that support both analog and
digital modulation. Certain user
groups on these systems may use
analog modulation, while others
use digital modulation. Your
scanner will automatically detect
the type of modulation being used
and switch to the correct
modulation mode without special
programming or user intervention.
Your scanner also features
Intelligent Adaptive Digital
Tracking for optimal reception of
digital signals from a variety of
digital conventional and trunked
radio system types. No special
sound quality settings or
adjustments are needed for
different C4FM system types.
Digital modulation represents a
breakthrough in public safety
communications technology.
Digital modulation typically
provides a clear, distortion free
audio signal throughout the
service area of the system you are
monitoring. However, there are
some important differences
between analog and digital voice
performance that you should be
aware of while scanning.
In most cases, digital voice
transmissions will be surprisingly
crisp and clear, and without noise
or distortion, even when
corresponding analog signals from
the same system contain some
static. However, if you are in a
location with marginal reception,
you may find that the voice quality
of digital signals deteriorates very
rapidly, resulting in missing
syllables or entire words. If this
