Beyond the Basics

using CTCSS and DCS

Your scanner’s advanced, DSP-based CTCSS and DCS, decoder allows you to listen only to a frequency group that is of interest to you. Simply specify the group’s specific CTCSS or DCS code for a certain frequency. CTCSS and DCS can also help reduce interfering signals that 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 CTCSS or DCS code and the code stored in channel memory. If 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 scanning. If the special “search” code is in use, the scanner instantly displays any detected CTCSS code if programmed for CTCSS mode, or DCS code if programmed for DCS code. You can store the detected code into channel memory by pressing ENT while the code is displayed.
