Delivery and Shipping Top! "Installation" and operation easy. Volume up (as requested by Us), sound quality and selection of tunes: Okay, We liked the Tower-tune best. Range with new batteries OK, but after a few weeks reached the station no longer the 3-th farthest bell, which was about 15-20 meters from the transmitter (Intermediate: 1 wooden wall, wooden staircase 1/1 blanket, 1 plasterboard wall ). Since the battery change time is expensive and must be carried out carefully (plastic retaining nipple breaks relatively easy), I have the manufacturer kontaktet and asked if you could not operate the DC power supply the transmitter with a 3-volt. He said basically I do that, however, the guarantee would be removed by the intrusion into the transmitter. I have nevertheless dared and since then everything's fine. The range is now permanently good. Another note: After a power failure or changing the batteries, the bell must briefly pulled out of the plug and be used again. (Initializing, so that the radio contact is re-established.)
