Home: Error Message / Error codes 4, 526, 518, and 522

If your Home radon detector is showing an error message or a specific error code, please try the following:

  1. Put the device in a dry location in room temperature. Keep it there for 24 hours. 

  2. Press the reset button on the back of the device. See if the device now works as intended. 

  3. If step two didn't work, take out the batteries, wait for 30 minutes, reinsert brand new batteries from Duracell or Energizer. 

If this does not solve the problem, your device has a critical issue. Please find your serial number at the back of your detector and contact us here. Tell us that you have already tried the troubleshooting from this article.
