Have you checked the Remote ID on the receiver?
■ Remote ID
`1, 2, or 3
When several Onkyo components are used in the same
room, their remote ID codes may overlap. To differentiate
the AV receiver from other components, you can change
its remote ID from “1”, to “2” or “3”.
• If you do change the AV receiver’s remote ID, be sure to change
the remote controller to the same ID (see below), otherwise, you
won’t be able to control it with the remote controller.
Changing the remote controller’s ID
1 While holding down RECEIVER, press and hold
down Q SETUP until the remote indicator lights
(about 3 seconds).
2 Use the number buttons to enter ID 1, 2, or 3.
The remote indicator flashes twice
