Wireless autopilot remote control for QK-A031

Hello,

Seems that my RZ610 has linked up to my TV Comcast XR2 remote control. When I turn on the TV with my Comcast remote control, the RZ610 also turns on. How can I prevent this? I would like to turn on the RZ610 only by using the RZ610 remote control. I've tried several different TV codes for the TV Comcast remote, but the RZ610 seems to synch and link back with the TV Comcast remote again, even after the codes have been changed. Is there a setting in the Onkyo RZ610 settings that would prevent it from linking to my Comcast remote control?

Please help.

I did not find the right solution from the internet.
