There is a corresponding footprint for the
socket, at location U1 on the circuit board.
It has a corresponding notch at one end.
Flip the circuit board over, while keeping
the socket in place.
Insert the socket into the circuit board,
matching the two ends with the notches.
This is
#6
, the 40-position socket for the
microcontroller. Locate the polarity
marking notch at one end of the socket.

To ensure good positioning, rest the
circuit board
fl
at on top of the socket.
The socket pins will protrude (but only
very slightly) through the circuit board
