Identify Common Causes
- Sensor Blockage: Dirt, sweat, or physical obstructions can prevent the heart rate sensor from working. The optical sensor must be clean and in direct skin contact.
- Poor Fit: A loose or too-tight strap can affect the reading. It should be snug but not constricting.
- Software Issues: Outdated software can cause malfunctions. Check if there is a new firmware update available.
- Low Battery: Insufficient power can cause performance issues. Ensure the watch has enough charge.
- Non-compatible Modes: Certain modes like Sleep Track might not have heart rate tracking enabled.
Steps to Fix the Problem
- Clean the Sensor: Gently clean the back of the watch with a soft cloth. Ensure no dirt or sweat is blocking the sensor.
- Adjust the Strap: Make sure the watch is worn correctly. It should be comfortable but tight enough to keep proper contact with the skin.
- Update Software: Connect the Garmin device to a computer and use Garmin Express to check and install any available updates.
- Charge the Device: Fully charge the watch to avoid any issues related to low power.
- Check Modes: Ensure the correct mode is selected. Go into the settings and check if heart rate tracking is enabled in the active mode.
- Restart the Watch: Sometimes a simple restart can resolve technical glitches. Turn the watch off, wait a moment, and turn it back on.
- Contact Support: If none of the above solutions work, contact Garmin support for further assistance.
Preventive Tips
- Regular Maintenance: Regularly clean the sensor to avoid dirt buildup.
