procedure below.
1) Disconnect the Reference Monitor from the mains supply.
2) Remove all the lid screws and take o the lid.
3) Remove the rear blanking plate (4 x M3 x 6 screws).

5) Remove the self tapping screw from the plastic mount on the expansion board and
remove the plate.
6) Place the expansion board plate into the rear of the unit (do not x it yet as it will need
to be loose to aid in the alignment of the expansion board).
7) Plug the expansion board trailing cable into the expansion connector on the main
board.
8) Insert the expansion board into the rear of the unit, putting the BNC connectors
through the loose plate rst.
9) Once in position, screw the expansion plate to the rear of the unit with the 4 x M3 x
6mm screws removed earlier.
10) Fix the expansion board to the plate with the self tap screw into the plastic mount on
the board.
11) Screw the expansion board to the pillar with the M3 x 6 screw supplied.
12) Ret the lid with the 19 o M3 x 8mm countersunk screws. Ensure that all screws are
tted loosely before nally tightening.
