Replace the Battery: Gently release the old CR2032 battery from its housing. Note the orientation of the battery (positive side up) before removing it. Install the new CR2032 battery, ensuring the correct side (positive side) is facing upwards. Minimize touching the flat surfaces of the new battery with your fingers; handling it by the edges is recommended to avoid transferring oils.
