Frequently Asked Questions (FAQ) 1. Question: Does the bracelet generate radiation? Does it hurt you when you wear it for a long time? Answer: As applying the low-power consumption Bluetooth technology, this product has less radiation than Bluetooth earphone, and its signal launching intensity is not more than1/4 that of mobile phone. WHO didn t find any impact of Bluetooth signal on human body through over ten years of research and general survey. So rest assured to use this product. 2. Question: What can I do if the bracelet is not searched as prompted? Answer: First, check the bracelet is energized or not; Second, Put the bracelet near the mobile phone, and try connecting the bracelet again. If you are still unable to connect the bracelet by above operations, try switching off and on the mobile phone Bluetooth once, or restart the mobile phone. 3. Question: Is the Bluetooth not connected accidently? Answer: 1. The connecting time may be different each time as the signal is disturbed in Bluetooth wireless connection. If it is not connected for a long time, make sure your operation is done in the place where there is no disturbance of magnetic field or Bluetooth device. 2. The Bluetooth services of some mobile phones may become abnormal accidentally in re-starting up, so that the Bluetooth may not be connected. 3. The mobile phone Bluetooth is connected normally when you restart the mobile phone. 4. Question: How are the data synchronized? How to deal with the case that the data is not synchronized? Answer: 1. Launch APP to connect and bind with the bracelet; 2.

Notes: The most upper menu can pop out the message when the mobile phone s message is coming, indicating the successful setting is completed. At the same time, the message is pushed to bracelet. If the mobile phone is restarted, click the Message prompt in Setting to enter notification center, and find out JYou device s message notification; then re-open the option. 7. Question: Why does my heart rate measure fail? Answer: Note to keep the user in a quiet status in measuring heart rate, and keep the bottom of bracelet closely attached to the arm without obvious gap. Don t wave arms during measurement. 8. Why is the Bluetooth connecting icon blinking all the time? Answer: The IOS user may encounter this problem. It mainly can prompt the users that the pushed message is not received if APP is not connected with bracelet. Launch APP to connect to bracelet, and the Bluetooth icon can be displayed normally. 12

9. Question: Why it can t be charged? Answer: 1. Check the bracelet inserting direction is right or not; 2. The battery has to undergo a pre-charging period when the electricity quantity for bracelet is too low (the bracelet has been set aside and not been used for a long time). Note: Generally charge by plugging in the charger; note that generally it enters the normal charging status after two or three minutes upon the charger is plugged in. 10. Question: Which factors can affect the measuring result of heart rate? Answer: Non-standard way of bracelet wearing may affect the measurement of heart rate. For example, the insufficient attachment of bracelet to skin which may cause light leakage, arm swinging, slight movement of bracelet on skin, too tight in bracelet wearing, too high in arm raising, and clenching fists, all of which may affect blood circulation as well as the signal of heart rate. The right measuring ways are: to put the arm at a level, take it easy and keep quiet, and make sure the bracelet is closely attached to the arm. Note that individual differences such as skin color,hair,tattoo and scar may also af fect the signal of heart rate even when the bracelet is worn properly. 11. Question: How to switch the bracelet language? Answer: The bracelet supports Chinese/English display. The language can synchronize with the language of the mobile phone system automatically. To switch the language, connect JYou APP to synchronize data, and the bracelet can keep its language synchronized with that of mobile phone. For example, if the mobile phone is in Chinese mode, then the bracelet can display Chinese after synchronization; if the phone is in Chinese mode, then the bracelet can display English after synchronization. Note: If the language is changed for bracelet, it required to restart the phone for synchronization after the mobile phone language is switched. 12. Question: Why is the time of bracelet inaccurate? Answer: Error may occur with the time of bracelet after the bracelet is recharged up when out of electricity. In this case, please connect the bracelet to the mobile phone, and the time of the bracelet will be synchronized automatically with that of the mobile phone for correction. Warning: Please consult your doctor before you take part in a new sport. The smart bracelet should not be used for medical purpose though it may monitor the real-time dynamic heart rate. 13
