The backboard must be moved to its in-service position before aligning the
signal as in the transit position; it obscures the holes in the backboard the scope
looks through and the signal will not meet the 300mm backboard criterion
Remove the Lower Backboard Extension from its stowage position above the
aperture by removing the two 3mm Allen screws shown in blue below. Refit the two
screws and dispose of the 2 white plastic labels and the black plastic edge protector
properly.
Using the existing Allen screws shown in green below, mount the plate at the
bottom of the backboard.
