Have inherited this oven with new apartment, and can't figure out how on earth it works. It's variously branded as "Prima Donna", "Technika", "TriesteTR" and "Eurototech", but nobody seems to have a manual, and I can't find out who the manufacturer is!!!! Feel free to email me on richardxxx@hotmail.com. Need manual fast, as I can only turn the microwave on and off manually with me doing my own timing - and I'm sure it's supposed to be more sophisticate than that !!!
