The following procedure will discuss the

removal of the "piggy-back" PCB.

Note: The "piggy-back" PCB does not

need to be removed when removing the

main PCB.

3.1 Perform procedure 1.

3.2 Locate the four plastic stand-offs (three

are located in the corners of the PCB and

one is located between C125 and C225).

3.3 With small needle-nose pliers, squeeze

the retaining tab of each stand-off while

gently lifting up on the PCB to release the

lock. Grasp the PCB at the middle of each

side and lift the PCB off of the connectors.

4. 302EQ ("piggy-back") PCB Replace-
