Welcome to the Nd:YAG laser installation tutorial, we will then guide you step by step through the installation of your equipment. First, unpack and remove the main unit, control system, treatment handle and other components. Check whether the equipment is complete, including the emergency stop button, key switch, display screen and other key components. Before installation, please make sure the working environment meets the requirements. Remove the handle from the box, align it with the plug box on the main frame, make sure the contact pins are aligned, gently turn the knob and tighten the connection. Finally, the handle mounts the treatment head and the unit is turned on to check for proper operation. At this point, your Nd:YAG laser installation is complete.
