Getting Started
Charging the headsets
Insert the headsets into the charging case slots. Close the charging case. By
closing the charging case, the headsets get contact and are automatically
charged in the case.
Charging the case
Connect the charging cable that came with the case to the Type-C® charging
input of the case and a travel charger or USB port of a computer to charge the
built-in battery. The charging status indicator flashes red during charging,
changes to white when fully charged and goes out after a few seconds.

Open the case cover and both headset units switch on automatically. Put the
headsets into the charging case and close it, the headsets turn off
automatically.

Tap and hold the multifunction sensor for 6 seconds, the headset will turn
off.
Note:

Pairing
The Cero headset must be paired with a Bluetooth® enabled device to be used.
- Opening the case cover switches both headset units on automatically. They synchronize with each other and one of the two headsets goes into pairing mode to connect to a Bluetooth® source.
- Search for „Cero“ on your Bluetooth® enabled device and select it from the list of found devices to pair the headset with the Bluetooth device.
Note:
-
If the case is closed with the headsets inserted, the connection is interrupted. As soon as the case is opened, they automatically reconnect.
If the headset units do not connect automatically or an existing connection is disconnected, switch both headsets off and on again either by inserting and removing them from the charging case, or manually. -
If the headset does not find a Bluetooth®-enabled device, it switches off after approx. 2 minutes.
