Solved! Where can I find orum rohn r509 control codes

Solution
if the manual doesn´t say how, you will need the original remote

you can try a universal remote and try all codes, if the remote itself doesn´t list rohn with codes. Or write a mail to the universal remote manufacturer and ask for the code table or if they can create one for this home theatre system.
