Solução de problemas
| Problema | Possível causa | Solução |
|---|---|---|
| Sem imagem ou imagem fraca | Baterias descarregadas ou fracas; polaridade incorreta da bateria. | Substitua as pilhas por novas pilhas alcalinas AA, certificando-se da polaridade correta. |
| Clock does not synchronize with R-Wave signal | Poor signal reception due to location or interference. | Relocate the clock closer to a window or away from interfering electronics. Allow several hours for synchronization. Manually set time if necessary. |
| Incorrect time or date after synchronization attempt | Temporary signal disruption; time zone not set correctly. | Allow more time for re-synchronization. Ensure the correct time zone is selected (if applicable, refer to manual setting). Press the RECEBER button to force a signal search. |
| Temperature/Humidity readings seem inaccurate | Unit not acclimated to room; sensor obstruction. | Allow the clock to sit in its desired location for at least 30 minutes to acclimate. Ensure sensors are not blocked. |
| O alarme não soa | Alarm not activated; alarm volume too low (if adjustable). | Ensure the alarm icon is visible on the display. Check if there's a volume setting (though typically not on this model). |
If problems persist, try performing a full reset by pressing the REINICIAR button on the back of the unit using a pointed object (like a paperclip). This will clear all settings and initiate a new R-Wave search.
