the time. If this does not work, please try installing a new set of batteries.

• 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
