and lower limit value.

The preset zones are based on the following percentages of your
maximum heart rate (HR
MAX
):
Zone 1 – 50% - 60% HR
MAX
Zone 2 – 60% - 70 % HR

Zone 3 – 70% - 80% HR

Zone 4 – 80% - 90% HR

Zone 5 – 90% - 100% HR

NOTE: If you select a preset zone, the only other option you can
change is the alert type; the limit settings for the preset zones
cannot be changed. If you wish to enter specific target zone
limits, first select MANUAL as the target zone, and then set the
limits as desired.
NOTE: When setting the manual limits, the lower limit is the
value to the left of the separator and the upper limit is to the
right of it. If the limits are set to “nonsense” values (for example,
the lower limit is set higher than the higher limit), the watch will
change them to more logical values when you press DONE.
These corrections may yield unexpected results, so be sure to
double-check your settings when using the MANUAL limits.
