How to use
Install AA batteries in the main unit and any external transmitters, then allow the unit to register the connected sensors. Place the outdoor transmitters where they are protected from direct rain and sunlight but exposed to the ambient air you want to measure. Use the menu to set the time zone, enable the radio-controlled clock, and configure alarm thresholds for temperature and humidity. Access stored measurements on the device display or connect the unit to a PC via USB to download logged data for analysis.
Usage recommendations
For reliable humidity readings, position the indoor sensor away from heaters, windows with direct sunlight, or kitchen steam sources. For outdoor sensors, avoid placing them in direct sun or where they would be soaked by rain; a shaded, ventilated mounting gives the most representative measurements.
