- Open the app and create an account or log in.
- Ensure Bluetooth is enabled on your smartphone.
- Follow the in-app instructions to search for and pair with your KR96 Pro bracelet. The band needs to be connected to your phone via Bluetooth. Bluetooth will automatically connect when the app starts.
3. Wearing the Bracelet
Wear the bracelet snugly on your wrist, ensuring the sensors on the back are in good contact with your skin. This is crucial for accurate health monitoring. The screenless design offers a comfortable and snug fit.

Operating Instructions
The KR96 Pro smart bracelet operates primarily through its companion mobile application, as it is a screenless device. All data viewing, settings adjustments, and feature activations are performed within the app.
1. Health Monitoring Features
- Heart Rate Monitor: Continuously tracks your heart rate.
- Blood Oxygen Monitoring: Measures blood oxygen levels.
- Stress Monitoring: Provides insights into your stress levels.
- Sleep Monitoring: After activating sleep mode, the app generates professional sleep data, helping you understand your sleep patterns and providing suggestions for good sleep habits.
- ECG (Electrocardiogram): Utilizes a high-performance ECG sensor for 30-second ECG monitoring, enabling early detection and alerts for risks such as atrial fibrillation. Data is intelligently analyzed for abnormalities like sinus rhythm, atrial fibrillation, and premature ventricular contractions.
- Blood Components Monitoring: Measures and analyzes blood components including uric acid, total cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) to help understand your blood health status.
- Blood Pressure Monitoring: Monitors blood pressure changes throughout the day with dynamic, real-time tracking.
- Body Temperature Monitoring: Built-in sensor accurately measures your body temperature, keeping you informed of both high and low temperatures.
- HRV (Heart Rate Variability) Tracking: Real-time tracking and Lorenz Scatter Plot analysis provide an important indicator of the regulatory capacity of neural activity on the cardiovascular system.
- Menstrual Cycle Management: Tracks menstrual period, ovulation period, and safe period, including cycle prediction and period reminders.

2. Activity Tracking
The bracelet automatically tracks your daily activities:
- Steps Tracker: Counts your daily steps.
- Distance Tracker: Estimates the distance you've walked or run.
- Activity Tracker: Monitors various activities and calculates calories burned.
- Multi Exercise Modes: Built-in multiple sports modes for tracking specific workouts.

3. Smart Features
- Smart Wrist Assistant: Provides thoughtful reminders and can integrate with your digital life, such as displaying call notifications (as shown with a phone call interface).
- SOS/Remote Care: In case of sudden illness or other emergencies, elderly people living alone can use their smartwatches to call for help with a single click, notify emergency contacts, and allow relatives to remotely monitor their family's health.
4. Viewing Data
All monitoring data is viewed in real-time via the mobile application. Even without a phone connection, the band can independently monitor your health, recording blood oxygen and heart rate. Once connected, the data will be updated within the app.

Maintenance
1. Cleaning
Regularly clean your smart bracelet to ensure optimal performance and hygiene. Wipe the device and strap with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the sensors or finish.
