Both magnets must be aligned with their respective indicationlines for the Edge to receive data.1 Place the GSC 10 on the rear chain stay (on the sideopposite the drive train).2 If necessary, place the flat rubber pad À or the triangle-shaped rubber pad between the GSC 10 and the chain stayfor stability.3 Loosely attach the GSC 10 using two cable ties Á.4 Attach the pedal magnet  to the crank arm using theadhesive mount and a cable tie Ã.The pedal magnet must be within 5 mm of the GSC 10. Theindication line Ä on the pedal magnet must line up with theindication line Å on the GSC 10.5 Unscrew the spoke magnet Æ from the plastic piece.6 Place the spoke in the groove of the plastic piece, andtighten it slightly.The spoke magnet can face away from the GSC 10 if there isnot enough room between the sensor arm and the spoke.The spoke magnet must line up with the indication line Ç onthe sensor arm.7 Loosen the screw È on the sensor arm.8 Move the sensor arm to within 5 mm of the spoke magnet.You can also tilt the GSC 10 closer to either magnet toimprove alignment.9 Select Reset É on the GSC 10.The LED turns red, then green.10Pedal to test the sensor alignment.The red LED blinks each time the pedal magnet passes thesensor. The green LED blinks each time the spoke magnetpasses the sensor arm.NOTE: The LED blinks for the first 60 passes after a reset.Select Reset again if you require additional passes.11When everything is aligned and working correctly, tighten thecable ties, the sensor arm, and the spoke magnet.Garmin recommends that the torque is 1.9 to 2.4 lbf-in. (0.21to 0.27 N-m) to ensure a water tight seal on the GSC 10sensor arm.About the GSC 10Cadence data from the GSC 10 is always recorded. If there isno GSC 10 paired, GPS data is used to calculate the speed anddistance.Cadence is your rate of pedaling or “spinning” measured by thenumber of revolutions of the crank arm per minute (rpm). Thereare two sensors on the GSC 10: one for cadence and one forspeed.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 is to exclude zero values that occur when you arenot pedaling.To change this setting, see page 8.Training with Power Meters• Go to www.garmin.com/intosports for a list of third-partyANT+ sensors that are compatible with your device.• For more information, see the owner's manual for your powermeter.• Adjust your power zones to match your goals and abilities(page 6).• Use range alerts to be notified when you reach a specifiedpower zone (page 3).• Customize the power data fields (page 9).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 From the home screen, select > Training Zones >Power.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, it must be properlyinstalled, paired with your GPS device, and actively recordingdata.For calibration instructions specific to your power meter, refer tothe manufacturer's instructions.1 From the home screen, select .2 Select Bike Profiles.3 Select a profile.4 Select > Calibrate.5 Keep your power meter active by pedaling until the messageappears.6 ANT+ Sensors
