| Fault Symptom | Troubleshooting Steps | Resolution |
| No output signal | 1.Check power supply voltage/ current.2.Verify input signal.3. Inspect connector connections. | Restore normal power/signal and re-seat connectors. |
| Insufficient output power | 1.Confirm band matching.2.Check load VSWR.3.Assess module temperature. | Match the correct band,optimize load matching,and improve heat dissipation. |
| Severe signal interference | 1.Check surrounding electromagnetic environment.2. Verify MIMO channel isolation. | Move away from interference sources and optimize channel configuration. |
| Overheating protection triggered | 1.Check installation environment.2. Assess thermal design. | Improve ventilation and optimize heat dissipation solutions. |
