Xbee pro s1 how to determinate if radio is working

i have two xbees pro s1, they are connecting with x-ctu, i set up MY=1 DL=2 and CE=1 and MY=2 DL=1 and CE=0(rest is default), and i cant see any communication between modules, question is: Is setup wrong or radios are damaged(frequency meter dosent show any value but it is not most accurate)
