There are two ways you can program your scanner to operate with CTCSS. If you know the CTCSS 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 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 code that is found with the transmission. You can then store the found code in the channel memory with one keystroke.
