The Bluetooth device is placed within 1 m (3 feet) of the headset.
The M4U 9 is charged sufficiently.
To pair your device

2 Open the Bluetooth settings on the source device.
3 Switch the M4U 9 to a Listening mode (ANC or ON). The Bluetooth pairing LED will alternately flash
RED and BLUE.
4 Select your M4U 9 headphones from the source device list.
5 Once the M4U 9's link has been established with the source device, the Bluetooth pairing LED will turn
solid BLUE.
6 If pairing fails, the pairing LED will turn solid RED.
To unpair your device
1 Press the Bluetooth Pairing button twice to disconnect currently paired device.
