Maintenance
Keep
the
scanner dry;
if it
gets
wet, wipe it dry
immediately.
Use
and
store
the
scanner
only in
normal temperature environments. Handle
the
scanner carefully;
do not drop it.
Keep
the
scanner
away
from dust and dirt, and wipe it with a damp
cloth
occasionally
to
keep
it looking new.
Modifying or
tampering
with the
scanner’s
internal
components
can cause a
malfunction and
might
invalidate
its
warranty and
void
your FCC
authorization
to
operate
it.
Birdie
Frequencies
Birdies are operating frequencies, which all
scanners
have,
that
are created inside
the
scanner’s receiver
and
can cause interference. If
the
interference is
not severe,
you adjusting
the
squelch
might omit the
birdie,
but
if
you program one
of
these frequencies after a search,
you
will
hear only noise
on that frequency.
If you suspect
that
a
frequency you have programmed
is
being affected
by
a birdie,
try
removing
the antenna.
Removing
the
antenna
will
help determine
if the
interfering signal
is a
birdie
signal being generated
inside
of the
scanner,
or the
result
of
an external
interference
source. If
the
noise
on
a frequency is
not
affected
when
the
antenna is removed,
it
is almost certainly
the result
of
a birdie. If
the
noise disappears when
the
antenna
is
removed,
the
noise is most likely coming
from
an
external
source. Moving
the
scanner may reduce
or solve the
issue.
