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. Note that both earbuds must be switched on to
adjust the settings for both earbuds (right and left).
The right or left earbud can be used alone. If you insert one
earbud into the charging case during use, a short interruption
of playback may occur in the other earbud.
Using the Sidetone function
When using the earbuds for phone calls, you may find it more com-
fortable if your own voice is audible in the earbuds. With the
Sidetone function activated, your own voice is played back through
the earbuds during a phone call.
You can activate the function (default setting) and adjust settings or
deactivate the function via the Smart Control app. Note that both
earbuds must be switched on to adjust the settings for both earbuds
(right and left).
Displaying the battery charge status
When the earbuds are connected to your Bluetooth device, the bat-
tery 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.
Displaying the battery charge status using the charging case
If no USB cable is connected to the charging case:
▷
Open the lid of the charging case.
The LED of the charging case displays the battery charge status.
If you close the lid of the charging case, the LED will go off after
5 seconds.
