Remove the top cover.

1.Disconnect the cable (B).

2.Remove the screws (S).

3.Gently pull the front panel a little to give enough room.

4.Lift out the board.

To refit the board, reverse the above procedure. If you are replacing Front End Board M1353-69512 with M1350-69517, the transparent plastic cover above the CPU board will not fit. This cover is no longer necessary. You may discard it.

Note— Before tightening the screws to secure the Front End Board, slide the board

as far as possible toward the front of the unit. This ensures that the connectors are in their correct positions.
