To exit the heart rate detection mode, long press the button for 3 seconds in the heart rate
detection mode.
4.1 Please put on your watch on your wrist, 2cm from the inside of your ulnaradius joint.
4.2 When measuring your heart rate, keep the heart rate sensor clung to your skin and in
good contact. Otherwise, the light of the sensor may leak and the measurement data may
be incorrect.
Do not look directly at the green light of the sensor, which may cause discomfort to your
eyes.
4.3 Though this watch can detect your real-time heart rate dynamically, you are still
recommended to keep still during heart rate detection. Otherwise, it may take a longer
time to measure the heart rate or you may get incorrect data. After the watch has
measured the data, you can do exercise again and view the dynamic data.
4.4 If great difference exists between measurements, please have a rest and make another
measurement. If you make 5 successive measurements and take their average value, you
will get a correct result.
