Blue-Wave 5 in one timer

I've just bought the Blue-Wave 5 in one mug press. And I have been able to set the temperature and timer. But for the life of me I can't work out how to set the timer off when the temperature is reached. There is no separate timer button. I'm pretty sure I'm missing something obvious. Anyone help me out here?

OK - it's the enter button

Not helpful to your question, but I had this machine and I couldn't get sharp results, so ended up buying an oven and the press has been sitting under my table ever since.
