Figure A
Mount the LED
flush to the PC
board with the flat
side of the LED in
the same direction
as marked on the
PC board.
Figure G
Mount the mylar capacitor to the PC
board and bend it 90
O as shown. Solder
and cut off the excess leads.

Figure B
Insert the IC into the PC board
with the notch in the same
direction as marked on the PC
board.
Figure F
Form a discarded piece of a capacitor lead long
enough so 1/4” of wire passes through each hole in
the PC board. Mount the wire down close.
Figure E
Diodes have polarity.
Mount them with the
band in the correct
direction, as shown on
the PC board.

Figure C
Mount the transistor with the flat
side in the same direction marked
on the PC board.
Leave about
1/16” space between the PC board
and the transistor.
Figure D
Electrolytic capacitors have polarity. Be
sure to mount them with the negative (–)
lead (marked on side) in the correct hole.
Mount the electrolytics horizontal to the
PC board. Bend the leads at right angles
and then insert the leads into the PC
board.
J3 & J4 - Battery Snap
Install the red wire into the positive (+) hole
and the black wire into the negative (–)
hole as shown. Bend the leads to hold the
battery snap in place. Solder and cut off
the excess leads.
