How to use

Place the thermometer at eye level on a wall or on a stable flat surface away from direct sunlight, heating sources and drafts to ensure accurate ambient readings. Insert the required batteries according to the device’s battery compartment markings, switch the unit on if a power control exists, and allow a few minutes for the sensor to stabilise to room conditions before taking readings. Read the temperature value directly from the digital display; for consistent monitoring, check the thermometer at similar times or locations within the room.

Usage recommendations

For best accuracy, avoid installing the thermometer near windows, radiators, air conditioners or ventilation outlets. Replace batteries before they become weak to prevent display errors, and clean the housing with a dry or slightly damp cloth — do not use solvents. Use multiple units in larger rooms if you require temperature comparison across different areas.
