Heart Rate Alerts
Note: Heart rate alerts are a feature
of the Forerunner 305 only.
The heart rate alert notifies you if
your heart rate exceeds or drops
below a specific number of beats
per minute (bpm).
Heart rate alerts can also notify
you if your heart rate exceeds
or drops below a certain heart
rate zone—a range of beats
per minute. The five commonly
accepted heart rate zones can
help you determine the intensity
of your workout. For more
information, or to set your heart
rate zones, see page 51.
To set a heart rate alert:
1. Press mode to access the
Main Menu. Then select
Training.
2. Select Training Options >
Alerts > HR Alert.
3. In the Min HR Alert field,
select a zone from the menu
or select Custom to specify
your own alert value.
4. Repeat for the Max HR Alert.
The maximum value allowed
is 235 bpm.
Note: When enterng custom
heart rate values, you must set your
mnmum and maxmum alerts at
least five bpm apart.
