CTCSS AND DCS
CTCSS and DCS allow multiple users to share 
a single radio frequency without hearing each 
other’s transmissions. Your scanner features an 
advanced, DSP-based CTCSS and DCS decoder 
that displays CTCSS or DCS codes when 
available.
CTCSS, DCS, and digital voice 
transmissions operate independently of 
each other. Your scanner will not decode 
digital voice transmissions for CTCSS or 
DCS channels. Use FM mode for mixed 
analog and digital voice transmissions.
To dene a channel’s CTCSS or DCS code:
1.  Press PGM. M changes to P.
2.  Navigate to the channel.
3.  Enter a conventional frequency.
4.  Press MODE until the desired mode (CT or 
DC) appears with the default search code 
value. 
5.  Press FUNC, then MODE. 
6.  Use the  or  to select the desired CTCSS 
or DCS code. 
You can enter the code manually. The 
scanner automatically lls in the code. 
See Appendix B for a list of codes.
6.  Press ENT.
To save a CTCSS or DCS code:
Press ENT while the code appears.
Scanner Cloning
You can transfer the programmed data to and 
from another PRO-164 (or PRO-163) scanner 
using a connecting cable which has 1/8-inch 
stereo (TRS) phone plugs on both ends (not 
supplied). 
You can also upload or download the 
programmed data to or from a PC using an 
optional USB cable and application software 
available through your local RadioShack store.
