Notice
Wavetek
maintains
a
continuing program
to
make
improvements
to
their
instruments
that
will
take advantage of the
latest
electronic
developments
in
circuitry
and components.
Due
to the
time
required to
document
and
print instruction manuals,
it
is
not always
possible to incorporate these changes
in
the manual.
Wavetek
has manufactured your
instrument, using metal
film
1%
tolerance
resistors
in
place
of
5%
carbon
resistors,
wherever
practical.
This
results
in
a substantial
improvement
in
the
overall
performance
of your instrument. Therefore, there
may
exist
a
discrepancy between
the
resistor used to
manufacture your instrument and
the resistor
called
out
in
the
Parts List
and Schematic Diagrams
in this
manual.
If
field
replacement
of an affected
resistor
does
become
necessary,
replacement
may
be
made
in
accordance with
the manual
call
outs.
Wavetek, however, recommends
replacement with
the
same
type
of
resistor
used
in
the
manufacture
of your instrument, whenever
possible.
