How to use
Insert batteries into the main unit (3 × AA) and into each transmitter (2 × AAA), then place transmitters outdoors or in required locations within the recommended operating range. Allow the units to synchronize via the 433 MHz link; the main unit will receive temperature and humidity data from paired transmitters and display time after radio-controlled synchronization. Use the menu controls to select 12/24-hour format, set the alarm and view max/min stored values for the hygro-thermometer. Position the main unit where the display is easily visible and the transmitters in sheltered outdoor spots for reliable readings.
Usage recommendations
For accurate outdoor measurements, install transmitters in shaded, ventilated locations protected from direct rain and strong sunlight. Replace batteries before low-battery indicators affect transmission and check transmitter placement if signal reception is weak; keep the distance between main unit and transmitters within the specified range for stable communication.
