The FR70 and FR60 calculate calories based on a heart rate calculation generated by Garmin. This generic heart-rate-rate based calorie count uses the following information to determine calories:
- Heart rate*
- Activity class
The FR60 will need to be at software version 2.40 or higher to use this calorie formula. Use myDashboard to update the software on either of these devices.
*If a heart rate monitor is not being used, the FR70 and FR60 will determine calories based on speed or pace. This will require a Garmin Speed/Cadence Sensor (GSC 10) for cycling or a Garmin Foot Pod for running/walking.
