Troubleshooting
Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible in the Bluetooth transmission
range of your smartphone. The transmission range largely depends on environ-
mental 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 the headphones leave the Bluetooth transmission range of the smartphone,
the sound quality deteriorates and you repeatedly hear the voice prompt “lost
connection”. At this point, the connection breaks down completely. You can
re-establish the connection if you re-enter the Bluetooth transmission range
and you hear the voice prompt ”connected”.
To re-establish the connection:
X Press the 3-way multi-function button.
Clearing the pairing settings
1. Switch the headphones on (see page 17). Press the power button and keep
it pressed until you hear the voice prompt “pairing” and the LED flashes blue
and red.
The headphones are in pairing mode.
2. Simultaneously press the 3-way multi-function button and the power button
for 3 seconds.
The LED flashes 3 times purple and the headphones change to pairing mode.
The pairing settings are cleared from the headphones.
