4 Slowly lower the daughterboard towards the NTRB21, keeping the
standoffs in line with all four holes, until the holes are resting on the
tops of the four standoffs.
If more than a very slight amount of pressure is required at this point,
the connector pins cannot be aligned with the connector socket. If
so, lift the daughterboard off the NTRB21 and return to step 2.
5 Gently apply pressure along the edge of the board where the
connector is located until the standoffs at the two corners adjacent
to the connector snap into a locked position. Then press down on
the two corners on the opposite side until they also lock into place.
