Korg Poly800/EX800 Users

Hi. I recently beacame owner of the korg poly800. I have a problem. I
don't have the manual so i don't know how can i save the programs i
make  on it. I have to program my synth for each sound i want to play
every single time i turn it on. I no very little things for my synth
and the biggest problem of all is that when i want to use it i must
sit and program 3-4 sounds for about half an hour. I'm sorry if my
questions sound kind of silly but i'm from Greece and as you can
understand i can't say i have easy access to information related to my
synth. If these questions are already answered in another topic please
tell me the   topic.
Thank you for your time
