Qhov no disables lub mechanism. Yuav qaib cov shutter kom deb li deb li sai tau (nyiam dua ob los yog peb tus cwj nrag ntawm lub zog). Eliminates qhov no poob ntas rau cov zaj duab xis thaum lub sij hawm raug. Tsis txhob cia lub tshuab nrog lub shutter cocked rau ib ntev lub sij hawm, raws li qhov no tej zaum yuav ua rau ib tug deterioration ntawm nws cov lag luam. Thaum noj cov duab nyob rau hauv frosty huab cua yog tsis pom zoo kom tawm cov khoom tawm sab nraud.
