The copy sent me supplied already started unpacking with beeping, even though the battery was not yet activated! Great if - like me - at night happens in a small apartment! Off not going. Also destroy not, because of the guarantee. So I have this thing quickly carried into the basement and there stored in the refrigerator wrapped thick. The next day on the fridge all gelauscht- still. When I went out to grab him again (battery was disabled!), He again began to peep! Today I unpacked it again. He beeped not only flashed. Fortunately, the manufacturer has printed a phone number to the operating instructions and takes the issue seriously - this is the positive side of the device.
