1 Please check to wear the Galaxy Watch Active2 correctly.
When you activate the auto heart rate tracking feature, or when the Galaxy Watch Active2 recognizes your exercise, the Galaxy Watch Active2 will automatically track your heart rate. When measuring your heart rate, wear the Galaxy Watch Active2 snugly on your arm above your wrist as shown in the figure below. If you fasten the Galaxy Watch Active2 too tightly, the skin irritation may occur and if you fasten it too loosely, friction may occur.

2 • Smoking or consuming alcohol before taking measurements may cause your heart rate to be different from your normal heart rate.

• Do not talk, yawn, or breathe deeply while taking heart rate measurements. Doing so may cause your heart rate to be recorded inaccurately.

• Because the heart rate sensor uses light to approximate heart rate, its accuracy may vary due to physical factors that affect light absorption and reflection, such as blood circulation/blood pressure, skin condition and location and concentration of blood vessels. In addition, if your heart rate is extremely high or low, measurements may be inaccurate.

• Users with thin wrists may receive inaccurate heart rate measurements when the device is loose, causing the light to be reflected unevenly. If heart rate measurement is not working properly, adjust the position of the device’s heart rate sensor to the right, left, up, or down on your wrist, or turn the device so the heart rate sensor sits firmly against the inside of your wrist.

• If the heart rate sensor is dirty, wipe the sensor and try again. Obstructions between the device’s band and your wrist, such as body hair, dirt, or other objects may prevent the light from reflecting evenly. Please make sure you remove such obstructions before use.

• If your device becomes hot to the touch, please remove it until it cools. Exposing skin to a hot surface of the device for a long time may cause skin burn.
