Electrolux premier single builtin oven, model EPSO MMS ?

Have been give this oven , now cannot get it out of Auto mode.I understand you have to hold down 2 buttons to do this but which 2 (there are 4 ) ? When I hold down the first 2 the clock stops flashing so does auto but then I leave it and it starts flashing again,none of the other buttons seem to do anything . Also does anyone have a manual for this oven as I can't find one anywhere :(

Many thanks in advance for any help ,
