You can pair multiple headsets to your device, but only one can be used at a time. The connection range is up to 10 m (30 ft). If you move outside the range when in a call, the audio switches to the speakers on the device.

Most headsets have built in volume controls. When you’re in a call, the volume of the headset and device is synchronized. Outside a call, the volume buttons on the headset and device operate independently.

You can do the following from your Bluetooth headset:

  • Answer incoming calls

  • Reject incoming calls

  • Hang up calls

  • Volume up and down

  • Some headsets have mute control. This operates independently from the mute control on the device.

USB Bluetooth dongle

It’s possible to connect your Bluetooth headset using a dongle. This gives you better audio quality. On the down side, there’s no synchronization of headset volume and the volume on your Desk device when using a dongle.

To see which Bluetooth dongles we’ve tested and recommend, see USB Headsets and Handsets Supported for DX80 .

Pairing Your Bluetooth Headset

  1. Activate Bluetooth pairing on the headset.

  2. Open the Settings menu on your Desk device and scroll to Bluetooth .

    If Bluetooth is disabled, toggle it ON.

  3. The Desk Pro, Desk Mini, DX70, or DX80 scans for devices. When it discovers the Bluetooth headset, the headset shows up in the device list. Select your headset from the list and the pairing begins. It may take a few seconds for the pairing to complete.

  4. When the pairing is completed, your headset is listed as connected.

Switch Between Devices

You can switch between the speaker on the Desk device, and the devices that are connected through Bluetooth or USB. Select the icon in the status bar on the upper right corner of the touch interface, and choose from the available devices. The icon on the status bar depends on which output your Desk device is currently using.
