How do I make coffee using pre-ground coffee?

Press the strength button (C6) until the ground coffee symbol appears, open the pre-ground coffee funnel lid (A2), and add exactly one level measure using the scoop (D2) — never more than one measure, as this can damage the machine or block the funnel. Only one cup can be made at a time when using pre-ground coffee, and you must never add pre-ground coffee when the machine is off. (Page 11)
