How to Enter Bluetooth Pairing Mode
Slide the power switch towards the Bluetooth icon, and hold it there for about 3 seconds until the LED indicator alternates between flashing RED & BLUE.
Note: If you are turning on the headphones for the first time, the headphones will automatically go into pairing mode (the LED will flash RED & BLUE.)
Now you should be able to find Audition Procast in your device's Bluetooth menu.
