Onkyo's website does not give codes for its remote controls. However, these codes appear in the product manuals that come with the remote control devices.
Users can check for the five-digit remote control code at the back of the manual. The codes are set to work with devices from different manufacturers.
Users can also pair the remote with a learning gadget that helps to determine the codes for other manufacturers’ devices. The learning apparatus does not interfere with normal Onkyo functions.
The manual gives directives on how to configure the codes. If more than one code is available for one manufacturer, users enter them one-by-one. The remote indicator flashes twice when the remote code is a match.
