Automatic Synchronization:

1. After battery installation, the clock will automatically start searching for the MSF signal. A radio wave icon will flash on the display.
2. Place the clock near a window, away from electronic devices that may cause interference.
3. The initial synchronization process may take several minutes to a few hours, depending on your location and signal strength.
4. Once the signal is successfully received, the radio wave icon will appear solid on the display, and the clock will show the correct time and date.
5. The clock will automatically adjust for Daylight Saving Time (DST) and perform daily checks to maintain accuracy.

Manual Signal Search:

If the clock does not synchronize automatically or if you wish to force a signal search, press and hold the WAVE / RCC button. The radio wave icon will flash, indicating it is searching for the signal.

Manual Time Setting (if radio signal is unavailable):

In areas where the radio signal cannot be received, you can manually set the time and date:

1. Press and hold the MODE / SET button until the time digits begin to flash.

3. Press MODE / SET again to confirm the setting and move to the next adjustable item (e.g., minute, year, month, day, 12/24-hour format, temperature unit).
4. Repeat steps 2 and 3 until all settings are configured.
5. Press MODE / SET one last time to exit the setting mode.
