- Sæt batterirummets dæksel på igen.

This image shows the open battery compartment with two AA batteries correctly inserted, indicating the positive and negative terminals.
4.2 Initial Power On and Radio Wave Reception
After battery installation, the clock will automatically attempt to receive radio waves to set the correct time. This process may take several minutes. Ensure the clock is placed in an area with good reception, away from electronic devices that may cause interference.

This diagram illustrates how radio-controlled clocks receive standard time signals from two transmission stations (one in Fukushima, 40kHz, and one in Fukuoka/Saga, 60kHz) to automatically correct and display the precise time. The clock will automatically adjust its time based on these signals.
If reception is successful, the time will be set automatically. If not, you may need to manually set the time (refer to Section 5.1).
