I assume you already emailed Tamara the information that those setup codes are in many OFA models (including the Wal-Mart bargain one 6012w), so it should be no problem to find a compatible remote even without JP1.

Also I notice this device does not use the Pioneer IR signals. I'm sure Edmund (and others in other threads) had good evidence to support the guess that an Optimus audio device would be a relabeled Pioneer. But this one adds support to Daniel's view (quoted above) that it could be anything.
