Manual

Assembly (adult supervision recommended):
1. Place base grid supports on the base grid labeled A in the drawing.
2. Place parts on grids B & C, and install into base grid supports on grid A.
3. Install remaining parts on grid A.
4. Add the mirror and Q4 attachment.
Turn on the slide switch (S1), and carefully align the mirror so light from
the white LED (D6) reaches the phototransistor (Q4); an alarm will sound
when you succeed. The press switch (S2) is used as a 1-snap wire, so
pressing it has no effect.

The Q4 attachment helps
prevent other lights in the
room from triggering the
phototransistor (Q4), so that
the phototransistor is only
activated by the color LED.
