How to turn on a Neb Vicenza Oven (manual)

Hi,

We currently rent a house and our landlord has lost the manual to the oven and we can’t seem to turn it back on. Whenever we have a powercut or the oven is switched off we usually just press all the buttons to get it to come back on but for some reason it’s just not working this time.

I was wondering if anyone could possibly tell me were to get a manual from? Or at least tell us which buttons need to be pressed.

Sorry if this seems like a dumb question.

EDIT – Just to clarify the ‘pressing all the buttons’ we’d set the dials to the oven, turn up the heat but it wont come on. Usually we’d press the buttons under the time and it would eventually come back on but this time it wont
