PRV645 timer problem

I am experiencing a problem with a PRV645 recorder. System date gets reset everyday on 10-01-2080 so obviously timer is difficult to use for that matter.
Does anyone know what can be done? (please give technical answers not like take it back to the shop or so …)

Thanks

OK,
I figured out that the recorder gets the time and date from the channel stored on P01 and the channel I had on P01 seemed to fail to “tell” the correct date. I have replaced the programmed channel on P01 with another one (the national TV station :wink: ) and it seems to work.
