Structure of an interval training exercise:
Exercising with Interval Training Set (Int On, E1-E5)
In this mode you can also use the functions described in “Recording mode”
section.
The Interval Trainer automatically guides you through your exercise. In
order to hear the activity sounds when the phase starts and stops make
sure the activity sound is on. If you have turned the countdown timer of
the phase off, you have to stop the phase manually by pressing and holding
OK button. When the stopwatch starts running indicates that Interval
Trainer is on. As the interval training exercise ends the wrist unit
automatically starts a BasicUse exercise, which is recorded to the same file
as your interval training exercise.
