Where did you buy your L336 remote? If you bought it from VGP it should be preprogrammed for usage with the OSSC and should work right out of the box. If you bought a “blank” one from anywhere else, you’ll need to program it by yourself. But there aren’t any codes to put directly into the remote. You HAVE to have a remote (or an IR transmitter which is able to act as a remote) the L336 can learn from.
