How do I program my City so I can listen to the Police feed

Hi, So I bought a Uniden Home patrol 1, How do I program my city Police feed? I seen "Livermore Police" on it before now I cant find it even entering the zip code or city, I have the squelch up high as well even tried it low, and I still dont see it, I updated the firmware and did the "write to home patrol" Still Dont see Livermore California ( Alameda County ) Can you please help me, Thank you.. -Perry Email: PerryJayStewart@gmail.com
