5. Raise the hinged backbox upright and stabilize it into position, using the clamp on the back of the
cabinet and backbox. Unlock the backbox, and remove the back box glass, storing
it
carefully to
avoid scratches. Remove the shipping block holding the Insert Board. Unlatch the Insert Board
and open it, then lay the Speaker/Display Panel forward on the playfield cabinet. This allows
access to the bolt holes used for securing the backbox upright. Install the mounting bolts and flat
washers through the bottom holes of the backbox into the threaded fasteners in the cabinet to
secure the backbox.
6. Reach into the cabinet and backbox and check the mating of the interconnecting cables, match-
ing several wire colors at each connector. Ensure that all connections are properly secure.

Ensure that the interconnecting cables are free to move (not kinked or pinched). Be
careful not to damage wires at any stage of the assembly process.
