After replacing the GAU, attach the two NV-RAMs [A] removed from the old GAU to the new GAU.

The NV-RAM with the label that shows "M-CTL" is attached on the right lower side [A].

The NV-RAM with no label is attached on the left upper side [B].

When attaching the NV-RAM, position the depression [B] of the NV-RAM (M-CTL) to the upper side so that the depression [B] aligns with the concave mark [A] printed in the GAU.

Incorrect attaching may cause both the GAU and the NV-RAM to short-circuit and break.
