CTCSS, DCS AND SILENT MODE
CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Coded Squelch)
are similar squelch quieting systems that allow groups of users to share the
same channel without disturbing each other. The CTCSS system uses 1 of 50 low
frequency tones to open and close the squelch on the radio. The DCS system is
similar to CTCSS but uses 1 of 104 digital codes to control the squelch.
When CTCSS or DCS is enabled on your radio, only signals that are using the same
tone or code as your radio will be heard in the speaker and the squelch will remain
closed to all other signals.
Note: CTCSS and DCS codes do not prevent others from hearing your transmission.
