SPECIAL
ASSEMBLY
NOTES
NOTE:
The
following
suggestions
will
not
necessar-
ily
improve
the
operation
of
your
kit.
They
will,
however,
help
you
troubleshoot
it
(if
it
ever
becomes
necessary),
and
help
you
perform
the
"Circuit
Board
Checkout"
steps
at the
end
of
the
assembly
sections
of this
Manual.
And
you
will
have a
more
profes-
sionally-built
kit
when you
finish.
1.
When
you
install
resistors,
always
position
each
resistor
so
you
can
read
the
bands
on the
resistor
in
the
same
direction
as
you
can
read
the
printing
on
the
circuit
board
(see
Figure
1).
For
resistors
that
have
the
value
printed
on
them
instead
of
color
bands,
install
these
resis-
tors
so
the
values
are
facing
aw^y
from
the
cir-
cuit
board
and
read
in
the
same
direction
as
the
printing
on
the
circuit
board.
3.
When
you
install
electrolytic
or
other
tubular
capacitors,
always
position
each
capacitor so
the
value is
facing
away from
the
circuit
board
(see
Figure 3).
Be sure
to
observe the
correct
polarity
when
you
install
electrolytic
capacitors
(as you
will be
directed in
the
steps).
Other,
non-polarized,
capacitors
should
be
installed so
you
can
read the
values
in the
same
direction
as
the
printing
on the
cir-
cuit
board.

Install
diodes
so

num-

are

Be
sure
to
match
the
band
on
one
end
of
each
rJindfi with the
band
mark
on
the
circuit
board.
2.
When
you
install
ceramic,
Mylar,
or
mica
capacitors,
always
position
each
capacitor
so
you
can
read
the
value
on
the
capacitor
in
the
same
direction
as
you
can
read
the
printing
on
the
circuit
board
(see
Figure 2).
