Have you tried contacting the manuf website via the "contact us" link? Perhaps if you explain the situation and maybe even send a pic or a scan of the unit with the numbers that you do have (inside battery compartment) they may help you out.

I had a sandboxed look for some of the links that Welshjim is referring to and any links that may have existed at one time are now dead due to the age of the software (years old).

Also, there are forums that deal with a/v and home theater gear exclusively.. eg- http://www.avsforum.com/avs-vb/index.php perhaps someone at one of those forums would have more ideas.
