- Connect Power: Plug the power cable into the machine and then into a standard electrical outlet (AC 110-130V, 50/60Hz).
- Power On and Warm-up: Flip the 'POWER' switch to the 'ON' position. The prompt lamp on the machine's control panel will illuminate (typically green) and then turn off, indicating the machine is warming up. The rapid warm-up system typically takes 2-3 minutes. Once the prompt lamp turns red, the machine is ready for use.
6. Operating Instructions
The Donner DFM-500 offers flexible control over fog output and LED lighting.

6.1 Fog Output Control
- Wired Remote Control: Once the machine is warmed up (prompt lamp is red), press and hold the button on the wired remote to emit fog. Release the button to stop.
- Wireless Remote Control: Ensure the wired remote is connected to the machine. Press the button on the wireless fog remote to emit fog. Release to stop. The wireless remote has an operating range of up to 50 meters without obstacles.


6.2 RGB LED Light Control
- Activate Lights: Flip the 'LED LIGHT' switch on the machine to the 'ON' position.
- Change Colors/Modes: Use the dedicated RGB LED wireless remote control to select from 13 different colors and various lighting-change modes (e.g., flash, fade, strobe, smooth).
- Independent Operation: The LED lights can be turned on or off independently of the fog output.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your fog machine.
- Cleaning: After each use, especially if storing for an extended period, run a small amount of distilled water through the machine to help prevent clogs.
- Exterior Cleaning: Wipe the exterior of the machine with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the fog machine in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the reservoir is empty or contains fresh fog liquid before storage.
8. Troubleshooting
If you encounter issues with your Donner DFM-500, refer to the following common problems and solutions:

- No Fog Output / Machine Not Working:
- Warm-up Status: Ensure the machine has completed its warm-up cycle. The prompt lamp should be red, indicating it is ready. If the lamp is off, it is still warming up.
- Remote Button: The machine does not automatically spray fog. You must press and hold the button on either the wired or wireless remote to initiate fog output. Release to stop.
- Liquid Level: Check that the fog liquid reservoir is sufficiently filled and the metal liquid nozzle is fully immersed in the atomizing liquid. Insufficient liquid will prevent proper operation.
- Self-Protection Mode: The machine may automatically stop for approximately five minutes due to a self-protection mechanism (e.g., overheating). It will restart after cooling down.
- Wireless Remote Not Responding:
- Wired Remote Connection: For the wireless fog remote to function, the wired remote control must be plugged into the machine's 'CONTROLLER' port.
- Battery Check: Ensure the battery in the wireless remote is functional.
- LED Lights Not Working:
- LED Switch: Verify that the 'LED LIGHT' switch on the machine is in the 'ON' position.
- Remote Battery: Check the battery in the RGB LED wireless remote control.
