Broadcasting Heart Rate Data You can broadcast your heart rate data from your watch and view it on paired devices. Broadcasting heart rate data decreases battery life.

NOTE: You can add options to the controls menu (Customizing the Controls Menu, page 31). 2 Press START. The watch starts broadcasting your heart rate data. 3 Pair your watch with your compatible device. NOTE: The pairing instructions differ for each Garmin compatible device. See your owner's manual. 4 Press STOP to stop broadcasting your heart rate data. Pulse Oximeter Your watch has a wrist-based pulse oximeter to gauge the peripheral saturation of oxygen in your blood (SpO2). As your altitude increases, the level of oxygen in your blood can decrease. You can manually begin a pulse oximeter reading by viewing the pulse oximeter glance (Getting Pulse Oximeter Readings, page 51). You can also turn on all-day readings (Turning On All-Day Mode, page 51). When you view the pulse oximeter glance while you are not moving, your watch analyzes your oxygen saturation and your elevation. The elevation profile helps indicate how your pulse oximeter readings are changing, relative to your to elevation. On the watch, your pulse oximeter reading appears as an oxygen saturation percentage and color on the graph. On your Garmin Connect account, you can view additional details about your pulse oximeter readings, including trends over multiple days.
