on
the board
in
the lower left hand
quarter of the board. The
Sound Block A board is plugged into this
connector and mounting hardware is
rinstalled to secure it.
How
to
know if the
CGP
board is ready for the addition of the
Sound
Block'
A board? Check
in
the vicinity
of
the long white
connecter (47A)
located
in
the lower left· hand quarter
of
the CGP
board. If this board has been modified to accept a Sound Block A
board, you
will notice some rework wiring coming from U126, U134
and U149,
to
name a few. This wiring will begin at these locations
and encircle the white connector and end at locations below.
