How can I connect external devices, such as a heart-rate monitor?
Go to Settings (see FAQ How can I access the settings of my on-board computer?) and activate Bluetooth. An automatic search takes place for heart rate monitors within range. Select the required heart rate monitor to connect with it. The active connection to the heart rate monitor can be recognised by the white heart symbol in the Status screen. If you have activated a Bluetooth-enabled heart rate monitor, the heart rate will be displayed on a screen.
