Insert the IC socket into
the PC board with the
notch in the direction
shown on the top legend.
Solder the IC socket into
place. Insert the IC into
the socket with the notch
in the same direction as
the notch on the socket.

Electrolytic capacitors have
polarity. Mount the capacitor
with the positive lead in the hole
marked (+) on the PC board.
Warning: If the capacitor is
connected with incorrect polarity
it may heat up and either leak or
cause the capacitor to explode.
