Guía de configuración
1. Instalación da batería
Both the main display unit and the wireless outdoor sensor require batteries (not included).

2. Colocación do sensor
Proper placement of both units is crucial for accurate readings and reliable wireless communication.
- Unidade de visualización principal: Place indoors, away from direct sunlight, heat sources, or drafts that could affect temperature and humidity readings. Ensure it is within 30 meters (100 feet) of the outdoor sensor.
- Sensor exterior sen fíos:
- Mount in a shaded area to avoid direct sunlight, which can cause artificially high temperature readings.
- Protect from direct rain and snow. An overhang or a weather-resistant enclosure is ideal.
- Avoid placing near large metal objects, electrical appliances, or thick walls that could interfere with the wireless signal.
- Ensure it is within the 30-meter (100-foot) wireless range of the main unit.
