| No power | Unit not plugged in; power adapter faulty; battery depleted. | Ensure power adapter is securely connected and plugged into a working outlet. Charge the unit if using battery power. Try a different power source or adapter. |
| Cannot communicate with another unit | Different digital codes; different channels; out of range; interference. | Verify all units are set to the same digital code (A, B, or C). Ensure both units are on the same channel. Move closer to the other unit. Change the digital code or channel to avoid interference. |
| Poor sound quality / Static | Interference; weak signal; unit too far apart. | Change the digital code or channel. Reduce the distance between units. Ensure no large obstructions (e.g., thick walls, metal structures) are blocking the signal. |
| VOX not activating | VOX mode not enabled; low voice volume. | Press the VOX button to enable VOX mode (indicator light should be on). Speak louder or closer to the microphone. |
