program code on Russound CA4

I just installed a Russound CA4 into my house. I like to use RCA universal remote controller to control the key pad like volume up/down, power on/off, source1 or 2…selection. I need the program code in order to let remote controller talk to the CA4. Does anyoone successfully programmed a universal controller to talk to Russound amplifier? What is the code I should use?

Thank you so much for your time and help

Or does anyone willing to sell a spare remote controller which can talk to Russound CA4? you can email me at ching01@everestkc.net. Thanks.
