Initial Time Setting (DCF Automatic Adjustment)
The clock features DCF automatic time adjustment. Upon initial power-up or after battery replacement, the clock will automatically search for the DCF signal to set the correct time.
- During DCF signal search, the backlight will turn off, and all buttons will be non-functional until synchronization is complete.
- You can press the "WAVE" button to stop the signal search and reactivate all functions.
- For optimal signal reception, place the device near a window and away from electronic interference.
- Note: The automatic time adjustment function (DCF) primarily works within Germany. If you are outside this region, manual time setting may be required.
