                        Note(Please pay attention):
                        1. Please wear laser goggles during usage and avoid touching the laser directly with your eyes and skin!
                        2. Do not engrave mirror objects, pay attention to fire, pay attention to pets when working!
                        3. Smoke will be generated when burned, please pay attention to smoke exhaust indoors.
                        4. This laser module is compatible with our NEJE machine. 

                        Note: For the New NEJE 20W laser module, the working status of the fan is determined by the temperature of the module, and the fan speed is dynamically adjusted according to temperature changes. When the machine stops working, the fan will stop working when the laser temperature drops.
