If you have the manual and found no listing for Pacific, and also found that a code search doesn't work, then there is no code.

If you don't have a manual, Deal Extreme have a link to one on this page. It doesn't, however, appear to be the same as the one in the set of images and again neither does it, or the one I linked to above, have a listing for Pacific.

I can only suggest you try one or both of these manuals and see if a code search works. Again, if not it's likely there is no code.
