What code do I use with my Cable/Satellite/TV/Universal remote to control my Yamaha receiver or has limited functionality. 

When programming an aftermarket Cable/Satellite/TV or Universal type remote control to work with your Yamaha product.  Please see the documentation for that remote control regarding the Yamaha codes. 

Yamaha cannot provide codes for other manufactures remotes.  When the remote manufacturer created that remote, they programmed in all of the individual code commands for each button and assign them a number/code.  Manufacturers of the actual devices (such as Yamaha) do not control what numbers these remote manufacturers assign to use for our products.

FYI:  Most Cable/Satellite/TV remotes are not re-programmable, meaning that their internal code libraries cannot be updated. The list that is published in the owner's manual for your remote is probably the only codes available for your particular remote.
