Setup and Installation
Before first use, ensure the insulating paper is removed from the battery compartment.

Speed Mode Installation
To install the Vortex sensor for speed measurement:
- Tighten the strap around the hub of either the front or rear wheel of your bicycle.
- Ensure the sensor bypasses the hub and is securely hooked.

Cadence Mode Installation
To install the Vortex sensor for cadence measurement:
- Measure the crank clearance to ensure it meets installation requirements.
- Use the straps to bypass the pedal crank and securely hook the cadence sensor.

Operation
Mode Switching
The Vortex sensor can switch between speed and cadence modes. This can be done via the XOSS APP or by reinstalling the battery.

To switch modes by reinstalling the battery:
- Turn to unlock and unscrew the back cover of the sensor.
- Remove the battery, wait a few seconds, and then reinstall it.
- Turn on the back cover and tighten it securely.
- The current mode will be indicated by the front indicator light.

Connectivity
The Vortex sensor supports ANT+ and BLE dual-mode connections, making it compatible with a wide range of cycling computers, smartwatches, and sports apps.

Smart Features
- Scientific Riding Training: Master your cadence data to optimize your training.
- Enhanced Speed Calculations: Measure riding speed accurately even without a GPS signal.
- Intelligent Energy-Saving: The sensor automatically switches between working and sleep modes. If no movement or vibration is detected for 3 minutes in working state, it enters dormant state to conserve battery. Any movement will wake it up.

X2 Heart Rate Monitor
Product Overview
The XOSS X2 Heart Rate Monitor provides accurate heart rate data for various sports activities, helping you train more scientifically.

Specifications
| Feature | Detail |
|---|---|
| Wireless Protocol | ANT+, BLE (Dual Protocol Support) |
| Battery Model | CR2032 Lithium Button Cell |
| Battery Life | Up to one year (based on exercise 5 times a week for approx. 1 hour each time) |
| Waterproof Level | IP67 |
| Indicator Light | Yes |

Setup and Installation
The X2 Heart Rate Monitor comes with:
- 1x Heartrate Sensor
- 1x Elastic Chest Strap
- 1x CR2032 Lithium Button Cell

To use the X2 Heart Rate Monitor:
- Insert the CR2032 battery into the sensor.
- Attach the sensor to the elastic chest strap.
- Wear the chest strap around your chest, ensuring the sensor is positioned correctly for accurate heart rate detection.
- Before connecting to any app or device for the first time, confirm that you have worn the XOSS X2 properly.
Operation
The X2 Heart Rate Monitor is compatible with mainstream sports apps and devices via ANT+ and BLE. This includes XOSS, Zwift, Wahoo, Garmin, and various sports watches and cycling platforms.

The XOSS APP provides powerful features for scientific training, including detailed data recording, charts, and analysis of heart rate zones.

The X2 is suitable for a wide range of sports activities, including running, cycling, and swimming.

Maintenance
Battery Replacement
Both the Vortex Speed and Cadence Sensor and the X2 Heart Rate Monitor use CR2032 button batteries.
- To replace the battery, carefully unlock and unscrew the back cover of the device.
- Remove the old battery and insert a new CR2032 battery, ensuring correct polarity.
- Securely reattach and tighten the back cover to maintain the waterproof seal.

Cleaning
The Vortex sensor (IPX7) and X2 Heart Rate Monitor (IP67) are waterproof and resistant to sweat and rain. Clean the devices with a soft, damp cloth. Do not use abrasive cleaners or solvents.


Troubleshooting
- Sensor not detected:
- Ensure the device's battery has sufficient charge and the insulating paper has been removed (for first use).
- Check that the sensor is correctly installed and within range of your receiving device.
- Verify that Bluetooth or ANT+ is enabled on your receiving device.
- Incorrect mode (Vortex Sensor):
- If the Vortex sensor is in the wrong mode (e.g., speed when you need cadence), switch modes via the XOSS APP or by reinstalling the battery as described in the "Operation" section.
- No speed/cadence data simultaneously (Vortex Sensor):
- The Vortex sensor can only operate in one mode (speed or cadence) at a time. To obtain both speed and cadence data simultaneously, you will need two separate Vortex sensors.
- Note: The Bluetooth connection protocol may temporarily be unable to connect speed and cadence data at the same time, even with two sensors. ANT+ is generally more reliable for simultaneous connections.
- Inaccurate heart rate data (X2 Heart Rate Monitor):
- Ensure the X2 Heart Rate Monitor is worn properly and snugly against your skin, just below your chest muscles.
- Moisten the electrodes on the chest strap with water or electrode gel for better conductivity.
- Check the battery level.
User Tips
- For optimal performance and data tracking, download and use the official XOSS APP. It provides comprehensive data recording, charts, and analysis.
- Regularly check the battery level of your sensors to avoid interruptions during your rides.
- When installing the Vortex sensor, ensure it is firmly secured to prevent movement that could affect accuracy.
- For the X2 Heart Rate Monitor, moistening the electrodes before wearing can significantly improve initial data acquisition.
