To activate and deactivate the dark mode in Missionchief you just need to go to the settings tab in any of your dispatch centres, scroll down right to the bottom to the “Design” section. For the dark mode select “Dark” or “Window Design - Dark”.

Many people prefer using dark mode with a black background because it is better for the eyes and you can significantly save energy by using the dark mode, so you won’t have to charge your device as often.
