5. Nastavitev
5.1 Namestitev baterije
- Odprite pokrov predalčka za baterije na zadnji strani ure.
- Insert 3 C batteries, ensuring correct polarity (+ and -).
- Zaprite pokrov prostora za baterije.
5.2 Initial Synchronization and Settings
Upon battery installation, the clock will automatically attempt to synchronize with the NIST atomic clock signal. This process may take several minutes to several hours, depending on your location and signal strength. The atomic feature only functions in North America.
- Izbira časovnega pasu: Use the Time Zone switch on the back of the clock to select your local time zone (AST, CST, EST, MST, NST, PST).
- Poletni čas (DST): Set the DST switch to ON or OFF according to your region's DST observance.
- Enota za temperaturo: Select Celsius or Fahrenheit using the dedicated switch.
- Umestitev: Za optimalen sprejem signala postavite uro blizu okna in stran od elektronskih naprav, ki lahko povzročajo motnje.
5.3 Možnosti namestitve
The clock can be wall-mounted or placed on a flat surface using its built-in stand.
- Stenski nosilec: Use the keyhole slot on the back of the clock to hang it securely on a screw or nail.
- Namizno stojalo: Extend the built-in stand from the back of the clock for desktop or shelf placement.

6. Upravljanje ure
6.1 Automatic Time Synchronization
The clock automatically receives the atomic time signal from NIST's Colorado Atomic Clock. This ensures accurate timekeeping without manual adjustment. The signal icon on the display indicates reception status.
- A solid signal icon indicates successful synchronization.
- A flashing icon indicates the clock is attempting to receive the signal.
6.2 Manual Time and Date Adjustment
In areas where the atomic signal is weak or unavailable, you can manually set the time and date.
- Locate the manual set buttons on the rear panel.
- Press the 'SET' button to enter setting mode.
- Z gumboma '+' ali '-' prilagodite utripajočo vrednost (npr. uro, minuto, leto, mesec, dan).
- Press 'SET' again to confirm and move to the next setting.
- Exit setting mode by not pressing any button for a few seconds, or by cycling through all settings.
6.3 Načini prikaza
- 12/24-urni format: The clock supports both 12-hour (with AM/PM) and 24-hour time displays. This setting can typically be toggled via a button on the rear panel or during manual setup.
- Prikaz temperature: Switch between Celsius (°C) and Fahrenheit (°F) using the dedicated switch on the back.
7. Vzdrževanje
7.1 Čiščenje
To clean the clock, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the display or casing.
7.2 Zamenjava baterije
The clock features a low battery indicator. When this indicator appears, replace all 3 C batteries with new ones to ensure continued accurate operation.
8. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Clock not synchronizing with atomic signal. | Weak signal due to location, interference, or distance from transmitter. | Relocate the clock near a window or in a different room. Ensure it is away from electronic devices (TVs, computers, microwaves). Allow up to 24 hours for synchronization. |
| Prikazan je napačen čas ali datum. | Incorrect time zone setting, DST setting, or failed atomic synchronization. | Verify time zone and DST settings. If atomic sync fails, manually set the time and date. |
| Zaslon je zatemnjen ali prazen. | Prazne ali izpraznjene baterije. | Replace all 3 C batteries with new ones. |
| Odčitek temperature se zdi netočen. | Clock exposed to direct sunlight or heat source. | Premaknite uro na mesto s stabilno temperaturo okolice. |
