SAFETY INFORMATIONThis service manual is intended for qualified service technicians; it is not meant for the casualdo-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have beentrained to properly and safely repair complex products such as those covered by this manual.Improperly performed repairs can adversely affect the safety and reliability of the product and mayvoid the warranty. If you are not qualified to perform the repair of this product properly and safely, youshould not risk trying to do so and refer the repair to a qualified service technician. LABEL CHECK1. Laser Interlock MechanismON/OFF switching of the switch for detecting loading state,ON/OFF switching of the clamp completion, close comple-tionand shutter switches are detected by the system micropro-cessor. The design of this interlook mechanism preventslaser diode oscillation when even one of the clamp completion,close completion and shutter switches is OFF (High level). Accordingly, the interlock will no longer function and thelaserdiode will oscillater if all three of these switcher are setdeliber-ately to ON(Low level).The interlock also does not function in the test mode.Laser diode oscillation will continue, if pin 1 of M51593FP(IC101) on the PRE AMP BOARD ASSY mounted on thepickupassembly is connected to GND, or pin 19 is connected tolow level (ON), or else the terminals of Q101 are shorted toeach other (fault condition).2. When the cover is opened, close viewing of the objective lenswith the naked eye will cause exposure to a Class 1 laserbeam.

The mark found on some component parts indicates the importance of the safety factor of the part.Therefore, when replacing, be sure to use parts of identical designation. Reference Nos. indicate the pages and Nos. in the service manual for the base model. When ordering resistors, first convert resistance values into code form as shown in the following examples.Ex. 1When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown byJ = 5%, and K = 10%).560 = 56 10 1 = 561.
