Chapter 20
Using Accessories and Bluetooth
This section describes using accessories and Bluetooth associated with the Push-to-Talk (PTT)
application and is organized as follows:
Using a Wired Audio Headset on page 145
Using Bluetooth on page 145
Using a Remote Speaker Microphone on page 146
20.1
Using a Wired Audio Headset
You can use a headset plugged into your phone for Push-to-Talk (PTT) calls. Whenever you connect
the headset, PTT calls are heard automatically over the headset instead of the loudspeaker. You must
still use the PTT button on the phone to take the floor to speak, even if your headset has a multimedia
control button on it. When you disconnect the headset, the loudspeaker is used again for PTT calls.
20.2
Using Bluetooth
By default, whenever your phone connects to a compatible Bluetooth device, the PTT application uses
that Bluetooth device for calls. If you turn off or unpair your Bluetooth device, the PTT call automatically
switches to the loudspeaker. The PTT application supports the following Bluetooth profiles: Hands Free
(HFP), Headset (HSP), and Advanced Audio Distribution Profile (A2DP). When using PTT over
Bluetooth, you must use the PTT button on the phone to take the floor and speak.
20.2.1
Car Kit
Many cars allow you to connect your phone to the car audio system using Bluetooth. Check the
owner’s manual for your car to see if your phone is compatible with your car. Once you connect your
phone to the car’s audio system, PTT calls also use the Bluetooth audio. You must use the PTT button
on the phone to take the floor.
20.2.2
External PTT Button
You can use a compatible Bluetooth Smart (Low Energy Bluetooth) PTT button with your PTT service.
This button can be used in addition to the on-screen PTT button.
20.2.3
Bluetooth for PTT
If your phone can connect to your car audio system and you receive regular cellular calls, PTT calls
also work. In the rare circumstance that there is a compatibility problem using PTT with your car audio,
but you still want to use Bluetooth for regular cellular calls, you can turn off PTT over Bluetooth from
within the PTT application settings. For details on how to turn off Bluetooth, refer to the
Using
Bluetooth on page 159
section.
