We here indicate the typical overall switching+setup time intervals, so that they correspond to the waiting times the observers actually face.
Secondary focus receivers can be switched between one another, or commanded a new setup, very quickly (10 seconds).
Primary focus receivers switch between one another in a slightly longer time (45 seconds).
The commutation from a primary focus receiver to a secondary focus one, and viceversa, are slower (about 3 min 50 s) because the subreflector must be repositioned - it runs a path exceeding 2 metres.
