Switching the device by one touch (NFC)
When the headset is connected with a Bluetooth device, if you touch an NFC -compatible smartphone on the
headset, the headset is connected with the smartphone that was touched on the headset most recently (One-touch
connection switching). However, if you are talking on a Bluetooth mobile phone connected to the headset, you cannot
switch the Bluetooth connection by one touch.
When the headset is connected with an NFC-compatible smartphone, if you touch the smartphone on another NFC-
compatible Bluetooth headset or Bluetooth speaker, the smartphone disconnects from the headset, and connects to
the Bluetooth device it touched.
Note
Unlock the screen of the smartphone if it is locked.
