4.1 Atomic Time Synchronization (WWVB)
The clock automatically synchronizes with the WWVB radio broadcast from Fort Collins, Colorado, ensuring accurate time. This process typically occurs overnight. For best reception, place the clock near a window and away from electronic interference.

Image 4.1: The atomic clock automatically corrects its time daily by receiving the WWVB signal, covering eight time zones and adjusting for Daylight Saving Time.
4.2 Ručno podešavanje vremena i datuma
In areas where the WWVB signal is weak or unavailable, you can manually set the time and date:
- Pritisnite i držite SET dugme za ulazak u režim podešavanja vremena.
- Koristite UP or DOLJE tipke za podešavanje trepćuće vrijednosti (npr. sat, minuta, godina, mjesec, dan).
- Pritisnite SET dugme za potvrdu svake postavke i prelazak na sljedeću.
- The clock will exit setting mode automatically after a few seconds of inactivity or by pressing SET repeatedly until all settings are confirmed.
4.3 Temperature Display (°C/°F)
The clock displays both indoor and outdoor temperatures. To switch between Celsius (°C) and Fahrenheit (°F):
- Pritisnite DOWN/WAVE/°C/°F button to toggle the temperature unit.
4.4 Format 12/24 sata
Za prebacivanje između 12-satnog i 24-satnog formata vremena:
- Pritisnite UP dugme za prebacivanje između 12-satnog (sa indikatorom AM/PM) i 24-satnog formata.
