Getting started

Pairing the headset with Bluetooth® devices 

CAUTION
Danger of malfunction!
The transmitted radio waves of mobile devices can impair the operation of sensitive and unprotected devices.
 Only use Bluetooth where it is permitted.

The headset complies with the Bluetooth 5.0 standard. Bluetooth devices need to support the “Hands-Free Profile” (HFP), the “Headset Profile” (HSP), “Audio Video Remote Control Profile” (AVRCP) or the “Advanced Audio Distribution Profile” (A2DP).

To transmit data via Bluetooth, you first have to pair your headset to a wireless device. The delivered dongle is already paired with the headset.

The headset can save up to eight paired devices. If you pair the headset with a ninth device, the device with the oldest activity in the pairing list will be overwritten. If you want to re-establish a connection with this device, you have to pair it again.

The headset can be connected to two of the paired devices at the same time. You can only connect another device by disconnecting one of the already connected devices.

Connecting the headset via the dongle 

To connect the headset wirelessly with a computer, use the BTD 800 USB or BTD 800 USB-C dongle.
The dongle and the headset in the bundles are already paired.
Turn the headset on (see page 10).
Plug the dongle into the USB port of your computer.

The dongle LED flashes blue while searching and switches to dimmed blue when connected successfully to the headset.

If Microsoft Teams is invoked: The dongle connects to Teams and lights up purple instead of blue.

The dongle shows Teams notifications.

Pairing the headset via Bluetooth with a mobile device

Press and hold the Power button until the LED flashes blue and red.
The headset is in pairing mode.

Enable Bluetooth on your mobile device and start the search for Bluetooth devices – see instruction manual of your mobile device.

Select “EPOS ADAPT 360” to establish a Bluetooth connection to the headset.

The LED flashes 2 times blue as soon as the headset finds a device to connect to. The LED turns off.

Installing the EPOS Connect software 

The free EPOS Connect software allows you to configure and update your headset and offers additional settings.
Download the software from www.eposaudio.com/connect.
Install the software.
You need administrator rights on your computer – if necessary, contact your IT department.

To make calls via the computer:
Install a softphone (VoIP Software) or ask your admin for support.

Changing Audio settings for the headset – Microsoft® Windows 

Windows usually changes the Audio settings automatically if you connect a new headset.
If the headset is connected but you hear no sound:
Right-click the Audio icon.
Select under output ADAPT 360 as speaker.
Select under input ADAPT 360 as microphone.

Using the headset

Using Active Noise Cancellation (ANC) 

This headset provides attenuation of ambient noise using Active Noise Cancellation (ANC) technology. Special microphones optimize speech and reduce background noise.
