The watch uses a standard watch battery. When the display dims or functions become erratic, it may be time to replace the battery. It is recommended to have the battery replaced by a qualified watch technician to ensure the water resistance seal is maintained.

• Inaccurate Heart Rate Readings: Ensure the watch is worn snugly on your wrist, not too loose or too tight. Clean the optical sensor on the back of the watch. Avoid excessive movement during measurement.
• Inaccurate Pedometer Readings: Ensure your user profile (height, weight) is correctly set up. Arm movements can sometimes affect step counting; try to keep your arm relatively still during walking for best accuracy.
• Water Resistance Concerns: Always ensure the watch's back cover is securely fastened after any maintenance. Avoid pressing buttons underwater.
