9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display after power on | Batteries are dead or incorrectly inserted. | Replace batteries or reinsert them with correct polarity. |
| SpO2 or PR values are unstable | Finger not inserted properly; patient movement; cold finger. | Reinsert finger, ensure stillness, warm the finger if cold. |
| Bluetooth connection fails | Bluetooth off on phone; app not open; device out of range. | Ensure phone Bluetooth is on, open the app, keep device close to phone. |
| "Error" message on display | Sensor malfunction or severe signal interference. | Remove finger and re-attempt measurement. If error persists, contact support. |
