A. 1. Ensure proper fit: Make sure the device is snug on your wrist, as a loose fit can lead to inaccurate readings. 2. Clean the sensor: Wipe the heart rate sensor on the back of the device with a soft cloth to remove any dirt or sweat that may interfere with readings.

B. 3. Avoid wearing the device over clothing: For the most accurate readings, wear the device directly against your skin. 4. Calibrate the heart rate settings: Check the app settings for any calibration options that may improve accuracy.
