tyt radio

Hey y’all, I’m new to ham radio so I apologize if this is a stupid question. I’m trying to tune into McCormick County fire dispatch on my UV-88, which is 154.725000, but I need to program a PL/CTCSS tone (PL 127.3) into it to be able to hear anything, but my radio didn’t come with a programming...

I have a TYT UVF8D radio and I want to disable Transmit on certain channels but the programming software doesn't seem to allow me to do so, does anyone know how to? Thanks.
