The CLASS 1 LASER PRODUCT label is located on the rear exterior. This set employs laser. Therefore, be sure to follow carefully the instructions below when servicing.

15、 WARNING! WHEN SERVICING, DO NOT APPROACH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION. BE SURE TO OBSERVE FROM A DISTANCE OF MORE THAN 30cm FROM THE SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK. CLASS 1 KLASSE 1 LUOKAN 1 KLASS 1 LASER

16、 PRODUCT LASER PRODUKT LASER LAITE LASER APPARAT Precaution to replace Optical block (LPC-512A) 1) After the connection, remove solder shown in the right figure. Body or clothes electrostatic potential could ruin laser diode in the optical block. Be sure ground body and workbench, and use care the c

17、lothes do not touch the diode. Solder 5 DISASSEMBLY INSTRUCTIONS CAUTION BEFORE STARTING SERVICING Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to take a proper grounding treatment as required. Many screws are used inside the unit. To prevent missin

18、g, dropping, etc. of the screws, always use a magnetized screw driver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care of the tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used improperly, t

19、he screw holes will be easily damaged and the parts can not be fixed. CABINET DISASSEMBLY 1. Top Case 1) Release 7 screws (A).
