To Manually Determine a Recovery Heart Rate
While running the chronograph, the recovery heart rate timer will begin
automatically after pressing STOP/SET/RESET if the Watch is receiving data
from the Digital Heart Rate Sensor.You can also manually initiate a
recovery heart rate after stopping the chronograph by following these
steps.
1. Press MODE until RECOVER appears.
NOTE: From this display, you set the duration of the automatic
recovery heart rate recorded at the end of a chronograph session.
2. Press STOP/SET/RESET to toggle between a 1- or a 2-minute recovery
time.
3. Press START/SPLIT.The top line of the Watch display will show the
heart rate at the beginning of the recovery period followed by your
current heart rate. The bottom line will show the time remaining in
your recovery countdown.
NOTE: The Watch cannot record a recovery unless it is receiving by
valid heart rate data from the Digital Heart Rate Sensor. Without a
current heart rate, the display will read NO HRM DATA at the end of the
recovery period. If the starting heart rate is lower than the ending heart
rate, the display will read NO REC.
4. After a 1- or 2-minute countdown, the Watch will beep indicating the
end of the recovery period. The Watch will capture your heart rate a
second time, subtract the second value from the first value and display
the difference as the recovery.
