استكشاف الأخطاء وإصلاحها
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| لا يصدر صوت من جهاز الاستقبال | Transmitter or receiver not powered on; incorrect channel selection; low battery; audio cable disconnected. | Ensure both units are powered on. Verify transmitter and receiver are on the same channel. Check battery level. Confirm audio cables are securely connected to mixer/PA. |
| تداخل أو تشويش | Other wireless devices on the same frequency; receiver too far from transmitter; obstacles blocking signal. | Select a different channel on the receiver and transmitter. Reduce distance between units. Ensure line of sight between transmitter and receiver antennas. Avoid placing near Wi-Fi routers or other RF sources. |
| مستوى صوت منخفض | Receiver volume too low; microphone positioned too far from source. | Increase receiver volume. Reposition lavalier microphone closer to the speaker's mouth. |
| CLIP indicator constantly lit | Input signal too strong, causing distortion. | Reduce the input gain on your mixer/PA system or speak further from the microphone. |
| Transmitter battery drains quickly | Old or low-quality batteries; frequent use. | Use fresh, high-quality alkaline batteries or fully charged rechargeable batteries. Consider having spare batteries on hand. |
