During the charging and activation, the charging indicator on the ring will turn red, indicating that the ring is turned on. For the first use, please keep charging for more than 1 hour until the charging indicator on the ring turns green.

Due to the consideration of saving system resources, some mobile phone systems may disable Ring‘s APP that users have not set up background protection in the background.Therefore, please refer to the background protection guide and enable APP's background protection function. lf APP is already turned on and still shows disconnected, it is possible that the ring has shut down due to low battery. Please charge it before reconnecting.

1. Use tools for cleaning. Cotton swab: Cotton swab is a very convenient cleaning tool that can be used to clean the dust on the charging port. Just gently turn the cotton swab to clean the surface dust. Toothpick: If there is a lot of dust around the charging port, you can use a toothpick to clean it. But be careful not to use a toothpick that is too thick to avoid damaging the charging port.
2. Cleaner If the dust on the charging port is stubborn, you can use some cleaner to clean it. But be careful to choose a mild cleaner to avoid damaging the ring. At the same time, pay attention to the amount and method of using the cleaner to avoid corrosion or damage to the charging port.
3. Precautions: Pay attention to the method and strength when cleaning, and do not use too rough methods to avoid damaging the charging port. If the charging port is damaged or cannot be cleaned, it is recommended to contact customer service for help.

Use a qualified mobile phone charger or computer USB port to connect the charging cable or charging case to charge the ring. When the ring is charging, the red light on the ring indicates that it is charging, and the green light indicates that it is fully charged.

In order to reduce the user's daily activities, such as typing on the keyboard, playing poker, and other frequent hand activities, which cause the ring's step counting error, the ring sets a threshold. When the number of steps reaches 10 in a row, the step counting will officially start, and the real-time step count in the QRing main interface will change.

After the user completes the first ring binding, when the APP is opened again, the ring will automatically connect to APP and start synchronizing data;

At this time, the user does not need to do anything. If the connection fails, please charge it and check again whether it can connect to APP and synchronize data.

Click the sync button in the upper right corner of the application to automatically synchronize the current data of the ring.

Sure, the ring is 5ATM waterproof. But please try not to use it in complex water environments (such as hot springs, seawater). If the ring contacts seawater, please rinse it with fresh water as soon as possible to avoid corrosion of the metal material on the ring by the salt in the seawater, resulting in poor contact of the ring charging position.

The health index is obtained by comprehensively evaluating the sleep, exercise, stress, heart rate and blood oxygen data collected by the ring. Among them, sleep data is the most basic data. If the wearing time is too short or there is no sleep data, the health index cannot be generated. It is recommended that you continue to wear the ring to unlock your health index.

Keep the Bluetooth connection between the ring and the mobile phone; click the remote photo button in APP; shake the hand wearing the ring lightly to complete the photo.

The time of falling asleep and waking up is marked by changes in the physiological characteristics of the human body when entering and waking up from sleep.The sleep state is detected through sensors inside the ring, which may have a certain time deviation from one's actual.

The human sleep process consists ofvarious sleep states such as light sleep,deep sleep, and wakefulness. ln a conscious state, most people's body consciousness is still very vague, and users may not be aware of their tendency state, resulting in a deviation between personal feelings and ring detection and recording data.

Sleep detection is achieved through sensors on the ring that detect human activity characteristics. lf a user maintains the same posture for a long time without moving, it may be recognized as entering a sleep state.

The normal operating temperature for the ring is -10~+45℃(14~113 °F).If stored or worn outside the normal temperature range for a long time, it will affect the lifespan and reliability of the ring, which may affect its normal use.
