Owner`s manual

Birdies are frequencies the scanner uses when it operates. These operating
frequencies might interfere with broadcasts on the same frequencies. If
you program one of these frequencies, you hear only noise on that
frequency.
If the interference is not severe, you might be able to turn SQUELCH
clockwise to cut out the birdie. These are the most common birdies to
watch for:

NOTE: Depending on the temperature of some of the scanner's components,
you might hear birdies on frequencies slightly above or below the
frequencies listed here.
