Can't set timer

How do you set the timer without Bluetooth? I don’t have a smartphone.
BTW, the User Guide is worhless.

It’s a kludge. You have to push a button combo on the machine face, then roll the dial to set the timer. And, for all that, all it does is beep at you as it has no advanced features. Better off with an external timer of some sort.
