1. Maintain a Bluetooth connection between the hand ring and your phone.
2. The hand ring displays up to the 5 most recent messages, with an icon indicating the number of new messages.
3. Press and hold on a message to delete it from the hand ring. 

1. The Veryfit app syncs automatically upon opening, or you can manually sync by pulling down the message list on the app’s main interface.
2. If synchronization fails, try these steps:

• Retry pulling down in the app for synchronization.
• Close and reopen the Veryfit app.
• Switch the phone's Bluetooth off and on, or restart the phone.
• For persistent issues, clear Bluetooth sharing settings in your phone's settings before restarting. 

1. Steps counting, sleep tracking, and alarm clock functions don’t require a continuous Bluetooth connection to the phone. For workouts, sync the hand ring with the phone afterwards to view data.
2. Set alarms via the Veryfit app. Once set, the alarm functions without a Bluetooth connection.
3. For call reminders and using the 'find hand ring' feature, keep your phone's Bluetooth on and connected to the hand ring. 

1. The hand ring independently stores data, so there's no need to carry your phone for activities like running or sleeping. Simply connect via Bluetooth to sync data later.
2. It retains up to 7 days of activity data, ensuring no loss of information before synchronization. 

To enhance the accuracy of your smartwatch's step tracking, we've implemented a system that sets an initial value of 10 steps. Once you take more than 10 real-time steps, the formal step counting begins, and you'll notice the step count on the main app interface update accordingly. In other words, your step count begins at the 10th step, and the data for the steps taken between 10 and 30 are stored for your reference. 

By default, when you set up a call reminder, the smartwatch will vibrate for 3 seconds to alert you to incoming calls. However, in the Veryfit app, you have the flexibility to customize the call reminder duration to suit your personal preferences and needs. 

Unfortunately, you cannot modify the number of vibrations for call reminders. When a call reminder is activated, the smartwatch will vibrate continuously until the call is either answered or disconnected. You can also stop the vibration reminder manually by touching the touch key during the call notification process.

1. Ensure that your Bluetooth on your phone is enabled and properly connected to the smartwatch.

2. If you're using a non-iOS system, make sure that the Hand Ring app is running, even if it's in the background. 

1. The mobile phone should not be in a dormant state, and background processes must remain active.
2. Ensure that you are not actively using the same application on both your computer and mobile phone simultaneously, as this can interfere with the notifications.
3. Maintain a consistent connection between your smartwatch and your mobile phone, with Bluetooth enabled at all times. 

1. Wearing Position: Wearing the device incorrectly or loosely can lead to inaccurate readings. Ensure that the device is snugly fitted on your wrist.
2. Body Movement: Excessive arm movement or vibrations can affect the heart rate signal. It's best to stay still and relaxed during measurements.
3. Wristband Tightness: Wearing the wristband too tight or too loose can influence blood circulation and, consequently, heart rate readings. Find a comfortable fit.
4. Arm Position: Keeping your arm raised or clenched can disrupt blood flow and heart rate signals. Maintain a relaxed arm position.
5. Skin Variations: Skin color, the presence of hair, tattoos, and scars can introduce variability in heart rate readings, even when wearing the device correctly. 

1. The first digit represents the level of protection against dust and solid particles. In this case, a rating of "6" indicates a high degree of dust resistance, preventing the entry of most solid particles.
2. The second digit represents the level of waterproof protection. An "7" rating signifies that the product is capable of withstanding immersion in water up to a certain depth for a specified duration without sustaining damage. 

1. User Information: Ensure that you input accurate information such as gender, height, weight, and age when you first set up your smartwatch. This information directly influences the data captured by the accelerometer sensor and the functioning of the tracking algorithm. Inaccurate input can lead to incorrect step counts, inaccurate distance measurements, and unreliable calorie consumption estimates.
2. Wrist Movement: Your arm's motion pattern, including how you swing your arm while walking, can affect the smartwatch's ability to detect steps accurately.
3. Stride Length: The length of your stride also plays a role in step tracking accuracy. An incorrect stride length can result in under- or over-reporting of steps.
4. Body Shape: Your body's physical characteristics, such as height and weight distribution, can impact the way your smartwatch interprets your movements.
5. Terrain and Environment: The surface you're walking on, whether it's smooth or uneven, as well as inclines or declines, can influence step count accuracy. 

1. Enabling location permissions for Veryfit allows the app to automatically detect your current city for weather data. If it can't determine your location, the weather information may be unavailable. Turning on GPS can improve location accuracy.
2. When your smartwatch and Veryfit app are in a normal connected state, the app periodically sends weather forecasts to the smartwatch. In cases of poor network service, weather data may update asynchronously or display as "no data."
3. If your smartwatch becomes disconnected from Veryfit, weather data won't sync in real-time. If historical data exists, it will be displayed. If there's no historical data, the weather information will show as unavailable.
