Trouble shooting
1. The headset is not working
Please check the battery: it could be low, please charge it for 3 hours.
2. There is no sound coming out of the headset
Please check whether the speakers and microphone were connected right. Also check
the volume: maybe you have set it too low?
3. Whistling of the speakers
If the microphone is too close to the speaker, the speaker could produce a ‘whistling’
sound. Enlarge the distance between the microphone and the speaker and the problem
should be solved.
4. Lose connection with the mobile phone or music device
Please check the battery: if it is too low, the Blue Biker could lose the connection with
the mobile phone.
5. Cannot reconnect with your mobile phone
Please consult the list of previously paired devices on your mobile phone: remove all
the names on the list, then turn off the headset, and remove your mobile phone’s battery
for a few seconds. Replace the battery, turn on your mobile phone and let your phone
search for Bluetooth
®
devices again. Now you can reconnect with the Blue Biker.
