    DISASSEMBLY INSTRUCTIONS -1/3 Disassembly Cautions before disassembly: When disassembling this unit and reassembling it after repair, be careful of the following to ensure safety and reliable performance: 1. Remove the mini-disc from this unit. 2. Take great care not to use screws of greater lengths when installing MD mechanism block (screws that secure components to be installed in MD block mechanism chassis): A longer screw will contact the optical pickup, which could result in no operation.
