telephone with BLUETOOTH®
wireless technology

Installation
Install the telephone base close to a telephone jack and a power outlet not
controlled by a wall switch. The telephone base can be placed on a flat surface
or vertically mounted on the wall. For optimum range and better reception,
place the telephone base in a central and open location.
You may hear interference if your cellular phone is too close to the telephone
base during a CELLULAR call. Make sure that your Bluetooth enabled cellular
phone is between one to 12 feet away from the telephone base in order
to maintain a clear and consistent connection between your Bluetooth cell
phone, telephone base and cell tower.
If you subscribe to high-speed Internet service (digital subscriber line - DSL)
through your telephone line, you must install a DSL filter between the telephone
base and the telephone wall jack (see the following page). The filter prevents
noise and caller ID problems caused by DSL interference. Please contact your
DSL service provider for more information about DSL filters.
Your product may be shipped with a protective sticker covering the handset or
telephone base display - remove it before use.

HANDSET 1
NOTE: You can only
pair one Bluetooth
cell phone with the
telephone base at a
time.
Bluetooth setup
To use a Bluetooth-enabled cellular phone with
your telephone, you must first pair and connect
your Bluetooth cellular phone with the telephone
base.
Pairing a device
Before you begin, make sure that your Bluetooth-
enabled cellular phone is not connected to any
other Bluetooth device. Refer to your cellular
phone user's manual to learn how to search for or
add new Bluetooth devices.
To pair and connect a cellular phone:
1. Press and hold the Bluetooth button on the
telephone base until it is flashing. The Bluetooth
feature will be activated.
2. Using your cellular phone, turn on the Bluetooth
feature and search for a new device.
3. Once your cellular phone has found the AT&T
DECT 6.0 telephone base, select it.
4. Using your cellular phone, enter the PIN of the
telephone base (the default PIN is 0000) to
continue the pairing process.
When a device is successfully connected, the
status icon will display on the cordless handset
screen, and the light of the Bluetooth button on
the telephone base will be on steadily.
Auto connection
Once you have paired a device with the
telephone base, the pairing information is stored
in the telephone base. If the paired device
becomes disconnected, the telephone base will
automatically search and re-connect to that device.
If the connection does not resume in a minute, you
will need to re-connect to that device manually,
refer to the section below for details.

Bluetooth setup
Manual connection
To manually re-connect a paired device, make
sure the Bluetooth feature is turned on in your
cellular phone, select AT&T DECT 6.0 from the
paired device list in your cellular phone. Once the
connection is established again, the Bluetooth
button on the telephone base will turn back on.
Turning off the auto connection
If you do not want the telephone base to re-
connect to a paired device automatically after
it is disconnected, you can turn off the auto
connection feature manually. In order to turn off
the auto connection, you will need to initiate a
disconnection from the paired cellular phone; this
will transmit a signal to the telephone base and
disable the auto connection.
While the cellular phone is connected to the
telephone base, find the cellular phone’s Bluetooth
device list and select AT&T DECT 6.0 to manually
disconnect the device. (If disconnection is not an
option on your cellular phone, you may need to
disable Bluetooth or unpair the telephone base.)
Refer to your cellular phone’s user’s manual for
instructions. The telephone base will not search
and re-connect to this cellular phone until this
feature is activated again.

Bluetooth setup
To resume the auto connection
To resume the auto connection between the
paired device and the telephone base, you will
need to connect the device manually. Make sure
the Bluetooth feature is turned on in your cellular
phone. Select AT&T DECT 6.0 from the paired
device list in your cellular phone to reconnect.
If the connection is successfully resumed, the
status icon will display on the cordless handset
screen, and the light of the Bluetooth button on
the telephone base will be on steadily.
Replace a paired device
If you want to pair and connect a new device when
there is already a device paired with the telephone
base, press and hold the Bluetooth button on the
telephone base until it is flashing, then start with
step two of Pairing a device on page 6. If you
do not pair a new device within two minutes, the
Bluetooth light on the telephone base will turn off
and the system will return to idle mode.
NOTE: If the connection
between the paired
device and the telephone
base does not resume by
manually connecting the
device on the paired
device list, you will need
to unpair or deregister
the device from the
cellular phone. Make
sure the device is no
longer on the paired list
after deregistration; then
follow the steps in
Pairing a device on
page 6 to start the
pairing procedures again.
