On the top left corner of the remote control is a small led that flashes/blinks either blue, red or green.
Green light when a button is pressed - Your remote is working fine.
Blue 3 blinks - Remote was just woken up (moved) and is ready for use.
Blue blinking continuously - Remote is disconnected from the main unit. Either the remote is out of range from main unit or the main unit is switched off. Turn on the main unit or move close to the main unit. If this does not fix the issue, see article Remote is Not Working.
Red blink when pressing any key - Your remote control is low on power.
No LED Indicator - Remote out of charge completely. Please replace the batteries.
Alternate Red and Green Blink - This happens when you are trying to unpair the remote. (Expert tip: To unpair the remote from main unit, press and hold the CAAVO and Back buttons together for 5 seconds).
Continuous green blink - Control Center remote is in pairing mode. Wait till the pairing is completed.
