Pairing the MB 660

 

Whenever pairing a headset, the first step is to place the headset into pairing mode. Once the headset is in pairing mode, you will need to follow the pairing steps for the end-device you wish to connect the headset to. 

 

 

 

Placing the MB 660 into pairing mode

To place the MB 660 into pairing mode, first switch the headset on. 

Next, press and hold the sound effect mode button for approximately 4 seconds, or until you hear the voice prompt "pairing". 

The LEDs on the headset should now be lighting up in a cascading sequence, indicating that the headset has been successfully placed into pairing mode. 

 

 

Pairing the headset with a smartphone or other Bluetooth enabled device

Once you have confirmed that the headset is in pairing mode, you will need to complete the pairing process on the end-device you wish to connect to. 

Within the device's menu, ensure that Bluetooth is enabled and then search for new Bluetooth devices. You should then be able to see all active devices in your vicinity. 

Find and select your MB 660. You may be prompted to enter a PIN - if this is the case, enter the default Sennheiser PIN "0000".

Once pairing is complete, the LED should flash white three times. 

 

 

Pairing the headset with the BTD 800 dongle 

Once you have confirmed that the headset is in pairing mode, you will need to place the dongle itself into pairing mode as well. 

To do so, ensure that the dongle is inserted and then press and hold the button for approximately three seconds, or until the LED begins to alternately flash red and blue. 

After placing both devices into pairing mode, they should then pair with one another. When pairing is successful, the LED on the headset should flash white three times and the dongle will flash blue three times. If the LED flashes red three times, pairing has failed and the process should be repeated. 

 

 

Clearing the pairing history

Once you have confirmed that the headset is in pairing mode, press and hold the sound effect mode button for another 4 seconds, until you hear the voice prompt "pairing list cleared".

The headset will now re-enter pairing mode and may be paired with your chosen end-device.
