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.
Using the headset with a PC and a Bluetooth USB dongle
To use the headset with a softphone, you either require a PC supporting Blue-
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:
X Plug the Bluetooth USB dongle into the USB port of your PC.
X Follow the instructions in the next chapter, as well as those given in the in-
struction manual of your Bluetooth USB dongle.
