Note: If the device does not function properly, please follow these steps: 1. Open the disc cover and check for dirt on the laser head. Clean the laser head using a cotton swab and soapy water, then rinse with clean water. Avoid using alcohol, as it may damage the laser head if not completely removed. 2. If cleaning does not resolve the issue and the laser head shows signs of aging (e.g., failure to read discs when it should), carefully disassemble the unit and locate the small adjustment knob on the side of the laser head. Gently adjust it slightly to increase laser output power. 3. In cases where the laser head is stuck and fails to extend, disassemble the unit, manually rotate the gear (or rod), shift the optical head outward, place the disc, restart the console, and test functionality. This method is recommended for users experiencing laser head blockage. Package Includes: 1 Piece KSM440AEM Laser Lens
