Beyond the Basics
programming CTCSS/DCS channels
Your scanner features an advanced, DSP based CTCSS and DCS decoder. CTCSS and DCS allow you to program frequencies into your scanner that are used by more than one group in your area and listen only to the group that is of interest to you by specifying the group’s specific CTCSS or DCS code. CTCSS and DCS can also help reduce interfering signals that cause your scanner to stop on one channel.
There are two ways you can program your scanner to operate with CTCSS and DCS. If you know the CTCSS or DCS code that is used on a particular frequency, you can manually enter the code when you are programming the scanner, or any time afterwards. You can also set a special search code that instantly decodes the CTCSS or DCS code on a received transmission. Channels programmed with the search code will receive all traffic on the channel, and will instantly decode and display any CTCSS or DCS code that is found with the transmission. You can then store the code in channel memory. For more information on using CTCSS and DCS while scanning, see “Using CTCSS and DCS”.
1.Enter a conventional frequency.
2.Press MODE until the desired mode (CT for CTCSS, and DC for DCS) appears on the display.
3.By default, the search code is programmed. To program a specific code, press FUNC, MODE, and then use the arrow keys to scroll to the desired CTCSS or DCS code. You can also use the keypad to enter the code manually.
4.Once the desired code is selected, press ENT to store it in channel memory.
5.You can program memory channels for CTCSS or DCS operation at any time. Simply place the scanner in program mode, navigate to the channel you wish to
