The headset can save the connection profiles of up to eight Bluetooth devices
with which it has been paired. After switch-on, the headset automatically tries
to connect to the two last connected Bluetooth devices. You can only connect a
third Bluetooth device after having switched off the first or the second Bluetooth
device.

tion with the first/PRESENCE this Bluetooth device, you have to pair the headset
again.
