Locking In A Transponder On A 622 at Sat. 61.5?

Hi, The tech set up my 622 on sat. 61.5 on transponder 2 signal 93. It went out in the rain the other night, when the skies cleared I checked out the other transponders and found #14 at a signal of 110. I left it at 14, when I went back in the dish setup the transponder was at #7. How do I lock in at #14? I have 2 500 dishes. Thanks
