Garmin Edge® 520 Bundle Owner's Manual

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.

Take a 15 minute test ride and inspect the sensor and bands 

to ensure there is no evidence of damage.

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).

The non-zero data-averaging setting is available if you are 

training with an optional cadence sensor or power meter. The 

default setting excludes zero values that occur when you are not 

pedaling.
You can change the value of this setting (

).

Before you can pair, you must put on the heart rate monitor or 

install the sensor.
Pairing is the connecting of ANT+ wireless sensors, for example, 

connecting a heart rate monitor with your Garmin device.

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.

Select Menu > Settings > Sensors > Add Sensor.

Select an option:
• Select a sensor type.
• Select Search All to search for all nearby sensors.
A list of available sensors appears.

Select one or more sensors to pair with your device.

Select Add Sensor.
When the sensor is paired with your device, the sensor status 

is Connected. You can customize a data field to display 

sensor data.

• Go to 

 for a list of ANT+ sensors 

that are compatible with your device (such as Vector

™

).

• For more information, see the owner's manual for your power 

meter.

• Adjust your power zones to match your goals and abilities 

).

• Use range alerts to be notified when you reach a specified 

power zone (

).

• Customize the power data fields (

).

The values for the zones are default values and may not match 

your personal abilities. You can manually adjust your zones on 

the device or using Garmin Connect. If you know your functional 

threshold power (FTP) value, you can enter it and allow the 

software to calculate your power zones automatically.

Select Menu > My Stats > Training Zones > Power Zones.

Enter your FTP value.

Select Based On:.

Select an option:
• Select watts to view and edit the zones in watts.
• Select % FTP to view and edit the zones as a percentage 

of your functional threshold power.

Before 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 the 

manufacturer's instructions.

Select Menu > Training > Sensors.

Select your power meter.

Select Calibrate.

Keep your power meter active by pedaling until the message 

appears.

Follow the on-screen instructions.

Vector measures pedal-based power.
Vector measures the force you apply a few hundred times every 

second. Vector also measures your cadence or rotational 

pedaling speed. By measuring the force, the direction of force, 

the rotation of the crank arm, and time, Vector can determine 

power (watts). Because Vector independently measures left and 

right leg power, it reports your left-right power balance.
NOTE: The Vector S system does not provide left-right power 

balance.

Cycling dynamics metrics measure how you apply power 

throughout the pedal stroke, and where you apply power on the 

pedal, allowing you to understand your particular way of riding. 

Understanding how and where you produce power allows you to 

train more efficiently and evaluate your bike fit.

Before you can use cycling dynamics, you must pair the Vector 

power meter with your device (

).

NOTE: Recording cycling dynamics uses additional device 

memory.
