how do i put on the oven on diplomat oven ADP5520, CODICH FIN082, VRSERIE S?

Can anyone please help me to get a copy of a manual for my Diplomat ADP 5520 please. We just moved into the house where the oven was already fitted but no manual. I dont know how to operate the open but everything else is fine. the timer keep bleeping and i had to stop it sometimes but the oven light wont come up. someone came to repair it and said i would need the manual to operate it. please, please help me as my five year old is desperate to bake.
