 Per KM alert
When you reach the predefined kilometers during workout, the watch vibrates to notify
you of the kilometers you have completed and displays your pace or speed over the last
kilometer. Before you use the Per KM alert feature, go to the Workout Settings screen
to turn on the Distance Alert.
 Insufficient free space alert
If the system has insufficient free storage space while you are working out, the watch
vibrates to ask you whether to continue the workout. If you tap Continue, the system
overwrites unsynchronized workout data. If you tap End, the system ends the current
workout.
 No free space alert
If the system has no free storage space left feature while you are working out, the watch
vibrates to notify you. In this case, the system automatically stores your current workout
record.
