MANUAL: Instead of determining your target heart rate zone by using OwnZone or Automatic limits, you can determine
your target heart rate limits manually by using the age formula.
Your target heart rate zone is a range between lower and upper heart rate limits expressed as percentages of
your maximum heart rate (HR
max
) or as beats per minute (bpm). HR
max
is the highest number of heartbeats per
minute during maximum physical exertion. The wrist unit calculates your HR
max
according to your age:
Maximum heart rate = 220–age. For more accurate measurement of your HR
max
, visit your doctor or exercise
physiologist for an exercise stress test.
The wrist unit displays your previously determined heart rate limits. Alternatively, if you have not determined
the manual limits before your age-based limits are displayed.
Press the / buttons to set the upper limit. Press OK.
Press the / buttons to set the lower limit. Press OK.
OFF: The function is switched off and there are no target heart rate limits during the exercise session.
