3. By default, the search code (indicated with Code Search in
the bottom of the display) is programmed. To program
a specifi c 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 fi ll the code fi eld 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.
CTCSS, DCS and digital voice all operate independently

of each other. If a channel is confi gured 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.
