Initializing the transmitter
When the supplied transmitter is not working properly, initialize the transmitter to resume its factory default settings.
Make sure that the transmitter is connected to a TV or an AC outlet, and then press and hold the(BLUETOOTH) button for about 10 seconds until the indicator flashes 4 times in blue.
The transmitter is initialized and the pairing information of all the BLUETOOTH devices is deleted.
Initializing the transmitter does not delete the pairing information of the neckband speaker.
