When all 4 beam channels of one of the 4 sections are received, the beam-axis
alignment indicator lights up in red. The indicators corresponding to the different
sections light up in red, one by one, when the beam channels of the respective
sections are received. When all beam channels are received and the control output
(OSSD1/2) turns ON, all the four indicators of the beam-axis alignment turn into
green. For information on testing the operation (see page 56).
