6. Maintenance
6.1 Cleaning
- Clean the stainless steel probe with a damp cloth and mild detergent before and after each use.
- Wipe the main body of the thermometer with a clean, damp cloth. Do not immerse the entire unit in water.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermometer does not turn on. | Dead or incorrectly installed battery. | Check battery polarity. Replace battery if necessary. |
| Inaccurate readings. | Probe not fully immersed; calibration issue; extreme ambient temperature. | Ensure probe tip is correctly positioned. Refer to calibration instructions (if available) or contact support. Allow thermometer to acclimate to ambient temperature. |
| Display shows "LO" or "HI". | Temperature is outside the thermometer's measurable range. | The thermometer is functioning correctly but the measured temperature is beyond its limits. |
| Display shows "ERR". | Sensor malfunction or internal error. | Turn the thermometer off and then on again. If the error persists, contact customer support. |
