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 up that will instantly decode 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 found code in the channel memory with one keystroke.
This section of the manual describes the process for configuring a memory channel for CTCSS or DCS
operation and manually programming a known code. For more information on using the CTCSS and DCS
feature while scanning, see “Using CTCSS and DCS” on Page XX.
To program channel memories for CTCSS or DCS operation, follow these steps:
1. First, enter a conventional frequency. See “Storing Conventional Frequencies” on Page XX.
2. Once you have entered the frequency, press MODE until the desired mode appears in the upper left
hand corner of the display. Use CT for CTCSS, and DC for DCS.
3. By default, the search code (indicated with C-Search in the bottom of the display) 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. Note that the scanner will
automatically fill the code field as you enter the code.
4. Once the desired code is selected, press ENT to store the code in the channel memory.
5. It is possible to 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 change, and follow the steps above.
6. When stopped on an active conventional channel while scanning, you can press MODE to cycle through
the valid modes for that channel, including CTCSS and DCS. This will reset any stored CT or DC code to
the search code, allowing you to easily check for other CT or DC codes that may be present on the
frequency.
Note: CTCSS, DCS and digital voice all operate independently of each other. If a channel is configured for
CTCSS or DCS, it will not be able to decode digital transmissions. Use the FM mode when mixed analog
and digital voice reception is desired.
