Step 4: Install two op-amps, and one echo audio processor

The op-amps and echo audio processor have to be oriented correctly
in order to function properly. There are two indicators to guide you
in positioning it:

The op-amps have a dot molded into the corner of the top side. The
locations on the circuit board have a solid rectangle marked inside
the outlines for the components. The molded dot on the op-amps
need to be oriented in the same direction as the solid rectangle.

The echo audio processor has a small divot on one end. This should be
oriented with the solid rectangle in its location on the circuit board.

Step 5: Install one linear voltage regulator

The linear voltage regulator is directional, and needs to be installed
in a specific orientation. Note that it has a flat side. On the circuit
board, its location outline also has a flat side, install the transistor to
match this outline.
