Uniden BCT-10 - Manual (Page 17)

3. Turn the SQUELCH conrol back counter clockwise just until
the hiss stops. Now the “Squelch Gate” allows only strong
signals through.
4. Sometimes when you open the Squelch, you may trigger the
Alert feature even though no highway patrol cars are in the
area. If this happens, turn the SQUELCH control
counterclockwise until the “rushing” noise stops. Then turn the
BCT-10 off, and back on, to reset the Alert feature.
Note: In metropolitan areas, you may want to adjust the Squelch
control more counterclockwise to reduce the range of
the Alert feature. When set fully counterclockwise,
Squelch limits the Alert range to a short distance.
