The heart rate monitor comes with three extender straps to fit different chest sizes. TIP: The medium strap extender works for most shirt sizes (from medium to extra-large). • Put on the heart rate monitor backward to easily adjust the slider on the strap extender. • Put on the heart rate monitor forward to easily adjust the slider on the heart rate monitor. Putting On the Heart Rate Monitor You should wear the heart rate monitor directly on your skin, just below your sternum. 1 Select a strap extender for the best fit. 2 Wear the heart rate monitor with the Garmin logo facing right- side up. The hook and loop connection should be on your right side. 3 Wrap the heart rate monitor around your chest, and connect the strap hook to the loop. Caring for the Heart Rate Monitor NOTICE A buildup of sweat and salt on the strap can decrease the ability of the heart rate monitor to report accurate data. • Rinse the heart rate monitor after every use. • Hand wash the heart rate monitor after every seven uses, using a tiny amount of mild detergent, such as dishwashing liquid. NOTE: Using too much detergent may damage the heart rate monitor. • Do not put the heart rate monitor in a washing machine or dryer. • When drying the heart rate monitor, hang it up or lay it flat. HRM-Tri Accessory The HRM-Swim section of this manual explains recording heart rate during your swim (Heart Rate While Swimming, page 11). Pool Swimming NOTICE Hand wash the heart rate monitor after exposure to chlorine or other pool chemicals. Prolonged exposure to these substances can damage the heart rate monitor. The HRM-Tri accessory is designed primarily for open water swimming, but it can be used occasionally for pool swimming. The heart rate monitor should be worn under a swim suit or triathlon top during pool swimming. Otherwise, it may slide down your chest when pushing off the pool wall. Putting On the Heart Rate Monitor You should wear the heart rate monitor directly on your skin, just below your sternum. It should be snug enough to stay in place during your activity. 1 If necessary, attach the strap extender to the heart rate monitor. 2 Wet the electrodes on the back of the heart rate monitor to create a strong connection between your chest and the transmitter. 3 Wear the heart rate monitor with the Garmin logo facing rightside up. NOTE: Make sure the care tag does not fold over. 4 Tighten the heart rate monitor so it is snug around your chest, but not restrictive. After you put on the heart rate monitor, it is active, storing, and sending data. Tips for Using the HRM-Swim Accessory • Adjust the tightness of the heart rate monitor and strap extender if the heart rate monitor slides down your chest when pushing off the pool wall. • Stand up between intervals so that the heart rate monitor is out of the water to see your heart rate data. The loop and hook connection should be on your right side. 4 Wrap the heart rate monitor around your chest, and connect the strap hook to the loop. NOTE: Make sure the care tag does not fold over. After you put on the heart rate monitor, it is active and sending data. 12 Heart Rate Features
