WORKOUT DATA
To reset the Stopwatch and clear workout data, press and hold the

USING THE FITNESS INDEX RECORDING
This feature is used to monitor your fitness efficiency level by moni-
toring how quickly your heart rate starts to come back down after
your workout. As your cardiovascular system improves it will take
less and less time for you heart rate to come back down to a resting
level after your workouts.
This measurement is automatically activated at the end of your
workout when you press the STOP button. To use it correctly, it’s
best to activate it immediately as soon as you have completed your
exercise (or as soon as you finish your cool-down).
When you stop the stopwatch, the display will automatically switch
to the Fitness Index Mode and begin a 60 sec, countdown timer.
During this countdown you should be concentrating on bringing
your body down to a comfortable rest, by taking deep slow breaths
and relaxing your muscles. When the countdown timer reaches
zero, the watch will beep twice and display a number between 0
and 99. The higher this number, the better your recovery rate. Note:
The transmitter belt needs to remain attached to your chest for this
feature to work.
