How do you reset A30-RF1 - DirecTV

Was programming my A30-RF1 to contol additional devices and suddenly the remote will not control my ATT DVR Reciever. Followed the instructions to 'Change back to RF' as I though I may have somehow 'Changed to IR' but this did not work. Followed the instreuctions to 'Program a Home ID' but the remote still will not control my ATT DVR/Reciever. There are no instructions on the ATT website to reset an A30-RF1. Need to know how to reset an A30-RF1 point anywhere remote. Thank you.
