4 Wrap the strap 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. Tips for Erratic Heart Rate Data If the heart rate data is erratic or does not appear, you can try these tips. • Reapply water to the electrodes and contact patches (if applicable). • Tighten the strap on your chest. • Warm up for 5 to 10 minutes. • Follow the care instructions (Caring for the Heart Rate Monitor, page 13). • Wear a cotton shirt or thoroughly wet both sides of the strap. Synthetic fabrics that rub or flap against the heart rate monitor can create static electricity that interferes with heart rate signals. • Move away from sources that can interfere with your heart rate monitor. Sources of interference may include strong electromagnetic fields, some 2.4 GHz wireless sensors, high-voltage power lines, electric motors, ovens, microwave ovens, 2.4 GHz cordless phones, and wireless LAN access points. Fitness Goals Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying these principles. • Your heart rate is a good measure of exercise intensity. • Training in certain heart rate zones can help you improve cardiovascular capacity and strength. If you know your maximum heart rate, you can use the table (Heart Rate Zone Calculations, page 16) to determine the best heart rate zone for your fitness objectives. If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms and health centers can provide a test that measures maximum heart rate. The default maximum heart rate is 220 minus your age. Installing the Speed Sensor NOTE: If you do not have this sensor, you can skip this task. TIP: Garmin recommends you secure your bike on a stand while installing the sensor. 1 Place and hold the speed sensor on top of the wheel hub. 2 Pull the strap around the wheel hub, and attach it to the hook on the sensor. The sensor may be tilted when installed on an asymmetrical hub. This does not affect operation. 3 Rotate the wheel to check for clearance. The sensor should not contact other parts of your bike. NOTE: The LED flashes green for five seconds to indicate activity after two revolutions. Installing the Cadence Sensor NOTE: If you do not have this sensor, you can skip this task. TIP: Garmin recommends you secure your bike on a stand while installing the sensor. 1 Select the band size that fits your crank arm securely. The band you select should be the smallest one that stretches across the crank arm. 2 On the non-drive side, place and hold the flat side of the cadence sensor on the inside of the crank arm. 3 Pull the bands around the crank arm, and attach them to the hooks on the sensor. 4 Rotate the crank arm to check for clearance. The sensor and bands should not contact any part of your bike or shoe. NOTE: The LED flashes green for five seconds to indicate activity after two revolutions. 5 Take a 15 minute test ride and inspect the sensor and bands to ensure there is no evidence of damage. About the Speed and Cadence Sensors Cadence data from the cadence sensor is always recorded. If no speed and cadence sensors are paired with the device, GPS data is used to calculate the speed and distance. Cadence is your rate of pedaling or "spinning" measured by the number of revolutions of the crank arm per minute (rpm). Pairing Your Wireless Sensors Before you can pair, you must put on the heart rate monitor or install the sensor. Pairing is the connecting of ANT+ or Bluetooth wireless sensors. For example, connecting a heart rate monitor with your Garmin device. 1 Bring the device within 3 m (10 ft.) of the sensor. NOTE: Stay 10 m (33 ft.) away from other riders' sensors while pairing. 2 Hold . 3 Select Sensors > Add Sensor. A list of available sensors appears. 4 Select one or more sensors to pair with your device. When the sensor is paired with your device, the sensor status is Connected. You can customize a data field to display sensor data. Wireless Sensors 9
