Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible in the Bluetooth
transmission range of your smartphone. The transmission range lar-
gely depends on environmental conditions such as wall thickness,
wall composition etc. With a free line of sight, the transmission
range of most smartphones and Bluetooth devices is up to 10 meters.
If you, and therefore the headphones, leave the Bluetooth transmis-
sion range of the smartphone, the sound quality deteriorates increa-
singly until you hear the voice prompt “Lost connection” and the
connection breaks down completely. If you immediately re-enter the
Bluetooth transmission range, the connection is automatically re-
established.
Deleting the Bluetooth pairing list of the headphones
1. Switch the headphones on (> 13).
2. Press and hold the multi-function button for 3 seconds.
The headphones are in Bluetooth pairing mode. The LED flashes
blue and red.
3. Press and hold the volume
+ button for approx. 3 seconds.
The Bluetooth pairing list is deleted. You hear the voice prompt
“Pairing list cleared”. The LED flashes blue and red 3x. The head-
phones then stay in Bluetooth pairing mode.
