5. Maintenance

5.1 Cleaning the Chest Strap

After each use, it is recommended to rinse the elastic chest strap with clean water and hang it to dry. Do not use harsh chemicals or detergents, as this may damage the electrodes or fabric. The strap is replaceable if needed.

5.2 Battery Replacement

When the sensor's indicator light no longer flashes or connectivity becomes unreliable, it may be time to replace the CR2032 battery. To replace:

1. Gently twist the sensor module cover counter-clockwise to open it.
2. Remove the old CR2032 battery.
3. Insert a new CR2032 battery with the positive (+) side facing upwards.
4. Align the cover and twist clockwise to secure it.

The battery life is approximately 1 year, based on 5 hours of exercise per week.

5.3 Storage

Store the sensor and strap in a cool, dry place when not in use. Detach the sensor module from the strap for long-term storage to conserve battery life.

6. Troubleshooting

• No Heart Rate Reading:
  • Ensure the electrodes on the strap are moistened.
  • Check that the sensor module is securely snapped onto the strap.
  • Verify the strap is worn correctly and snugly on your chest.
  • Replace the CR2032 battery if it's old or if the indicator light is dim/off.
  • Ensure Bluetooth/ANT+ is enabled on your receiving device and the sensor is paired.
• Inaccurate Readings:
  • Re-moisten the electrodes.
  • Adjust the strap for a tighter fit.
  • Avoid wearing the sensor over loose clothing that might interfere with skin contact.
  • Ensure no strong electromagnetic interference nearby.
• Connectivity Issues:
  • Restart your phone/bike computer and the XOSS X2 sensor (by removing and reinserting the battery).
  • Forget the device in your phone's Bluetooth settings and re-pair.
  • Ensure you are within range of your receiving device.

8. User Tips

• Moisten Electrodes: Always moisten the electrode areas on the chest strap before wearing it. This significantly improves initial signal detection and accuracy.
• Snug Fit: Ensure the chest strap is snug enough to maintain constant skin contact but not so tight as to cause discomfort.
• Battery Check: If you experience intermittent readings or difficulty connecting, check the battery first. A fresh CR2032 battery can resolve many issues.
• App Updates: Keep your XOSS app and any other connected sports apps updated to their latest versions for optimal performance and compatibility.
• Post-Workout Care: Rinse the strap after each use to remove sweat and salts, which can corrode electrodes over time.
