MZ-NF810/NF810CK SECTION 1 SERVICING NOTES NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-5R) The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care. System requirements The following hardware and software are required in order to use the SonicStage software for the Net MD.
