Was surprised that my old remote control - Dabei to receiver purchase no longer really wanted. Covered the batteries are empty ... with new it was also a moment and then the same problem> no reaction after 5 times zapping After Internet research turned out, I am not an isolated case. the remote control seems to hold only 1 -2 years. For me 1.5. So had her ne new. And now everything is working again and the batteries need declined :) Even such a technique is not ... therefore 1 star less.
