Behind each UB 1-6 (Axing Multiswitch), there is a UB frequency stored that can and must be changed at the receiver. The UB frequency can only be altered at the receiver. The User Band ID is solely responsible for activation in the multiswitch. The program selected by the receiver is then transmitted on the corresponding UB. If the socket and receiver are tuned to the same UB, the program will be received on the TV set. If the UBs in the receiver and the socket do not match, there will be no reception.

If the antenna socket is programmed with UB1, only UB1 will be passed through at the socket. The remaining UBs will be blocked. To ensure a safe and conflict-free installation for apartment and floor-crossing main lines, it is essential that the antenna sockets are programmed.
