Pairing the headset with Bluetooth devices
CAUTION
Danger of malfunction!
The transmitted radio waves of mobile phones can impair the operation of sensi-
tive and unprotected devices.
X Only make calls with the headset in locations where wireless Bluetooth trans-
mission is permitted.
The headset complies with the Bluetooth 4.0 standard. In order that data can
be transmitted wirelessly using Bluetooth technology, you have to pair your
headset with Bluetooth devices that support the “hands free profile” (HFP), the
“headset profile” (HSP) or the “advanced audio distribution profile” (A2DP).
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.
If you pair the headset with a ninth Bluetooth device, the saved connection
profile of the least used Bluetooth device will be overwritten. If you want to re-
establish a connection with this Bluetooth device, you have to pair the headset
again.

tooth or an additional Bluetooth USB dongle (wireless audio transmitter and
receiver). The BTD 800 USB Bluetooth USB dongle is supplied together with the
MB Pro 1 UC/MB Pro 2 UC variants and is pre-paired with the headset.
To use the headset with a Bluetooth USB dongle:

struction manual of your Bluetooth USB dongle.

If you are out of the Bluetooth transmission range
Calling is only possible in the Bluetooth transmission range of the mobile phone/
Bluetooth device. The transmission range largely depends on environmental con-
ditions such as wall thickness, wall composition etc. With a free line of sight, the
transmission range of most mobile phones and Bluetooth devices is up to 10
meters.
If the headset leaves the transmission range of the connected Bluetooth device
during a call, one of the following voice prompts is announced in the headset:
• “Phone one disconnected” for the first mobile phone
• “Phone two disconnected” for the second mobile phone or
• “Dongle disconnected” for the Bluetooth dongle.
If you re-enter the Bluetooth transmission range within these 5 minutes, the con-
nection is re-established and the voice prompt “Phone one connected”, “Phone
two connected” or “Dongle connected” is announced in the headset.
If you spend more than 5 minutes outside the Bluetooth transmission range, the
connection breaks down completely and you have to manually re-establish the
connection. To re-establish a connection to the mobile phone or/and Bluetooth
dongle:
X Briefly press the multi-function button.
Once the connection is successfully re-established, one of the following voice
prompts is announced in the headset:
– “Phone one connected” for the first mobile phone
– “Phone two connected” for the second mobile phone or
– “Dongle connected” for the Bluetooth dongle.
