  4. Replace the battery with a new one of type CR123A, observing the polarity.

    Never use used or damaged batteries.

  5. Replace the back of the detector.
  6. Turn on the detector and check the battery status in the app.

    The battery status is not updated immediately, but only the next time the hub queries the devices (every 36 seconds by default).
