Pairing the headset with Bluetooth devices
!
CAUTION
Danger of malfunction!
The transmitted radio waves of mobile phones can impair the operation of sensitive and unprotected devices.
Only make calls with the headset in locations where wireless Bluetooth transmission 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.
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.
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.
To use the headset with a softphone, you either require a
computer supporting Bluetooth or an additional Bluetooth
USB dongle (wireless audio transmitter and receiver).
The BTD 800 USB Bluetooth USB dongle is supplied
together with the Presence Grey UC variants.
