So the clock is much more elaborate than comparable Braun alarm clock, because the buttons are separated, the red turns on the alarm and made the right next actuates the light and snooze function, the red button protrudes the alarm is activated and is visible on the display , pressed the alarm is disabled and instead the alarm date will be displayed. The only thing I would like to see more would be a quieter slowly increasing alarm. Otherwise perfect. The light can be activated on the battery compartment and adapts to the lighting conditions.
