Mozesz podac w ktorym miejscu? jak do tego menu dojsc?
Antena jest sprawna bo jak lezy na desce to złapie sygnał. Juz dwie takie sa, trzecia była rzeczywiscie niesprawna bo miała ułamany rdzen od cewki

We now understand how radio controlled clock synch procedure works. It was tested on my cluster from Audi 2002 D2 FL, software version D39 (your software can work differently).
This is what I calculated with a bit of trial and error:
* Cluster will make a synch sessions with DCF77 at 3am, 4am and 5am every day.
* Synch attempt will only start when ignition is off and cluster displays went to sleep mode by timeout.
* Each synch session lasts about 10-11 minutes. Cluster switches on receiver power only for the length of the synch session. Receiver power stays off all other time. Because it takes 1 full minute to get date and time information from DCF77 transmitter there are 9 or 10 opportunities/attempts to receive full good signal during each synch session.
* During synch session once the good signal is received, say from 2nd attempt, the synch session is prematurely terminated, cluster switches off receiver power, switches itself to radio controlled clock mode, displays antenna symbol, displays correct date and time and makes no further synch sessions during this day.
* If all synch sessions at 3am, 4am and 5am ended with failure cluster makes additional synch sessions after each trip. Definition of trip from cluster point of view: ignition goes on, then cluster receives some speed signal, ignition goes off, key is removed and cluster displays go to sleep mode by timeout. Immediately after that synch session starts.
* If all synch sessions ended with failure for the last 3 days cluster goes back to normal quartz clock mode.
* If cluster's power is switched off (remove fuse number 4 from yellow bank for couple of seconds and put it back) the cluster will forget radio controlled mode and will also forget about time shift from CET time to UK time.
Now, with all this in mind, we have a **quick** procedure to test how well your receiver is working in it's current location:
- If cluster is already in radio controlled clock mode remove fuse number 4 from yellow bank for couple of seconds and put it back. This will save waiting 3 days
