this all i can find for 104...
for this you need an aiwa hi fi remote with repeat buttons programme and clock
on the aiwa remote:
first press the repeat button once you have the screen will be a little brighter
then press the programme button.
followed by the clock button several times sometimes quite a few.
then on the player display should appear ADJUST!
get the samsung remote and press which ever region it is you want to play...
the drawer should close automatically now and play the disc...
thats it
