Pressing any key other than

Adjust your target heart rate at any time during your
workout by pressing 
, using the 
keys as
needed, and pressing 
again. If you are lowering your target, you are limited to a 5 bpm change.
The time and distance accumulated during warmup are not counted against your selected workout time or distance; those values start at zero when the treadmill reaches heart rate control mode. This time and distance are accumulated into the workout summary data, as is your cooldown exercise.
Interval HRC works just like constant heart rate control up through the first work interval.
When your workout reaches your first rest interval, your workload is reduced by half, and kept at this rate throughout the rest interval.
The next work interval is initially set at an average of the workloads in the previous work interval.
