The Wave 1st gen will start making a sounding an alarm every 5 minutes when the light ring is red and the unit has measured:

above 150 Bq/m3 or 4 pCi/L as an average for more than 3 months
OR
above 200 Bq/m3 or 5.4 pCi/L as an average for more than 1 month.

You can snooze the alarm by simply waving in front of your machine: this will silence the audio alarm for one month.

PLEASE NOTE: the alarm is a feature of Wave 1st gen only
