You’ll note an unusual order to the buttons below. If you follow that order, then you
install the outside corner buttons first. That makes it easy to correctly install the rest of
the buttons.
Here’s a good way to install the push buttons. Set SW1, SW11, SW2, and SW7 in the
marked silk screen areas. Place a piece of cardboard over the switches to make a
cardboard-switch-PCB sandwich. Flip the sandwich smoothly and set it on your work
surface. The switches will still be retained, and should be flat against the PCB before you
solder them in place.

button switches are the same, being

IR Detector
Use C2 (not yet installed, 2200 pF film capacitor marked 2n2K63) as a guide to forming
the bend in the leads as shown in Figure 26. This places the center of the bent leads about
0.1” from the edge of the IR detector body.
