HEART RATE LIMITS / ALERT
To manually calculate your own heart rate limits:
MHR
MHR = 220-age
LOWER LIMIT
MHR x lower target activity %.
E.g. Target activity is WALK:
Lower limit = MHR x 65%
UPPER LIMIT
MHR x upper target activity %.
E.g. Target activity is WALK:
Upper limit = MHR x 78%
HEART RATE ALERT
You can set the heart rate alert in the heart rate mode to the following
settings:

• 1 beep = you have gone below your lower
