of
this
manual explains
circuit
operation
in detail.
The section
is a troubleshooting
aid when used in conjunction
with the
circuit
diagrams.
Diagrams
A block
diagram
and
detailed
circuit
diagrams are located
on
foldout
pages in the Diagram section.
The circuit
diagrams
show the
component
values
and
assigned
circuit
reference
numbers
of each
component The first
page of the Diagram section
defines
the
circuit
symbols
and
reference
designators
used
in
the manual.
Important
waveforms and voltages
are shown within
the diagrams.
Cirouit Board Illustrations
To identify
electrical
components when troubleshooting,
turn to
the Parts Location Grid that
is located
on the back of a foldout
page
at
the

are
given
in

list.
Component and Wiring
Color
Codes
Colored
strips
or dots on electrical
components signify
electical
values,
tolerances,
etc.,
according
to EIA standards.
Components
not

coded
ususally
have
information
printed
on the body.
Some
wiring coding follow the same EIA standards.
Testing Equipment
A wideband
oscilloscope
plug-ins
and a DVM are required
for
diagnostic
purposes.
