## Long description

The Indoor Outdoor Hygrometer GARNI GARNI439 Line Black AC Thermometer is a compact weather-monitoring device designed for household use.

How to use
Place the main unit indoors on a stable surface or mount it on a wall where the display is easily visible. Install the outdoor sensor in a sheltered outdoor location away from direct sun and precipitation but exposed to ambient air for accurate readings. Connect the main unit to AC power and insert a 3V battery if required for backup operation. Allow several minutes for the outdoor sensor signal to synchronize with the base unit; the display will show both indoor and outdoor temperature and humidity along with the temperature trend. Adjust placement of the sensor or main unit as needed to obtain stable signal reception and accurate environmental readings.
Usage recommendations
To ensure accurate measurements and reliable wireless transmission, avoid placing the outdoor sensor near heat sources, direct sunlight or heavy metallic obstructions. Regularly check battery status if using the 3V backup and perform periodic cleaning of the sensor housing to prevent dust accumulation that could affect humidity readings.
