Notes on assembling
You should insert the connector straight
and all the way in. Be careful when
handling the reading unit connector
because it is thin.
Furthermore, although the lengths of the
upper and lower cables of the reading
unit differ to suit the positions of the
connectors, the connectors are the
same, and you should not connect them
incorrectly.
