4. Opsætning
4.1 Batteriinstallation
- Find batteridækslet på bagsiden af uret.
- Fjern dækslet.
- Insert the two AA batteries, ensuring the correct polarity (+ and -).
- Sæt batterirummets dæksel på igen.
4.2 Initial Power-Up and Atomic Signal Reception
Upon battery installation, the clock will automatically power on and begin searching for the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and environmental conditions. During this time, the signal reception indicator (often a wave icon) will flash.
- For optimal signal reception, place the clock near a window, away from electronic devices that may cause interference.
- The clock is designed to receive signals primarily in North America. Signal strength may vary in other regions.
- Once the signal is successfully received, the time and date will automatically set, and the signal indicator will become solid.

5. Betjeningsvejledning
The clock's display provides the following information:
- Tid: Large digits indicate the current time (12-hour format with AM/PM indicator).
- Dato: Måned og dag.
- Ugens dag: Forkortet dagsnavn.
- Temperatur: Indendørstemperatur i Celsius eller Fahrenheit.
- Atomsignalindikator: Shows the status of atomic signal reception.
5.1 Knapfunktioner
The clock typically has buttons on the back for various settings. Common buttons include:
- SÆT: Enters or confirms setting modes.
- KØRSELSVEJLEDNING: Toggles between display modes or setting options.
- WAVE / RCC: Manually initiates atomic signal search.
- TIDSZONE: Selects the desired time zone.
- +/C/F: Adjusts values during setting or switches temperature unit (Celsius/Fahrenheit).
6. Tidszoneindstilling
To set your local time zone:
- Tryk på TIDSZONE button. The current time zone will begin to flash.
- Tryk på + or - button (if available, or MODE/SÆT) to cycle through the available time zones (e.g., PST, MST, CST, EST, AST, NST, HST, AKST).
- Once your desired time zone is displayed, press the SÆT button to confirm. The clock will then adjust to the correct time for that zone after receiving the atomic signal.
7. Manuel tidsindstilling
If the atomic signal is consistently unavailable or if you prefer to set the time manually:
- Tryk og hold på SÆT button for approximately 3-5 seconds until the hour digits begin to flash.
- Brug + or - knappen for at justere timen.
- Trykke SÆT again to move to the minute digits, then adjust with + or -.
- Fortsæt med at trykke SÆT for at gennemgå indstillingerne for år, måned og dag, og justere hver med + or -.
- After setting all desired parameters, press SÆT one last time to exit the manual setting mode.
Note: If the atomic signal is enabled, the clock may attempt to override manual settings once a strong signal is received. To prevent this, you may need to disable the atomic synchronization feature if available (refer to specific button functions on your clock).
8. Vedligeholdelse
8.1 Udskiftning af batteri
When the display dims or the clock stops functioning, it is time to replace the batteries. Follow the battery installation steps in Section 4.1. Always use fresh AA alkaline batteries.
8.2 Rengøring
To clean the clock, use a soft, dry cloth. Do not use abrasive cleaners or chemical solvents, as these may damage the clock's finish or display.
9. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Clock not setting time automatically | Weak or no atomic signal reception. | Relocate the clock near a window, away from electronic interference. Manually initiate signal search using the WAVE/RCC button. Ensure you are within the WWVB signal range (North America). |
| Forkert tid vist | Incorrect time zone selected; temporary signal loss. | Verify the time zone setting (Section 6). Allow time for the clock to re-synchronize with the atomic signal. If persistent, try manual time setting (Section 7). |
| Displayet er svagt eller tomt | Lave eller afladede batterier. | Replace batteries with fresh AA alkaline batteries (Section 8.1). |
| Temperaturaflæsningen er unøjagtig | Clock exposed to direct sunlight or heat source. | Flyt uret til et sted med stabil omgivelsestemperatur. |
