    1. Capture the exact failure state

      Reversible

      Check the accessory's own charge/power indicator and whether it appears in the host's Bluetooth or console device list at all. Expected behavior: record eligible measurements through clean skin contact under supported conditions.

    2. Isolate the component boundary

      Reversible

      Clean/dry the back, wear snugly and compare a supported resting measurement. Pair the accessory to a second, different host device to see whether the fault follows the accessory or the original host. Boundary to separate: fit/skin and feature eligibility versus permission, motion and sensor hardware.

    3. Correct only the proven cause

      Reversible

      Correct fit/permissions, update or service persistent sensor failure. Re-pair the accessory, charge it fully, or update the host's Bluetooth/console firmware.

    4. Verify and stop safely

      Reversible

      Confirm the accessory works with the original host after a restart of both devices. Seek medical care for symptoms regardless of wearable readings.
