To remove the A2 CBT Control Assembly
Remove the two multiple pin connectors from the A2 CBT Controller
assembly. These are held in place with sliding locks.
Use the extractor tabs at each end simultaneously to draw the PC
board out of its mating connectors.
Install a new A2 by first aligning the PC board in the slot and then use
only the extractors to press into place. This avoids damaging the
mating connectors.
Ensure that the extractors are flush.
To Remove Any Other PC Boards
Use the extractor tabs at each end simultaneously to draw the PC
board out of its mating connectors.
Install a new PC board by first aligning the PC board in the slot and
then use only the extractors to press into place. This avoids damaging
the mating connectors.
Ensure that the extractors are flush.
