OPERATION
Foil Side of PC Board
Install a 9-volt battery to the battery snap (B1).
Adjust the potentiometer R1 so that the arrow is
turned all of the way counter-clockwise. Adjust the
potentiometers R2 and R3 so that the arrow is turned all of the way clockwise. Hold down the push
button switch and the bird will sing. For varied
sounds, adjust the potentiometers. Be creative, a
variety of sounds can be created!
1. One of the most frequently occurring problems is
poor solder connections.
a) Tug slightly on all parts to make sure that
they are indeed soldered.
b) All solder connections should be shiny.
Resolder any that are not.
c) Solder should flow into a smooth puddle
rather than a round ball. Resolder any
connection that has formed into a ball.
d) Have any solder bridges formed? A solder
bridge may occur if you accidentally touch
an adjacent foil by using too much solder or
by dragging the soldering iron across
adjacent foils. Break the bridge with your
soldering iron.
2. Be sure that all components have been mounted
in their correct places.
a) Make sure that C1-C4, the electrolytic
capacitors, are mounted correctly. The
negative lead should be in the hole as
shown on the top legend.
b) Make sure that U1 has been installed
correctly. The notch of the IC is in the same
direction as the notch on the socket.
c) Pay close attention to the red and black
wires of the battery snap. The red wire
should be installed in the positive (+) hole
and the black wire in the negative (–) hole.
Snap in a fresh 9-volt battery.
