How to use Activity Settings on the watch?
Click the right button to enter the main menu and tap Workout, swipe up to access “settings”. You will have options to set auto pause, heart rate alert, pace alert, and distance alert.
Auto Pause: When auto pause is enabled, watch will automatically pause when you are resting or stop moving during your activity.
Heart Rate Alert: You can set a value to make the watch alert you when your heart rate jumps above the value you set.
Pace Alert: You can set a target pace to make the watch alert you when your pace is below the target pace.
Distance Alert: You can set the desired distance to alert you. (eg: vibration at each mile)
