I know many folks have tried to help you out, but the language barrier seems to be the problem.
a.) Your friend has an XTS Motorola series radio.
b.) He works for a Law Enforcement Agency that you want to listen to on your scanner.
We need to know what BAND his XTS Radio is programmed in. VHF-Lo, VHF-Hi, UHF, 700, 800, 900 Mhz
are the most common bands.
Then we can point you where to SEARCH
for his frequencies. Sorry, but your country doesn't publish frequencies as freely as the USA, and we have pointed you in the right direction a few times.
Otherwise use the SEARCH button on your scanner and look for local signals/voices/locations being talked about.
if i would like to scan for UHF or VHF-Lo etc.. is it from the scanner or the anntena or what ?
thanks
