Detailed Answer
Receiver indicator troubleshooting: 1. Power light off: supply problem (fuse/wiring/voltage); 2. Signal light blinking constantly: not paired/weak signal (re-pair/check antenna); 3. Output light abnormal: relay fault; 4. All lights flashing randomly: interference (find the interference source). Lider LD series receiver indicators have clear status definitions (see the manual). If uncertain, return to the factory.
| Power light | Check supply |
| Signal light | Pairing/antenna |
| Random flashing | Interference source |
Note:Check the manual first for abnormal indicators — don't disassemble blindly.
