Using the headphones
14 | ACCENTUM PLUS
If the LED display does not light up:
▷ Clean the charging socket (> 36).
▷ Charge the rechargeable battery until the LED display lights up
again (at least 30 minutes) (> 13). If the rechargeable battery is
completely discharged, it may take several minutes for the LED
display to indicate the charging process.
Connecting the headphones to a
Bluetooth device
To be able to use the Bluetooth connection, you must register both
devices (headphones and e.g. smartphone) once. This process is
called pairing.
If operation differs from the steps mentioned, also refer to the
instruction manual of the Bluetooth device you are using.

list is empty), they automatically switch to pairing mode.
