4. Maintenance
To ensure the longevity and accuracy of your Goabroa Mini Hygrometer Thermometer, follow these simple maintenance guidelines:
- Cleaning: Wipe the device clean with a soft, dry cloth. Avoid using abrasive cleaners or submerging the device in water.

5. Troubleshooting
If you encounter issues with your device, consider the following:
- No Display/Dim Display: Check or replace the LR44 batteries. Ensure they are inserted with correct polarity.
- Inaccurate Readings:
- Ensure the device's vents are not blocked.
- Allow the device to stabilize for at least 30 minutes after initial setup or relocation.
- Note that minor differences in readings (e.g., +/- 1°F or +/- 1% RH) between multiple devices, even in the same location, are considered normal due to sensor tolerances.
- Avoid comparing with wall-mounted monitors whose sensors might be in different environments (e.g., ceiling or outdoors).
- Temperature Unit Change: This model displays temperature in Fahrenheit (°F) only. There is no option to switch to Celsius.
