Xbee PRO S2 AND S2B communitaion problem [CHANNEL]

Hello,
I have a 2 xbee with XBP24BZ7WIT-004(ZigBee Coordinator AT) and XBP24-BWIT-OO4(ZNet 2.5 outer/End Device AT) MPN (back code). I edited their ID,MY,DH and DL for their communitaion but I could not change their CH. In forums they says Xbee do it automatically but my device cant see each other. There is parameters of devices.

The coordinator selects the channel based off of the channel mask. If you want it to be on a different channel, then change the channel mask (CM) to eliminate the channel you do not want to use.

There is no channel mask(CM) in my properties.

Sorry that is Scan Channel (SC).
