Remarks:
This device is designed for indoor use. The comfort index is only related to the indoor relative humidity
change assuming the indoor temperature is normal at 18°C to 24°C. The comfort index will become less
relevant when the indoor temperature goes out of that indoor temperature range.
Trouble shooting
In case your thermo-hygrometer shows irrelevant information or digits, it maybe affected by electrostatic
discharge or interferences from other devices. Press the RESET button on the back of your unit. Your unit
will be reset and starts to measure fresh temperature and humidity data again.
Battery replacement
If you observe a low battery icon on the lower right LCD, which means your thermo-hygrometer is at low
battery level, take out the batteries and replace with fresh ones.
