μF Electrolytic Capacitor
(see Figure D)
Figure D
Electrolytic capacitors have polarity. Be
sure to mount them with the negative (–)
lead (marked on side) in the correct
hole.
Warning: If the capacitor is connected
with incorrect polarity, it may heat up
and either leak or cause the capacitor to
explode.
Polarity Marking
SPK1 - Speaker
Strip 1/8” of insulation off of both ends of
the 4” wires. Solder a wire to each lug of
the speaker and then insert the other end
of the wires through the hole in the PC
board as shown. Solder the wires in the
position shown on the top legend. Cut off
the excess leads.

Figure A
Mount the LED onto the
PC board with the flat
side of the LED in the
same direction as
marked on the PC board.

Figure B
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.
Figure C
Use an excess lead to form a jumper wire. Bend the
wire to the correct length and mount it to the PC board.
