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 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 is aging (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. 3. If the laser head is stuck and unable to extend, disassemble the unit, manually rotate the gear (or rod) to move the optical head outward, insert the disc, restart the console, and test functionality. This method is recommended if the laser head appears to be jammed. Package includes: 1 x KSM-440AEM Laser Lens
