During the startup phase, the display shows up to 4 flashing dashes indicating the time left until radon levels are shown.
In this phase, your Corentium Home is functioning and gathering data on the indoor environment. Depending on the indoor radon levels, this startup phase typically ranges between 6 and 24 hours.
Once the monitor has collected enough data, it will start displaying the radon levels in your room.
Here at Airthings, we suggest you let your Corentium Home monitor your indoor air quality as long as possible.
