2. Heart rate 24h monitoring is enabled;
3. sleep monitoring is enabled;
4. 50 pushed messages a day;
5. raise wrist to see watch time 100 times;
6. test blood-oxygen 2 times per day;
7. workout 2 times a week for 30 minutes at a time.

Wearing

(1) How to wear

1. Put the watch on your arm with the display facing up.
2. Thread the band through the buckle.
3. Insert the stick into the small hole of the band with a comfortable position on your wrist and fix it.

(2) How to take off

1. Pull the band out of the buckle.
2. Pull out the stick from the small hole.
   TIPS: Please take off the watch on a desk or somewhere soft in case of falling down or being damaged.
   

(3) How to exchange

1. To remove the wristbands, turn over the watch and find the quick-release lever.
2. While pressing the quick-release lever inward, gently pull the wristband away from the watch to release it.
3. Repeat on the other side.

(4) How to assembly

1. To reattach the wristbands, slide the pin (the side opposite the quick-release lever) into the notch on the watch. Attach the wristband with the clasp to the top of the watch.
2. While pressing the quick-release lever inward, slide the other end of the wristband into place.
   

For optimized heart rate tracking, keep these tips in mind:

1. Experiment with wearing the watch higher on your wrist during exercise. Because the blood flow in your arm increases the farther up you go, moving the watch up a couple of inches can improve the heart rate signal. Also, many exercises such as bike riding or weight lifting require you to bend your wrist frequently, which is more likely to interfere with the heart rate signal if the watch is lower on your wrist.
2. Do not wear your watch too tight. A tight band restricts blood flow, potentially affecting the heart rate signal. This being said, the watch should also be slightly tighter (snug but not constricting) during exercise than during all-day wearing. ]

To measure heart rate manually on the smart watch:

Steps: Slide up within the Home screen page to go to the features list > tap the “ Heart rate” icon >Heart rate is measuring

Principle of heart rate monitor:

Blood will have strong absorption of green light. When the heartbeat occurs, blood will flow through the part where the green light is located, and the blood will absorb the green light, leading to the weakening of the reflected green light. In this way, the intensity of the green light measured by the light sensor will be weakened, and a heartbeat can be detected.

Tips:

Time is incorrect

Time on the watch will completely follow the same as the phone’s settings. It cannot be changed on the watch separately.

1. Connect the watch to the phone.
2. Pull down the ‘Status’ page to synchronize the data.
   

Incorrect sleep record

Due to all smartwatches just could use the PPG to record sleep, it will be a bit of a deviation from reality. The smartwatch will is judged your sleep by your movement status and heart rate. If you wake up and don’t move in bed, you’re also considered asleep.

Incorrect steps

We use the hand swing to calculate the number of steps, in order to reduce the error, we set the threshold of the number of steps. Currently, only up to 15 consecutive steps are counted as steps. If the steps are more than two seconds apart, the step count restarts. For example, if you take 14 steps in a row, stop for three seconds, and then take 14 steps in a row, our watch will count as zero steps.
If you walk 15 steps in a row, stop for two seconds, and take 15 steps in a row, our watch will count as 30steps.

Incorrect heart rate.

1. Principle:
   The blood will have a strong absorption of green light, when the heartbeat occurs, blood will flow through the part where the green light is, the blood will absorb the green light, resulting in the reflection of the green light, so that the intensity of the green light measured by the light will be weakened, and a heart beat can be detected.

2. Possible causes:
   Dry skin, dark skin, too thin or too fat (affecting capillary density), excessive hair, relative movement between the watch and the hand, too tight (pressing capillaries), and too loose (reflected green light will be interfered with by ambient light).

3. Resolution:
   Don’t wear too tight also don’t wear too loose. Thin people wear the watch two to three fingers’ width from the wrist.

Incorrect blood oxygen.

1. Principle:
   Since oxygenated hemoglobin and deoxygenated hemoglobin have different absorbability to red and infrared (invisible) light, bleeding oxygen can be calculated by detecting the reflectance intensity of red and infrared light.

2. Possible causes: Dry skin, dark skin, too thin or too fat (affecting capillary density), excessive hair, relative movement between the watch and the hand, too tight (pressing capillaries), and too loose (reflected green light will be interfered with by ambient light).
