Using the Auto Call function
If you take the paired earbuds out of the charging case during an
incoming call, the call is automatically accepted and you can use the
earbuds directly for making calls.
You can activate (default setting) or deactivate the function via the
Smart Control app.

When the earphones are connected to your Bluetooth device, the
battery charge status can be displayed on the screen of your smart-
phone or device (depending on the device and operating system
used).
The Smart Control app also displays the charge status of the ear-
buds' rechargeable batteries.
