Sensors and Accessories The D2 Mach 1 watch has several internal sensors, and you can pair additional wireless sensors for your activities. Wrist Heart Rate Your watch has a wrist-based heart rate monitor, and you can view your heart rate data on the heart rate glance (Viewing the Glance Loop, page 40). The watch is also compatible with chest heart rate monitors. If both wrist-based heart rate and chest heart rate data are available when you start an activity, your watch uses the chest heart rate data. Wearing the Watch CAUTION Some users may experience skin irritation after prolonged use of the watch, especially if the user has sensitive skin or allergies. If you notice any skin irritation, remove the watch and give your skin time to heal. To help prevent skin irritation, ensure the watch is clean and dry, and do not overtighten the watch on your wrist. For more information, go to garmin.com/fitandcare. • Wear the watch above your wrist bone. NOTE: The watch should be snug but comfortable. For more accurate heart rate readings, the watch should not shift while running or exercising. For pulse oximeter readings, you should remain motionless. NOTE: The optical sensor is located on the back of the watch. • See Tips for Erratic Heart Rate Data, page 53 for more information about wrist-based heart rate. • See Tips for Erratic Pulse Oximeter Data, page 54 for more information about the pulse oximeter sensor. • For more information about accuracy, go to garmin.com/ataccuracy. • For more information about watch wear and care, go to garmin.com/fitandcare. Tips for Erratic Heart Rate Data If the heart rate data is erratic or does not appear, you can try these tips. • Clean and dry your arm before putting on the watch. • Avoid wearing sunscreen, lotion, and insect repellent under the watch. • Avoid scratching the heart rate sensor on the back of the watch. • Wear the watch above your wrist bone. The watch should be snug but comfortable. • Wait until the icon is solid before starting your activity. • Warm up for 5 to 10 minutes and get a heart rate reading before starting your activity. NOTE: In cold environments, warm up indoors. • Rinse the watch with fresh water after each workout. • While exercising, use a silicone band. Wrist Heart Rate Monitor Settings Hold MENU, and select Sensors & Accessories > Wrist Heart Rate. Status: Enables or disables the wrist heart rate monitor. The default value is Auto, which automatically uses the wrist heart rate monitor unless you pair an external heart rate monitor. NOTE: Disabling the wrist heart rate monitor also disables the wrist-based pulse oximeter sensor. You can perform a manual reading from the pulse oximeter glance. While Swimming: Enables or disables the wrist heart rate monitor during swimming activities. Abnormal Heart Rate Alerts: Allows you to set the watch to alert you when your heart rate exceeds or drops below a target value (Setting an Abnormal Heart Rate Alert, page 53). Broadcast Heart Rate: Allows you to begin broadcasting your heart rate data to a paired device (Broadcasting Heart Rate Data, page 53). Setting an Abnormal Heart Rate Alert CAUTION This feature only alerts you when your heart rate exceeds or drops below a certain number of beats per minute, as selected by the user, after a period of inactivity. This feature does not notify you of any potential heart condition and is not intended to treat or diagnose any medical condition or disease. Always defer to your health care provider for any heart-related issues. You can set the heart rate threshold value. 1 Hold MENU. 2 Select Sensors & Accessories > Wrist Heart Rate > Abnormal Heart Rate Alerts. 3 Select High Alert or Low Alert. 4 Set the heart rate threshold value. Each time your heart rate exceeds or drops below the threshold value, a message appears and the watch vibrates. 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. TIP: You can customize the activity settings to broadcast your heart rate data automatically when you begin an activity (Activities and App Settings, page 24). For Sensors and Accessories 53
