Position
the
detector circuit
board
as
shown in
the Pictorial.
Then proceed
with
the following
steps.
As you install
each
component
in this
column, solder
its leads
to the foil and
cut off the
excess lead
lengths.
NOTE: When you install diodes,
as in the
following
steps, be sure
you position the
banded end of each diode
as
it is
shown on
the circuit board.
