3. Grasp the pair of latches (3 in Figure 8-49) near the top and bottom of the
LCB. Simultaneously push the latches to the left, and then pull them out and
away from the LCB.
4. Simultaneously grasp the same pair of latches again, and slowly pull them
toward you. As the LCB begins to slide out of the control module, be sure to
support the LCB from underneath, being careful to touch only the metal cover
and the ground plane.
Important: DO NOT touch any components on the LCB firmware board.
Hold it by the metal cover and support it by the metal ground
plane along the bottom edge.
5. Once the LCB has been removed from the control module, carefully lay it
(Figure 8-50 on page 8-48) on a clean, flat surface.
