows 	.
