A
calibration
table
was
not
loaded
into
EEPROM
because
the
EEPROM
was
protected
or
the
EEPROM
load
did
not
verify
.
Open
up
the
synthesizer
and
switch
the
PG
switch

There
was
an
attempt
to
write
calibration
data
to
ROM.
This
should
not
occur
,
but
if
it
does
,
try
setting the
same synthesizer
function
again.
If
this

The
number
of
EEPROM
writes
has
exceeded
the
maximum
allowed.
However
,
the
data
was written
to
the

This
is
only
a
warning;
but,
you
should
check
to make

your
data
was
correctly
stored
in
EEPROM.

The
YIG
oscillator
factory
calibration
data checksum
was incorrect.
Select
the CAL
YIG
OSC
feature
to
perform
a
YIG
oscillator
calibration.
If
you do
not
re-calibrate
,
the

unable
to
attain
lock
at
some frequencies
.
