Hola a todos.
Por el contexto comprendo lo que es: una opción de emergencia que permite que el dispositivo siga funcionando aunque detecte que no se están cumpliendo las condiciones ideales. ¿Cómo se llama?
"Override" aparece en varias ocasiones en otras preguntas de kudoz, pero no creo que puedan aplicarse a este concepto.
Muchas gracias.
