Error
lndications
Sometimes
when
you
try to
enter a
frequency for
a channel or as a
Search
range
limit,
you
will
find an
error on
the
display.
This means
the frequency is in error and
you
won't
be able
Io
enter it into
your
PRO-30.
Such
frequency errors usually mean
you've
entered a
frequency
outside the
ranges
your
PRO-30
operates
on
(such
as 225.00 MHz)
or
you've put
the decimal
point
in the wrong
place
(14.682
MHz
instead of 146.82 MHz). Check carefully to find
your
mistake and
then
press
IEA-RI.
You
can now enter the correct frequency.
Birdies
Some
frequencies
may
be
difficult
or impossible
to receive. lf
you
program-in
one
of these, the
Scanner
might
lock up
and
you'll
hear
only noise. These
"birdies"
are the
products
of internally
generated
signals mixing with
external signals
like
TV
and
FM
broadcasts.
lf the interference
is not severe,,
you
might
be able to use
SOUELCH
to cut out
such annoying birdies.
