Operating Instructions
Power On/Off
- To power on, press and hold the button (if present, otherwise assume automatic activation upon wearing or movement).
- To power off, press and hold the button until the device indicates shutdown.
Heart Rate Monitoring
The device continuously monitors your heart rate. The colorful indicator light provides a quick visual reference of your current heart rate zone:
| Indicator Color | Heart Rate Zone | Description |
|---|---|---|
| Z4 | 90%-100% | Anaerobic endurance, increasing the limit |
| Z3 | 80%-90% | Lactate threshold, improve muscular endurance |
| Z2 | 70%-80% | Aerobic exercise, improve heart and lungs |
| Z1 | 60%-70% | Fat burning process |
*When the heart rate zone is below 60%, the light shows white by default.

Heart Rate Alert
To ensure safety during exercise, the armband will flash a red light and vibrate to remind you when your heart rate reaches your preset maximum value. This feature helps prevent overexertion.
Independent Data Storage
The Beat Band Pro can record exercise data independently, meaning you don't need to be constantly connected to a bike computer or smartphone app during your workout. Data can be synced later.

Blood Oxygen Monitoring
To check your blood oxygen level and plan your exercise scientifically, connect the device to the XOSS app. The app will display the readings and provide insights.
Calorie, Speed & Distance Estimation
The device estimates calories burned, speed, and distance based on your movement and personal data (cadence, height, gender, etc.). This helps in arranging your exercise and weight management.

Maintenance
- Cleaning: After each use, especially after intense workouts or swimming, gently wipe the device and strap with a soft, damp cloth. Do not use harsh chemicals or abrasive materials.
- Charging: Charge the device regularly to maintain battery health. Avoid completely draining the battery frequently.
- Storage: Store the Beat Band Pro in a cool, dry place away from direct sunlight and extreme temperatures.
- Water Exposure: While IP68 waterproof, it is recommended to rinse the device with fresh water after exposure to chlorinated or saltwater to prevent corrosion. Ensure it is dry before charging.

Troubleshooting
- Device Not Turning On: Ensure the device is fully charged. If it still doesn't turn on, try a different charging port or cable.
- Inaccurate Heart Rate Readings:
- Ensure the sensor is clean and in direct contact with your skin.
- Tighten the strap slightly to prevent movement, but avoid making it uncomfortably tight.
- Avoid wearing it over tattoos or thick hair, which can interfere with sensor accuracy.
- Connectivity Issues with App/Bike Computer:
- Ensure Bluetooth is enabled on your smartphone or bike computer.
- Restart both the Beat Band Pro and the connecting device.
- Make sure the XOSS app is updated to the latest version.
- Data Not Syncing: Ensure the device is within Bluetooth range of your smartphone/bike computer and the app is open. Check the app's settings for manual sync options.
