3. Preme o SET button to confirm each setting and move to the next.
4. The clock will exit setting mode automatically after a few seconds of inactivity or by pressing SET repetidamente ata que se confirmen todos os axustes.

4.3 Visualización da temperatura (°C/°F)

The clock displays both indoor and outdoor temperatures. To switch between Celsius (°C) and Fahrenheit (°F):

• Preme o DOWN/WAVE/°C/°F button to toggle the temperature unit.

Formato 4.4 12/24 horas

Para cambiar entre os formatos de hora de 12 horas e 24 horas:
