  • Green LED flashing once per second indicates a radon test is scheduled.

  • Yellow LED flashing indicates a warning but is still operational. This usually means that the monitor needs to synchronize the date, time, and time zone. To bring the Pro back to green light status, connect to the app by scheduling a new test.
