8.0 Heart Rate Alert Function
About the Heart Rate Alert Function
By presetting a target heart rate range, you can activate the heart
rate alert function. This function helps prevent the user from going
over or under a target heart rate.
In course of doing exercise or sports: When the user takes a heart
rate measurement that is out of the preset desirable range, this
watch will beep twice. Hence, the user could render the appropriate
actions such as slowdown or speed up the exercise.
For example, some training sessions may require the trainee
maintaining his / her heartbeat at a predefined range (the desirable
range) to achieve training objective. This watch can remind the
trainee whether his/her heartbeat is out of the objective range all
the time.
Upper & Lower Limits and Desirable Heart Rate Range
The desirable heart rate range is the realm that defined by the upper
and lower limits.
1) Get the limits by consulting a doctor or trainer.
2) Calculate the limits by using the user’s age andgender.
Check the coming ‘8.2 Setting the Heart Rate Alert Mode’ Section
for more detail on setting the Limits.
