Setup and syncing: charge the device, confirm Bluetooth is enabled, use the app named in your product guide, and keep the phone nearby during pairing. If a device was paired directly in phone settings, remove that pairing and retry through the app.
Fit and readings: wear the sensor flat against clean, dry skin. For an air-pump wrist check, place the cuff on bare skin, support the arm, keep the wrist near heart level, and stay still. For R7, confirm the ring size is secure without being tight.
Charging: dry the device and charging contacts, align the charger carefully, and use a standard low-power USB source unless the product guide states otherwise.
