I am programing a RTI T2c and need ir codes for sourse selection, power and volume up and down from a onkyo tx-sr307 receiver. I do have the RtI learning tool but the customer doesnt have the original remote for the unit. i have looked all over and cant seem to find anything online dealing with this recievers ir codes. this is my last resort before i have to buy a new remote for the unit and learn everything in. Please help!!!!
