Firstly check the CR2032 battery is properly inserted in the remote unit.
Press and hold the play/pause and green buttons then press the red button several times.
This has to be done when you see the Parrot logo on the display screen.
Within 1 to 2 seconds, you should then see a 'Pairing Remote Control' message displayed on the screen. At that time, you can release the buttons and the remote should then be paired with the kit and the message will go away. You can verify remote operation by navigating through the menus.
If you are unsuccessful on the 1st attempt, power off the unit until you see the 'Goodbye'message, power it back on, and repeat the process.
