Unfortunately, I don't have a map from the manufacturer and don't see 
one on their website. I've sent them an email just now. Hopefully, 
they'll respond with something useful.

I was hoping to get some report on scancode/keycode and build a custom 
map if necessary.  Is there no utility that allows one to see the actual 
scancodes from the remote? There are 120 maps in the rc_keymaps folder 
and I would like to avoid trying one after another.

Thanks for your assistance!
