Flipper Remote and Infra Red settings

[2shoes]

I bought a Flipper Remote V7 (large buttons) for my elderly mother who has a hard time using the Comcast remote. 

I am trying to get the Flipper to work with Xfinity cable box  model # XG2-v2-P.  Flipper support says I need to change the Xfinity from RF to IR. (infra red) to make the remote work.  Is this even possible?  I can't find anything in the settings.  If anyone has any help, I'd appreciate it.  

Thanks

On the X1 remote press and hold setup, LED goes from red to green and press 987

Thanks.  Changed it to IR, still can't get there Flippin remote to work.  How do I change it back to RF?
