How do I replace the oven lamp on the Bbim12300x?

Before replacing the lamp, disconnect the product from the mains and wait for the oven to cool to avoid risk of electric shock and burns. For a round lamp, remove the glass cover by turning it counter-clockwise, then rotate or pull out the old lamp and replace it with a new one before refitting the glass cover. This oven uses an incandescent lamp under 40W or a halogen lamp with G9 socket under 60W, rated for temperatures above 300°C. (Page 34-35)
