Your manual requires setting the time, and shows two knobs that you use t5o do this. My Rangemaster 110 does not have knobs--just the six buttons below the flashing "0,00" and "auto" display. I have tried pushing the two pan-shaped symbol buttons, and adjusting with the plus/minus buttons--but nothing happens. Unless I can do this, I can't turn the oven on, either manually or automatically. HELP! Please answer at catnca@aol.com
