Getting started

Pairing the headphones with a Bluetooth device

Ensure that the headphones are within the 20 cm range of your smartphone

when performing this procedure.

1. Switch the headphones on (see page 19).

– If you pair the headphones to the device for the first time, they automatically

go to pairing mode.

– If the headphones don’t automatically go to pairing mode, switch the

headphones off and press the power button again for 4 seconds or until

you hear the voice prompt “power on” and a beep sound.

The LED flashes blue and red. The headphones are in pairing mode.

2. Activate Bluetooth on your smartphone.

3. On your smartphone, start a search for Bluetooth devices.

All active Bluetooth devices in the proximity of your smartphone are

displayed.

4. From the list of found Bluetooth devices, select “HD 4.50BTNC”. If necessary,

enter the default PIN code “0000”.

If pairing was successful, you hear the voice prompt “connected”. The LED

flashes blue 3 times.
