4. Setup
Follow these steps to set up your XOSS Heart Rate Monitor:
- Unpack the Device: Carefully remove the heart rate sensor, elastic chest strap, and any other accessories from the packaging.
- Adjust the Chest Strap: Adjust the length of the elastic chest strap to comfortably fit around your chest, just below your pectoral muscles.
- Moisten Electrodes: Lightly moisten the electrode areas on the back of the chest strap with water or electrode gel. This improves conductivity and ensures accurate heart rate detection.
- Wear the HRM: Securely fasten the chest strap around your chest. The sensor module should be centered on your sternum.
- Activate the Sensor: Once worn correctly, the HRM will automatically detect your heart rate signal. It will emit two beeps and a green light will flash, indicating it has started working.
Connecting to a Bike Computer (e.g., XOSS G+)
- Ensure your XOSS HRM is worn and active (green light flashing).
- On your bike computer (e.g., XOSS G+), long-press both buttons simultaneously to enter the pairing interface.
- The bike computer will automatically search for and pair with the HRM, displaying your heart rate data once connected.

Connecting to a Fitness App (e.g., XOSS APP)
IMPORTANT NOTICE: Do NOT pair the HRM directly from your cellphone's Bluetooth settings. It will not work properly. Always pair the HRM via the Bluetooth settings within your fitness application.
- Ensure your XOSS HRM is worn and active (green light flashing).
- Open your preferred fitness app (e.g., XOSS APP) on your smartphone.
- Navigate to the 'Devices' or 'Sensors' section within the app.
- Select 'Heart Rate Monitor' or 'Add Sensor' and choose the XOSS HRM from the list of available devices.
- The app will connect to the HRM and display your real-time heart rate data.

5. Operating Instructions
Once properly set up and connected, the XOSS Heart Rate Monitor operates automatically:
- Automatic Activation: The sensor activates when it detects a heart rate signal, indicated by two beeps and a flashing green light.
- Data Transmission: It continuously transmits your heart rate data via Bluetooth and ANT+ to your paired device (bike computer, smartwatch, or fitness app).
- Automatic Sleep: The device features automatic sleep mode to conserve battery when not in use.
- Auto-Pause: The auto-pause function helps in accurate tracking during activities with intermittent stops.
- X2 Pro Independent Storage: If you have the X2 Pro model, it can store data independently, allowing you to review detailed metrics like estimated calories, distance, and speed even without a connected device during your workout.

6. User Tips
- Compatibility: The XOSS X2/X2 Pro is widely compatible with devices supporting Bluetooth and ANT+ protocols. This includes many Garmin devices (e.g., Garmin 955, Garmin Edge), Bryton bike computers (e.g., Bryton 310, Bryton 320), Bosch Kiox 300 displays, Strava, and Cycplus M1.
- App Pairing: Always pair the heart rate monitor through your fitness app's settings, not directly through your phone's Bluetooth settings, to ensure proper functionality.
- Moisture is Key: Ensure the electrode areas on the chest strap are adequately moistened before each use for reliable heart rate detection.
- Chest Strap Design: This device is designed as a chest strap heart rate monitor. It is not intended for arm wear.
- Battery Life: The battery life is approximately one year based on typical usage (e.g., 5 times a week for 1 hour each time). Actual battery life may vary depending on usage patterns.
7. Troubleshooting
- No Heart Rate Signal:
- Ensure the chest strap is worn correctly and snugly against your skin.
- Re-moisten the electrode areas on the strap.
- Check the battery. If the green light does not flash or the device does not beep upon wearing, the CR2032 battery may need replacement.
- Connectivity Issues (Device/App):
- Confirm that your receiving device (bike computer, app) supports Bluetooth or ANT+ and is within range.
- Ensure you are pairing through the fitness app's settings, not directly via your phone's Bluetooth.
- Try unpairing and re-pairing the HRM with your device/app.
- Restart your fitness app or bike computer.
- Inconsistent Readings:
- Ensure good contact between the electrodes and your skin by moistening them.
- Check for any interference from other electronic devices.
- The strap might be too loose or too tight. Adjust for a comfortable, secure fit.
- Short Battery Life:
- If a new battery lasts only a few hours, ensure the device is entering automatic sleep mode when not in use.
- Verify the battery is a fresh, high-quality CR2032.
8. Maintenance
- Cleaning the Strap: After each use, detach the sensor module from the chest strap. Rinse the elastic strap under running water and hang it to dry. Do not machine wash or tumble dry.
- Cleaning the Sensor: Wipe the sensor module with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: The XOSS X2/X2 Pro uses a CR2032 button cell battery. To replace, open the battery compartment on the back of the sensor module, remove the old battery, and insert a new CR2032 battery with the positive (+) side facing up. Ensure the compartment is securely closed to maintain water resistance.
- Storage: Store the heart rate monitor in a cool, dry place when not in use. Do not store the sensor module attached to the wet strap for extended periods.
