Hold the Sub PCB firmly with both hands, and
then pull out it from the main board.

Clean the terminal (both adverse and back sides)
of the detached PCB with lint-free paper
impregnated with alcohol.

With the Sub PCB [4] temporarily inserted,
temporarily fix the Sub PCB support plate [5]
with 2 screws. (Leave a space of approx. 1mm
between the seating surface of the screws and the
support plate.)
