□: Rated tam sim no ntawm ncej
□: Rhuav lub peev xwm tus yam ntxwv code / S qhia hom qauv (S tuaj yeem raug tshem tawm) H qhia hom siab dua
Lus Cim: Muaj plaub hom ncej nruab nrab (N ncej) rau plaub theem khoom.Lub nruab nrab ncej ntawm hom A tsis yog nruab nrog dhau-tam sim no tripping caij, nws ib txwm hloov mus rau, thiab nws tsis tau hloov los yog ua ke nrog lwm yam peb ncej.
Cov ncej nruab nrab ntawm hom B tsis tau nruab nrog cov khoom siv tam sim no, thiab nws tau hloov los yog ua ke nrog lwm tus ncej (tus ncej nruab nrab yog hloov mus ua ntej yuav hloov OF) Cov ncej nruab nrab ntawm hom C yog nruab nrog tshaj- tam sim no tripping caij, thiab nws yog switched los yog off ua ke nrog rau lwm yam peb ncej (lub nruab nrab ncej yog switched rau ua ntej yuav switched OF) Lub nruab nrab ncej ntawm hom D yog nruab nrog over-tam sim no tripping caij, nws yog ib txwm switched rau thiab tsis hloov. ntawm los yog ua ke nrog rau lwm yam peb ncej.
