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 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 around the crank arm, and attach them tothe hooks 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 17).Pairing Your Wireless SensorsBefore you can pair, you must put on the heart rate monitor orinstall the sensor.Pairing is the connecting of ANT+ or Bluetooth wireless sensors,for example, connecting a heart rate monitor with your Garmindevice.1 Bring the device within 3 m (10 ft.) of the sensor.NOTE: Stay 10 m (33 ft.) away from other riders' sensorswhile pairing.2 Select Menu > 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 Sensor.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 12).• 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).Setting Your Power ZonesThe values for the zones are default values and may not matchyour personal abilities. You can manually adjust your zones onthe device or using Garmin Connect. If you know your functionalthreshold power (FTP) value, you can enter it and allow thesoftware to calculate your power zones automatically.1 Select Menu > My Stats > Training Zones > Power Zones.2 Enter your FTP value.3 Select Based On:.4 Select an option:• Select watts to view and edit the zones in watts.• Select % FTP to view and edit the zones as a percentageof your functional threshold power.Calibrating Your Power MeterBefore you can calibrate your power meter, you must install it,pair it with your device, and begin actively recording data with it.For calibration instructions specific to your power meter, see themanufacturer's instructions.1 Select Menu > Settings > Sensors.2 Select your power meter.3 Select Calibrate.4 Keep your power meter active by pedaling until the messageappears.5 Follow the on-screen instructions.12 Wireless Sensors
