Build the circuit with the base grid centered
on the Rover body, and connect the jumper
wires as shown. TURN THE KNOBS on U9
TO THE LEFT setting. Turn on the slide
switch (S1), the recorded message (if any)
may play.
Push the press switch; a tone is heard for a
few seconds and then shuts off. You can
adjust how long the tone plays for by turning
the upper U9 knob a little to the right. You
can adjust the pitch of the tone by turning
the lower knob on U9 a little to the right.
If the upper U9 knob is set too far to the
right then the sound will seem to stay on
forever. If the lower U9 knob is set too far to
the right then you may not hear any sound.
Turn knobs
to the LEFT
setting.
