Here is a quick tutorial to use the switchs of your flat properly
Your flat has 2 switchs: one with a "+" and "-", and one all white.
1) To turn on the ring light on your ceiling, press the "+" once. The light will turn on after 2 seconds.
To turn off the ring light, press the "-" once. The light will turn off after 2 seconds.
You can adjust the light intensity of the circle light, by pressing the "+" or "-" continuously.
2) To turn on the neon light on your wall, press the top of the "all white switch" once.
To turn off this light, press the bottom of this switch once.
This switch also controls the plug located near your bed or near your desk: So if you want to use that plug, you will have to turn on that light.
