Failure phenomenon after 14 & 18Monaten use.

My positive feedback from some time ago, I regret to revise.
My own device, now almost 14 month old had suddenly advance bezgl Fehlermelungen the Program Change. To weak or no signal. Sometime the error came sporadically without Prgmwechsel. EInzer way was then 5min. compl. De-energize, since there is now no proper OFF buttons more.
The unit of an acquaintance that is now 18monaten old has same problem, but only when Prgmwechsel.
Add. I get to 2h operation, and as the sound you can set the clock to, just go away. A & Off Switch and the prob is gone for the next 2h hours.
Luckily's is' still in the warranty period or in the nice warranty period from Amazon, so you get your money back.
Unfortunately, my "new" replacement unit had been after my 3Tagen beforehand. After 14Mon resulting error.
The big plus for fast booting and program changes I have now unfortunately also move, because after the new software update is all that slow.
Well, there are other manufacturers ... with other quirks ...
