Troubleshooting
Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible within the Bluetooth transmission range of your smartphone. The transmission range largely 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 25 meters.
If the headset leaves the Bluetooth transmission range of the smartphone, the sound quality deteriorates until you hear the voice prompt “lost connection... phone x disconnected”. At this point, the connection breaks down completely. If you immediately return to the Bluetooth transmission range, the connection is automatically re-established and you hear the voice prompt ”connected”.
Resetting the headset
If the headset is not functioning properly, reset the headset.
1. Switch the headset off. See page
2. Press the Sound Effect Mode button for 4 seconds.
You can restore the headset to its factory default settings using CapTune.
