transmitter.
Note: The new address is available immediately after it is accepted at
this point, and the unit will respond to only this address when
queried even though you are still inside the main menu tree. If
you abort the main menu tree (see below) then the address will
revert to the previous address.
Maximum: 256
Note: If the B4000 protocol was selected (above), all
communications addresses higher than 16 will be folded back to
address 16.
