3. Select **Settings**.
4. Select **Push-to-talk buttons**.
5. Select **Add New Device **to display **Headset Button.**

### Mapping a PTT Button to a Contact or Channel

The number of PTT buttons that can be mapped will depend on your accessory's specifications. 

1. Tap your **profile picture **in the top left corner.
2. Select **Settings**.
3. Select **Push-to-talk buttons**.
4. Select an accessory button from the list.
5. Tap either **Contacts** or **Channels** under the button mapping section to display your contacts or channels list.
