Detecting Performance Measurements Automatically

The Auto Detection feature is turned on by default. The watch can automatically detect your maximum heart rate and lactate threshold during an activity. When paired with a compatible power meter, the watch can automatically detect your functional threshold power (FTP) during an activity.

NOTE: The watch detects a maximum heart rate only when your heart rate is higher than the value set in your user profile (Setting Up Your User Profile).

1. Hold MENU.
2. Select User Profile > Heart Rate & Power Zones > Auto Detection.
3. Select an option.
