DCF-antenna on
This display serves for switching on and off the DCF-antenna, indicates the last time of
synchronization (third line) and the manual start of synchronization.
When the DCF-antenna is active, it tries to receive a time telegram at night from 01:30 h (max. 10
minutes) because of the better reception. This time telegram is sent during standard time as CET
("Central European Time", CET=UTC+1h), and during daylight saving time as CEST ("Central
European Summer Time", CEST=UTC+2h). This time telegram is converted in UTC, and the
internal clock is synchronized.
In the edit mode the antenna can be activated and deactivated. Additionally in the third line the last
synchronised DCF77-Time is given out:
*DCF: 1
30.04.09 03:33 s
With active DCF-antenna, and sufficient reception, when you wait approx. 2 minutes or longer, the
DCF time telegram is displayed, and the internal clock is synchronized (provided that no error
occurs).
