Putting the MM 450 into operation
Pairing the headset with an audio source
̈ Press the Master button ቦ and keep it pressed until the Star LED ቢ
flashes 3 times red.
The headset switches off (see “Switching the headset off” on page 15).
̈ Press the Master button ቦ and keep it pressed until the Star LED ቢ
alternately flashes blue and red.
̈ On your audio source, activate the Bluetooth function “Add a new
device”.
̈ Proceed as described in the instruction manual of the audio source.
If a suitable audio source is found, the devices will exchange device identi-
fication information. The Star LED ቢ flashes 3 times blue and you hear an
ascending beep. The devices have identified each other and the headset is
paired with the audio source.
If a connection is established, the Star LED ቢ continues to slowly
flash blue.
If no device is found within approx. 5 minutes, the Star LED ቢ flashes
3 times red and you hear a descending beep. The headset will then try for
3 minutes to connect to one of the 5 known audio sources. If this fails, the
headset automatically switches off.
̈ In this case, repeat the necessary steps to pair the headset with the
audio source again.
