CAUTION
If
any
of these assemblies needs
calibration
or
If
any
non-field
replaceable part
needs
repair,
order
a
replacement
using the
Module Exchange
Program.
To
order
a
replacement module,
use the part number
for the assembly
shown
in the List
of
Parts
and
specify
a
Module Exchange
part.
Table 4D-1 shows
a
list
of replaceable
assemblies.
To
order
any
new
assembly,
refer to
Section
5 for the part
number,
(New
assemblies are ordered by
referring to
the
same
part number). Note
that
two
versions of
the Synthesizer
assembly
are available,
one
with the
Low-Rate
FM
option
and one
without the option.
The
following paragraphs
describe the available exchange
modules,
how
to
install
them,
and
how
to adjust the
Generator,
if
necessary,
after installation.

and
a

4D-5.
Synthesizer
PCA, A2A1
Under
the
Module Exchange Program
there are
two
versions of the
A2A1
Synthesizer
assembly
available.
One
has
the
Low-Rate
FM
option
installed
on
the Synthesizer
PCA
and
the other does
not. Therefore,
when
ordering a replacement
Synthesizer
module
be
sure to specify
whether or
not the Generator
being repaired has the
Low-Rate
FM
option.
Also, before replacing the Synthesizer
PCA
it is
important
to note
what
other options
are
in
the
Generator and
carry
out the following
instructions pertaining to the
option
complement
of
the
Generator,
If the
Low-Rate
FM
option
is
present, verify that S
I
on
the
PCB
option
is
set for
Low-Rate
operation. (See Section
6.)
4D-2
After
the
new
Synthesizer
PCA
has been
installed,
perform
the
FM
CAL,
VCO
CLAMP,
and
10-MHZ
adjustments
as
described
in the Synthesizer
Adjustment Procedure
in
Section
4C
of
this
manual. Perform any
other
adjustments
related to the options.
