Hammerhead Heart Rate Monitor - Battery Replacement

Steps to Replace the Heart Rate Monitor Battery:

1. Find the battery door located on the underside of the sensor pod.

2. Insert a coin that fits (examples are: $ quarter, £ 20p or € 20c) into the slot and rotate anti-clockwise.

3. When the battery door becomes loose, remove it carefully. The battery will be inside the battery door when you remove it.

4. Wait for around 20-30 seconds.

5. Insert a new battery into the battery door slot with the positive side (+) of the battery facing up.

6. Ensure the rubber seal on the battery door is in place.

7. Once the new battery is in place, reattach the battery door by placing the door over the markers.

8. Insert the coin used to open the battery door and rotate clockwise until the battery door fits flush with the sensor pod underside.
