The image shows a yellow-colored electrical panel mounted on a white wall. The panel is rectangular in shape and has a circular hole in the center. Inside the hole, there is a text that reads "Interfono para comunicar con el jefe de vestibulo" which translates to "Interference for communication with the vestibulos" in English. Below the text, there are two buttons - one for entering the text and the other for setting the volume. There is also a small switch on the panel.
