If you cannot connect your Android smartphone to the headset, delete the headset pairing information on your Android
smartphone and perform pairing again. As for the operations on your Android smartphone, refer to the operating instructions
supplied with the Android smartphone.
If there is no pairing history between the headset and the Bluetooth connected device, even when you try to change the mode on
the headset, it is not possible to switch from the Bluetooth connection to the USB transceiver connection.
