Kusashanda kuri nyorekurapwa
| malfunction zviratidzo | Kusashanda zvakanakachikonzero |
| Hapana chinoratidza pane inogamuchira uye transmitter | Hapana simba pane transmitter, inogamuchira simba haina kubatana nemazvo |
| Iyo inogamuchira haina RF chiratidzo | Iyo inogamuchira uye transmitter frequency mabhendi akasiyana kana kunze kweiyo inogamuchirwa renji |
| Pane redhiyo frequency chiratidzo, asi hapana odhiyo chiratidzo | Iyo yekuparadzira maikorofoni haina kubatana kana iyo inogamuchira squelch zvakarekudzika |
| Inzwi rekutungamira redunhu kusashanda | |
| Kugadzirisa silent mode | |
| Ruzha rwekumashure rwakakurisa | Transmit modulation frequency deviation idiki zvakanyanya, gamuchira kubuda kwemagetsi Level yakaderera, Kana pane chiratidzo chekuvhiringidza |
| Audio chiratidzo kukanganisa | Transmittermodulation frequency deviation zvakarehombe, receiver output yemagetsi Level yakakurisa |
| Kushandiswa kureba kupfupi, chiratidzo hachina kugadzikana | Iyo transmitter yekumisikidza simba yakadzikira, uye inogamuchira squelch yakadzika zvakanyanya. Kugadzika kwakashata kweantenna inogamuchira uye kupindira kwakasimba kwebhatiri kwakatenderedza. |
