3. Recursos do Produto
- Wide Range & High Accuracy: The thermometer features a 3-channel system with three transmitters for monitoring temperature and humidity in multiple locations. It offers an indoor temperature range of 0°C to 60°C (32°F to 140°F) and an outdoor temperature range of -40°C to 60°C (-40°F to 140°F). Humidity is measured from 10% to 99%. Accuracy is ±1°C (±1.8°F) for temperature and ±5% for humidity. The wireless transmission range between the main unit and sensors is up to 100 meters (328 feet).
- Registro máximo e mínimo: The device records maximum and minimum temperature and humidity values for the main unit and all three remote sensors. Data updates every 60 seconds. Users can switch between Celsius and Fahrenheit display modes. The main unit also includes time, alarm clock, calendar, and snooze/light functions.
- Tela LCD transparente: The LCD screen provides clear readability. A humidity comfort indicator uses smiley icons to represent environmental conditions: 'DRY' for humidity below 45%, 'COMFORT' for humidity between 45% and 65%, and 'WET' for humidity above 65%.
- Função de luz de fundo: The display features a backlight for enhanced visibility in low-light conditions. Pressing the backlight button activates the illumination, which automatically turns off after 5 seconds.
- Fácil de operar: The main unit can be placed on a surface using its integrated stand or mounted on a wall. Each remote sensor also supports wall mounting or standing. The main unit requires 3 AAA batteries, and each sensor requires 2 AAA batteries (batteries not included). A low battery indicator will appear on the display when sensor batteries need replacement.

4. Configuração
4.1 Instalação da bateria
- Unidade principal: Abra o compartimento das pilhas na parte traseira da unidade principal. Insira 3 pilhas AAA, certificando-se da polaridade correta (+/-). Feche o compartimento.
- Sensores Remotos: Open the battery compartment on the back of each remote sensor. Insert 2 AAA batteries into each sensor, observing correct polarity. Close the compartments.
Observação: as pilhas não estão incluídas e devem ser adquiridas separadamente.
4.2 Emparelhamento de sensores
After battery installation, the main unit will automatically begin searching for sensor signals. The receiving icon on the main unit will flash. To pair the sensors:
- Ensure all sensors have batteries installed and are powered on.
- The main unit will attempt to connect to the sensors for approximately 3 minutes.
- If a sensor does not connect automatically, press the 'CHANNEL' button on the main unit to cycle through channels until the desired sensor's data appears.
- For manual re-pairing, press and hold the 'CHANNEL' button on the main unit until the receiving icon flashes again, then press the 'TX' button inside the battery compartment of the remote sensor you wish to pair.
