Opsætning
1. Batteriinstallation
- Åbn batteridækslet på bagsiden af uret.
- Insert 2 x AA (LR6) batteries, ensuring correct polarity (+ and -).
- Luk batterirummets dæksel forsvarligt.
2. Initial Radio Signal Reception
Upon battery insertion, the clock will automatically attempt to receive the MSF radio time signal. This process may take a few minutes (typically less than 3 minutes). During this time, an antenna symbol will usually appear on the display, indicating it is searching for the signal. Once the signal is received, the clock will automatically set the correct time, date, and adjust for Daylight Saving Time (DST) if applicable.
If the clock does not set itself within a few minutes, try placing it near a window for better signal reception. Radio-controlled clocks can sometimes struggle to pick up signals in certain rooms or locations due to interference or building materials.
3. Radio Control Systems
This clock is designed for the UK and Ireland market, utilizing the MSF signal. For other regions, different radio control systems may be in use.

Billede: Diagram illustrating the two main radio control systems in Europe: MSF for the UK and Ireland (transmitters in Cumbria, UK) and DCF-77 for the rest of Europe (transmitters in Mainflingen, Germany). It advises choosing the correct system for your location.
4. Manual Time/Date Adjustment (if needed)
In rare cases where the radio signal cannot be received, or if you wish to manually adjust certain settings, follow these steps:
- To change 12h/24h display format: Tryk og hold på [Sæt] button until the display shows either '12h' or '24h'. Use the [▲] (Op) eller [▼] (Down) buttons to toggle to your desired setting. Press [Sæt] again to confirm. Continue pressing [Sæt] a few more times until the clock returns to displaying the time.
- Other manual settings (e.g., time zone, specific time/date) may be available by repeatedly pressing the [Sæt] knap. Brug [▲] og [▼] knapper til at justere værdier.

Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Clock does not display time or is incorrect. | Batteries are low or incorrectly inserted. No radio signal received. | Check battery polarity and replace if necessary. Move the clock to a location near a window and allow it to search for the signal. Manually set the time if signal reception remains an issue. |
| Antenna symbol is flashing or not displayed. | Clock is searching for or has lost the radio signal. | Ensure the clock is placed in an optimal location for signal reception (e.g., near a window, away from electronic interference). Allow several minutes for synchronization. |
| Temperatur-/fugtighedsaflæsningerne virker unøjagtige. | Environmental factors or general indication. | The temperature and humidity displays provide general indications and are not calibrated for scientific precision. Ensure the clock is not in direct sunlight or near heat/cold sources. |
| Alarmen lyder ikke. | Alarm is not activated or volume is too low (if adjustable). | Ensure the alarm function is turned on (check for alarm icon on display). This model has a fixed alarm volume. |
