Beyond the Basics
using CTCSS and DCS
Your scanner’s advanced, CTCSS and DCS decoder
allows you to listen only to the group that is of interest
to you by specifying the group’s specifi c 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 confi gured 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 display 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 channel 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”.
