What do the colours indicate on the LED?

LED Status Lights

Flashing green, yellow and red: Monitor self-test
Flashing green: Operation mode
Flashing yellow: Attention! Connect to the Corentium Pro app for instructions. Often the yellow light means that the time on Corentium Pro needs to be synchronized. Simply start a measurement from the app to set the time. If this does not work, please try installing a new set of batteries.
Blue flash and beep: Bluetooth connect
Blue flash (once): Bluetooth disconnect
Continuous blue: USB connected
Flashing red: The batteries are low, or there is an error. Connect to the Corentium Pro app for instructions. If it still blinks red after replacing the batteries, try starting a new test. If you are unsuccessful after these attempts, please contact support@airthings.com
