The Beosystem 4500 that I just got works perfectly, but every night at 21.30 it turns down the lights connected to LC2's. The Beolink 7000 that I got with a recently bought Beosystem 7000, is being repaired by my dealer. Is there any way that I can clear the light programming that is still in the Beomaster 4500 without the Beolink 7000. I have several Beo4's.
