This is taken directly from the Olevia website. None of them happen to work for my older 4 digit remote, but maybe you'll get lucky. I'm thinking that the 1610 code would work for me, but it isn't recognized by my remote, and I don't want to pay for a cable to upgrade the software so will suffer with two remotes for now -
