6. Troubleshooting
If you encounter issues with your Rossmax HA500 thermometer, refer to the table below:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Dead or incorrectly installed battery | Replace battery, ensuring correct polarity. |
| Inaccurate or inconsistent readings | Sensor dirty; incorrect measurement distance; external factors (drafts, sweat); device not acclimatized. | Clean sensor; ensure 5cm distance; measure in a stable environment; allow device to stabilize at room temperature for 30 minutes. Take multiple readings for confirmation. |
| Display shows 'Lo' or 'Hi' | Temperature is outside the measurable range. | Ensure measurement is taken on a human body. If 'Lo' appears for body temperature, it indicates a very low temperature. If 'Hi' appears, it indicates a very high temperature. |
| Fever alarm sounds frequently | Actual high temperature; device malfunction. | Confirm reading with another reliable thermometer. If readings are consistently high, seek medical advice. If device seems faulty, contact support. |
If the problem persists after attempting these solutions, please contact Rossmax customer support.
