You should wear the heart rate monitor directly on your skin, just 

below your sternum. It should be snug enough to stay in place 

during your activity.

À

 onto the strap.

Bring the device within 3 m (10 ft.) of the heart rate monitor.

After you put on the heart rate monitor, it is active and sending 

data.
TIP: If the heart rate data is erratic or does not appear, see the 

troubleshooting tips (

).

You can use your Garmin device paired with the heart rate 

monitor to display how much time remains before you are fully 

recovered and ready for the next hard workout. The recovery 

advisor feature includes recovery time and recovery check. 

Recovery advisor technology is provided and supported by 

Firstbeat.

Recovery check: The recovery check provides a real-time 

indication of your state of recovery within the first several 

minutes of an activity.

Recovery time: The recovery time appears immediately 

following an activity. The time counts down until it is optimal 

for you to attempt another hard workout.

Before you can use the recovery advisor feature, you must put 

on the heart rate monitor, and pair it with your device (

). If your device was packaged 

with a heart rate monitor, the device and sensor are already 

paired. For the most accurate estimate, complete the user 

profile setup (

), and set 

your maximum heart rate (

).

Select Menu > My Stats > Recovery Advisor > Enable.

Go for a ride.
Within the first several minutes of your ride, a recovery check 

appears, showing your real-time state of recovery.

After your ride, select Save Ride.
The recovery time appears. The maximum time is 4 days, 

and the minimum time is 6 hours.

VO2 max. is the maximum volume of oxygen (in milliliters) you 

can consume per minute per kilogram of body weight at your 

maximum performance. In simple terms, VO2 max. is an 

indication of athletic performance and should increase as your 

level of fitness improves. VO2 max. estimates are provided and 

supported by Firstbeat. You can use your Garmin device paired 

with a compatible heart rate monitor and power meter to display 

your cycling VO2 max. estimate.

Before you can view your VO2 max. estimate, you must put on 

the heart rate monitor, install the power meter, and pair them 

with your device (

). If 

your device was packaged with a heart rate monitor, the device 

and sensor are already paired. For the most accurate estimate, 

complete the user profile setup (

), and set your maximum heart rate (

).

NOTE: The estimate may seem inaccurate at first. The device 

requires a few rides to learn about your cycling performance.

Ride at a steady, high intensity for at least 20 minutes 

outdoors.

After your ride, select Save Ride.

Select Menu > My Stats > VO2 Max..
Your VO2 max. estimate appears as a number and position 

on the color gauge.
