Uniden BC296D - Manual (Page 48)

1:CTCSS
Continuous Tone Coded Squelch System (CTCSS) is
used with Amateur Radio, FRS, GMRS, Business
Band, and other systems. When you select this
option, the scanner only opens squelch when a
matching CTCSS tone is present on the frequency.
2:DCS
Digital Coded Squelch is similar to CTCSS, but
instead of differentiating codes using frequencies,
DCS always uses the same frequency but encodes it
with a binary value. When you select this option, the
scanner only opens squelch when a matching DCS
value is present on the frequency.
3:OFF
The scanner opens squelch regardless of the
presence of tones.
Note: If, instead of pressing E to select a tone you press L/O,
the scanner will stop on any transmission except for
those with the selected tone.
