2.2 Wearing the Monitor
For accurate heart rate measurement, the HS500 sensor must be worn correctly on your chest.
- Moisten the electrode areas on the back of the chest strap with water or electrode gel. This improves conductivity.
- Attach the sensor unit to the two snap fasteners on the chest strap. Ensure it is securely fastened.
- Place the chest strap around your chest, just below your pectoral muscles. The sensor unit should be centered on your sternum.
- Adjust the strap length to ensure a snug but comfortable fit. It should be tight enough to stay in place during activity but not restrict breathing.

5. Troubleshooting
If you encounter issues with your GEOID HS500 Heart Rate Monitor, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No heart rate reading / Device not detected | Dry electrodes, loose strap, dead battery, incorrect pairing method. | Moisten electrodes, adjust strap for snug fit, replace battery, ensure pairing via app (not phone's Bluetooth settings). |
| Inaccurate heart rate readings | Poor contact, electrical interference, sensor displacement. | Re-moisten electrodes, reposition sensor, ensure no strong electromagnetic fields nearby. |
| LED light not flashing | Battery issue, sensor not worn correctly. | Check/replace battery, ensure sensor is snapped onto strap and worn on chest. |
| Difficulty connecting to app/device | App/device compatibility, Bluetooth interference, incorrect pairing. | Verify app/device compatibility, restart app/device, ensure no other Bluetooth devices are interfering, pair only through the app. |
If the problem persists after trying these solutions, please contact GEOID customer service for further assistance.
