Note: If the unit does not function properly, follow these troubleshooting steps: 1. Open the disc cover and inspect the laser lens for dust or debris. Gently clean the lens with a cotton swab and mild soapy water, then rinse thoroughly with clean water. Avoid using alcohol, as it may damage the lens if not completely rinsed. 2. If cleaning does not resolve the issue and the lens appears aged (e.g., fails to read discs when expected), carefully open the console and locate the small adjustment screw beside the lens assembly. Make a slight clockwise adjustment to increase laser output power. 3. If the lens fails to extend, disassemble the unit and manually rotate the gear or rod to move the optical assembly outward. Place a disc, power on the console, and test functionality. Package Includes: 1 × KSM-440AEM Laser Lens
