Greetings!

Actually, I did something a bit low tech. I printed out a "quick reference" of the PIN numbers to various mixes, sized to fit over the English / Japanese label on the back. I then took some packing tape, attaching the note to the back of the remote. I rigged the tape to have a point toward the front, so I can very easily find it in the dark. In the light, it is a handy reference. When I want to change PINs, I just swap the label.
