Using CTCSS and DCS
Your scanner’s CTCSS and DCS decoder allows you to listen only to the group
that is of interest to you by specifying the group’s specific CTCSS or DCS code
for a certain frequency. CTCSS and DCS can also help reduce instances where
interfering signals cause your scanner to stop on one channel.
When your scanner stops on a conventional frequency that is configured for
CTCSS or DCS, it checks for a match between the transmitted and stored
codes match, the scanner stops on the transmission and allows the audio to
pass to the speaker. If the codes do not match, the scanner resumes scan
operation. If the special “search” code is in use, the scanner will instantly dis-
play any detected CTCSS code if programmed for CTCSS mode, or DCS code
if programmed for DCS code. You can store the detected code into the chan-
nel memory by pressing ENT while the code is displayed.
For more information about your scanner’s receive modes, including CTCSS
and DCS, see “Understanding Your Scanner’s Modes”. For more information
on programming memory channels for CTCSS or DCS operation, see “CTCSS
and DCS”.
