ASSEMBLE COMPONENENTS TO THE PC BOARD
Put the three dimples in place with the
concave side faces the copper side of the
PC board. The dimples’ three corners
should all touch the surrounding pad, not
the middle pad of the copper leading to
the middle pad. Hold dimples in place
using a piece of Scotch
® tape as shown.
Final Assembly
1. Place the three plastic dimple caps into position in the case.
2. Push the speaker into the circle inlay
and place the plastic bag over the
speaker.
3. Place the PC board over the speaker.
The end of the speaker will come
through the hole in the PC board.
4. Snap the case together.
5. Attach the battery snap to a fresh 9-volt battery and insert it into the case. Slide
the battery compartment lid into place.

μF Lytic Capacitor
SP - Speaker
Cut two 2” wires and strip 1/4”
of insulation off of both ends.
Solder a wire to each lug of the
speaker. Insert the other ends
of the wires to the PC board in
the holes marked SP. Solder
and cut off the excess leads.
Cut Plastic Parts Bag
1. Cut one of the plastic parts bags to 2” x 3” size.
2. Fold the bag in half, then fold it again in half.
3. Cut 3/8” of the lower right hand corner off as shown.
4. Unfold the bag and you should have a diamond shaped hole in the center.
