In rarely cases the English transmission of the time radio signal (MSF) is stronger (depends on the reception area) and the alarm clock switches to MSF (England) instead of DCF (Germany) automatically.

This event causes the self-acting switch to another time zone and the time difference of one hour.

Please refer to page 13 of the user manual and follow the instructions step by step: Switch the device into normal clock mode. Push and hold the „down arrow button“ a few seconds. Now you can select “DCF” by pushing the same button some times. After selecting DCF you need to push and hold the “down arrow button” again for a few seconds until the transmission signal stopps to blink and the DCF Logo will be displayed permanently.

Then the DCF time radio signal is fixed within the device permanently.

The above mentioned selection should fix the DCF time radio signal within your device.
