How does Firstbeat Center recognize my Bodyguard 2 device?

Answer:

In the Firstbeat Center distribution service each Bodyguard 2 device is assigned to individuals based on the devices' serial numbers and individual order IDs. Each device has a unique serial number printed to the device's tag and also coded to the device firmware, and each order placed to the Firstbeat Center has a unique order ID. The devices are prepared for measurements with the Center device tool, and linked to individuals' order IDs.

When the device is returned to the Firstbeat Center, the Device tool recognizes the serial number and sends the measurement data to the correct person based on the order ID.
