22.4 Bluetooth Headset
Note: Before you can connect a Bluetooth headset to your phone, Blue-
tooth functionality must be available in the phone. Bluetooth is
factory-mounted on the circuit board of the phone.
The Bluetooth technology replaces the cord between a cordless phone
and the headset. This allows the user to move more freely and elimi-
nates the risk of a headset cord getting stuck.
Note: Bluetooth headsets are neither provided with nor sold together
with the phone.
The following functions are available:
• Pairing the cordless phone with its headset.
• Choosing the device to use when making a call.
• Playing a ring signal through the Bluetooth headset.
• Answering and connecting sound to the Bluetooth headset when
answering with the headset button.
• Ending a call with the Bluetooth headset button.
• Transferring audio to and from the Bluetooth headset during a call,
using the menu in the cordless phone.
• Increasing and decreasing the volume in the Bluetooth headset
with the volume buttons on the cordless phone.
Note: The Bluetooth headset functions may vary. See your Bluetooth
headset manual.
The cordless phone is tested with a number of Bluetooth headsets.
Since the Bluetooth supports the Bluetooth 2.0 standard, other headsets
may also work although this has not been verified by Aastra.
22.4.1 Using a Bluetooth Headset
For optimal performance, place the Bluetooth headset and the phone on
the same side of your body. The best audio quality in the headset is
achieved when there is no obstructions, including your body, between
the headset and the cordless phone.
22.4.1.1 Activating a Bluetooth Headset
Enabling, disabling, and connecting a Bluetooth headset is explained in
