Kuyilo lweigaraji yocango olukude, Isekethe yokulawula ekude ngaphandle kwamacingo kunye ne-Hall sensor isetyenziselwa ukulawula i-motor nge-microcomputer ye-chip eyodwa ukuqonda imisebenzi eyahlukeneyo yocango lwegaraji oluzenzekelayo. Umthombo wesignali yokudlulisa i-infrared, inzwa ifumana umqondiso, kwaye indawo ebuthathaka ijika inkqubo yokulawula. I-motor yecandelo elisebenzayo liqhuba igiya ukuqengqeleka ucango lwe-shutter rolling. Xa ibekwe phantsi, i-motor ibuyela umva. Logama nje imotor kunye ne-drive sprocket, kunye nenxalenye yolawulo.

Ngexesha elifanayo, kukho utshintsho lwe-ultrasonic ngaphakathiiremote yocango lwegaraji. Ngapha koko, icandelo elinye lele-ultrasonic induction. Xa imoto yakho ingena kakuhle kolu luhlu, iya kuchukumisa ukuqhuba.

Iremote yocango lwegarajiikwabandakanya iiswitshi ezimbini eziphezulu nezisezantsi. Xa ukutshintshwa komda osezantsi uchukunyiswe, imeko yayo iya kutshintsha. Iza kuqaliswa ukusuka kwimeko evaliweyo ukuya kwimeko evulekileyo, kwaye umda ophezulu ngumgaqo ofanayo.
