Detailed Answer
Industrial remote LED indicator meanings (Leader LD series): green slow blink = normal standby; green fast blink = transmitting; red steady = low battery; red/green alternating = signal loss/emergency stop; yellow = pairing mode. Xingjia indicator logic is similar. Understanding the LEDs helps quickly judge faults: no light → check battery first, red → check power, abnormal flashing → check pairing.
| Green | Normal / transmitting |
| Red | Low battery |
| Alternating | Signal loss |
