Garmin A03001 Owner's Manual

centers can provide a test that measures maximum heart rate.The default maximum heart rate is 220 minus your age.Tips for Erratic Heart Rate DataIf the heart rate data is erratic or does not appear, you can trythese tips.• Reapply water to the electrodes and contact patches.• Tighten the strap on your chest.• Warm up for 5–10 minutes.• Follow the care instructions (Caring for the Heart RateMonitor, page 19).• Wear a cotton shirt or thoroughly wet both sides of the strap.Synthetic fabrics that rub or flap against the heart ratemonitor can create static electricity that interferes with heartrate signals.• Move away from sources that can interfere with your heartrate monitor.Sources of interference may include strong electromagneticfields, some 2.4 GHz wireless sensors, high-voltage powerlines, electric motors, ovens, microwave ovens, 2.4 GHzcordless phones, and wireless LAN access points.Installing the Speed SensorNOTE: If you do not have this sensor, you can skip this task.TIP: Garmin recommends you secure your bike on a stand whileinstalling the sensor.1 Place and hold the speed sensor on top of the wheel hub.2 Pull the strap À around the wheel hub, and attach it to thehook Á on the sensor.The sensor may be tilted when installed on an asymmetricalhub. 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 indicateactivity after two revolutions.Installing the Cadence SensorNOTE: If you do not have this sensor, you can skip this task.TIP: Garmin recommends you secure your bike on a stand whileinstalling the sensor.1 Select the band size that fits your crank arm À securely.The band you select should be the smallest one thatstretches across the crank arm.2 On the non-drive side, place and hold the flat side of thecadence sensor on the inside of the crank arm.3 Pull the bands Á around the crank arm, and attach them tothe hooks Â on the sensor.4 Rotate the crank arm to check for clearance.The sensor and bands should not contact any part of yourbike or shoe.NOTE: The LED flashes green for five seconds to indicateactivity after two revolutions.5 Take a 15 minute test ride and inspect the sensor and bandsto ensure there is no evidence of damage.About the Speed and Cadence SensorsCadence data from the cadence sensor is always recorded. If nospeed and cadence sensors are paired with the device, GPSdata is used to calculate the speed and distance.Cadence is your rate of pedaling or “spinning” measured by thenumber of revolutions of the crank arm per minute (rpm).Data Averaging for Cadence or PowerThe non-zero data-averaging setting is available if you aretraining with an optional cadence sensor or power meter. Thedefault setting excludes zero values that occur when you are notpedaling.You can change the value of this setting (Data RecordingSettings, page 18).Pairing Your ANT+ SensorsBefore you can pair, you must put on the heart rate monitor orinstall the sensor.Pairing is the connecting of ANT+ 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' ANT+sensors while pairing.2 Select > Settings > Sensors > Add Sensor.3 Select an option:• Select a sensor type.• Select Search All to search for all nearby sensors.A list of available sensors appears.4 Select one or more sensors to pair with your device.5 Select Add.When the sensor is paired with your device, the sensor statusis Connected. You can customize a data field to displaysensor data.Training with Power Meters• Go to www.garmin.com/intosports for a list of ANT+ sensorsthat are compatible with your device (such as Vector™).• For more information, see the owner's manual for your powermeter.• Adjust your power zones to match your goals and abilities(Setting Your Power Zones, page 13).• Use range alerts to be notified when you reach a specifiedpower zone (Setting Range Alerts, page 16).• Customize the power data fields (Customizing the DataScreens, page 16).12 ANT+ Sensors
