1. Kev faib tawm: cov rooj sib txig ruaj ruaj hlau nplaum rooj sib cais tau muab faib ua phab ntsa mounted hom thiab pem teb mounted yam raws li daim ntawv teeb tsa, hom yas thiab hlau hom raws cov khoom siv; hluav taws xob qhov rooj kaw tau muab faib ua ntau hom. Cov khoom lag luam txhim kho tau muab faib ua peb pawg: hom phab ntsa, hom av thiab saw hom. Raws li cov qauv sib txawv, phab ntsa hom electromagnetic qhov rooj nres tau muab faib ua hom qauv, hom nce siab, hom txuas ntxiv, kem hom, zais hom thiab ntev npab hom.

Qhov av hom electromagnetic qhov rooj stopper yog tsim ntawm phab ntsa hom electromagnetic qhov rooj stopper thiab txoj cai kaum sab xis hauv av mounting bracket; cov saw hom electromagnetic qhov rooj stopper yog tsim ntawm phab ntsa hom electromagnetic qhov rooj stopper thiab cov saw ceev; vim hais tias lub cev lub ntsiab ntawm phab ntsa hom, hom av thiab saw hom electromagnetic qhov rooj nres tau zoo ib yam rau ib leeg, nws yooj yim rau cov neeg siv xaiv xaiv raws li thaj chaw teeb tsa.

2. Cov khoom siv: feem ntau ntawm qhov rooj zoo ua los ntawm cov hlau tsis huv. Lub qhov rooj jams ua los ntawm cov khoom no yog ruaj thiab tsis yooj yim rau deform. Thaum nriav lub qhov rooj stopper khoom, peb yuav tsum them nyiaj tshwj xeeb rau qhov pom thiab cov duab ntawm lub qhov rooj nres, lub thev naus laus zis kev tsim khoom thiab qhov tawv ntawm lub zog poob siab lub caij nplooj ntoo hlav, thiab sim yuav cov khoom lag luam nrog cov qauv zoo, cov thev naus laus zis zoo thiab lub siab poob siab haum tawv.
