Is this your remote? If so,
it's really a "One For All" remote in disguise. It uses
all the same setup codes that an OFA remote would use,
except they're all 17 higher. For example, the normal
OFA code for Panasonic DVD players is DVD/0490, so with
the RCU810 you should try DVD/0507 (ie, 0490 + 17).
