Yooj yim malfunctionkev kho
| Cov tsos mob Malfunction | Ua malfunctionkev kom |
| Tsis muaj qhov taw qhia rau txais thiab cov khoom xa tawm | Tsis muaj lub zog rau ntawm transmitter, lub reliver power tsis txuas nrog kom zoo |
| Tus txais nyiaj tsis muaj RF teeb liab | Tus tau txais thiab lub tshuab xa tawm zaus ua ntu zus yog qhov sib txawv lossis tawm ntawm cov khoom siv tau |
| Muaj xov tooj cua tau taw qhia, tab sis tsis muaj lub teeb liab audio | Lub tshuab xa hluav taws xob microphone tsis txuas lossis tus txais kev txais yog ib yam nkaustob |

| Lub suab nrov lub suab keeb kwm yav dhau los yog cov laus heev | Hloov cov kev hloov kho ntau zaus sib txawv me me, tau txais cov zis hluav taws xob qib qis, lossis muaj cov teeb meem cuam tshuam |
| Audio Kos Npe Distortion | Xa xovterKev Hloov Mob Ntau zaus sib txawv yog ib yam nkausLoj, txais cov khoom siv hluav taws xob hluav taws xob hluav taws xob ntau dhau |
| Kev ntsuas kev deb yog luv luv, lub teeb liab tsis ruaj khov | Lub tshuab xa hluav taws xob teeb hluav taws xob yog tsawg, thiab tus tau txais squelch yog qhov tob heev. Kev tsis raug teeb tsa ntawm tus kav hlau txais xov thiab muaj zog roj teeb nyob ib ncig ntawm. |
