CTCSS and DCS

Your PRO-97 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 instances where interfering signals 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 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”.

To program channel memories for CTCSS or DCS operation, follow these steps:

1.First, enter a conventional frequency. See “Storing Known Frequencies into Channels”.

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.
