5.3 DMX Connection (Optional)
For DMX control, connect a DMX controller to the DMX IN port of the first fixture in your chain using a 3-pin XLR DMX cable. Connect the DMX OUT of the first fixture to the DMX IN of the next, and so on. Terminate the last fixture in the chain with a DMX terminator (not included) to prevent signal reflection issues.
6. Operating Instructions

9. Troubleshooting
If you encounter issues with your LM0740, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fixture does not power on. | No power, faulty cable, blown fuse. | Check power connection, test power cable, replace fuse if necessary. |
| No DMX control. | Incorrect DMX address, faulty DMX cable, no DMX signal, missing terminator. | Verify DMX address, check DMX cable connections, ensure DMX controller is active, add DMX terminator to the last fixture. |
| Fixture not responding in Sound-activated mode. | Low sound sensitivity, no sound input. | Increase sound sensitivity in the menu, ensure sufficient sound is present. |
| Movement or light output is erratic. | Interference, internal fault. | Check for strong electromagnetic interference. If problem persists, contact support. |
