If the LED is not coming on at all when pressing a button on the remote:
1. Plug in to USB charger, wait a few seconds, and try again
2. If still not working, and the LED is NOT blinking blue after pressing a button, try resetting the remote by pressing the pinhole button on the bottom, next to the USB charger.
If the remote LED is flashing blue when a button is pressed:
1. Press and hold the Caavo and Back buttons together on the remote until the LED flashes green and red. This will put the remote in to pairing mode.
2. Press and hold the + and - buttons on the Caavo top panel until you see the remote pairing screen appear on the Caavo UI and follow the on-screen instructions.
