Note: If the device is not functioning properly, please follow these steps: 1. Open the disc cover and check for dirt on the laser head. Clean the laser head gently with 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 appears weak (failing to read discs when it should), carefully disassemble the unit and locate the small adjustment knob on the side of the laser head. Slightly adjust the knob to increase laser output power. 3. In cases where the laser head is stuck and fails to extend, disassemble the console, manually rotate the gear (or rod), shift the optical head outward, insert the disc, restart the system, and test functionality. This method is recommended for users experiencing mechanical blockage. Package Includes: 1 Piece KSM440AEM Laser Lens
