STEP-BY-STEP PROCEDURE
The following instructions are presented in
a
logical step-by-step sequence to enable
you to
complete your kit with the least possible
con-
fusion. Be sure to read each step all the way
through before beginning the specified operation.
Also read several steps ahead of the actual step
being performed. This will familiarize you with
the relationship of the subsequent operations.
When the step is completed, check it off in the
space provided. This is particularly important
as it may prevent errors or omissions, espe-
cially
if your work is interrupted. Some kit
builders have also found it helpful to mark each
lead in colored pencil on the Pictorial
as it is
added.
The fold -out diagrams in this manual
may be
removed and attached to the wall above
your
working area; but, because they are an integral
part of the instructions, they should be returned
to
the
manual after
the
kit
is completed.
In
general,
the illustrations
in this manual
correspond to the actual configuration of the
kit; however, in some instances the illustra-
tions may be slightly distorted to facilitate
clearly showing all of the parts.
The abbreviation "NS" indicates that a con-
nection should not be soldered yet as other
wires will be added. When the last wire is
installed, the terminal should be soldered and
the abbreviation "S" is used to indicate this. Note
that a number will appear after each solder
instruction. This number indicates the number of
leads that are supposed to be connected to the
terminal in point before
it
is soldered. For
example,
if the instruction reads, "Connect a
lead to lug 1 (S-2)," it will be understood that
there will be two leads connectedto the terminal
at the time it is soldered. (In cases where a lead
passes through a terminal or lug and then con-
nects to another point, it will count as two leads,
one
entering and one leaving the terminal.)
The steps directing the installation of resistors
include color codes to help identify the parts.
Also, if a part is identified by a letter -number
designation on the Schematic, its designation
will appear in the construction step which directs
its installation.
