The worst coffee machine interface I ever encountered

One of the most basic tools, a filter coffee maker, normally just needs a on and off switch. Then there is this abomination: it shows you the time, it beeps annoyingly loud when it's turned on or just at random times. It shows a red flashing circle sometimes to indicate god knows what, and it has 4 buttons I don't understand. To be fair: I haven't read the instructions, as this was the coffee machine in my vacation home, but I just can't understand why I would need a manual for something this simple.
