Initializing the neckband speaker
If the neckband speaker fails to operate successfully after you reset it, initialize the neckband speaker to resume its factory default settings.
Make sure the neckband speaker is turned off, and then press the 
(power)/
(BLUETOOTH) button and the 
(play/call) button on the neckband speaker simultaneously for about 7 seconds.
Note
-
While charging is in progress, you cannot initialize the neckband speaker.
Upon completion of initialization, the indicator on the neckband speaker flashes 4 times in blue.
The settings, such as the volume settings, are restored to the factory default settings and all the pairing information is deleted.
