2. Initial Signal Reception
After battery installation, the clock will automatically begin searching for the radio time signal. This clock is designed for the UK and Ireland (MSF signal).
- Place the clock near a window or in an open area to optimize signal reception.
- The signal reception icon (often a tower with waves) on the display will flash during the search.
- Once the signal is successfully received, the clock will automatically set the correct time, date, and day, and the signal icon will become solid. This process may take several minutes.
Note: For optimal signal reception, avoid placing the clock near electronic devices that may cause interference.
