Parts marked with * require longer delivery time. The parts with no reference number or no parts number in the exploded views are not supplied. As regards the resistors and capacitors, refer to the circuit diagrams contained in this manual. Parts marked with this sign are safety critical components. They must be replaced with identical components - refer to the appropriate parts list and ensure exact replacement. Parts of mark can be used only with the version designated. US:U.S.A.

SAFETY INFORMATION This product has been designed and manufactured according to FDA regulations title 21, CFR, chapter 1, subchapter J, based on the Radiation Control for Health and Safety Act of 1968, and is classified as a class 1 laser product. There is no hazardous invisible laser radiation during operation because invisible laser radiation emitted inside of this product is completely confined in the protective housings. The label required in this regulation is shown 1. OCAUTION USE OF CONTROLS OR ADJUSTMENT OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. Optical pickup: Type: KSS-151A Manufacturer: SONY Corporation Laser output: Less than 0.2 mW on the objective lens Wavelength: 760 - 800 nm 1For U.S.A. RadioFans.CN 收音机爱 好者资料库 2-1-2 Objective Never look directly into the LD or observe the laser beam through another lens or mirror. Dont touch the objective with fingers. If objective becomes dirty, playback will deteriorate. To clean the objective, moisten a good cleaning tissue, such as made by KODAK, in isopropyl alcohol and wipe the objective gently. Wipe off and excess fluid with a dry cleaning tissue. 2-2 Sled balance adjustment 1.Adjust V403 for 0V potential between P415 pin 1 (SO) and pin 2 (GND). 2-1 Replacement of the Pickup Assembly 2-1-1 Cautions in handling Before removing the pickup assembly be sure to solder-bridge where indicated in the inset to prevent the laser diode from being electrostatically damaged. After replacing the pickup assembly, be sure to unsolder the antistatic bridge. Or else the laser diode does not function. Before servicing the pickup assembly be sure to prevent electrostatic-inducer destruction by grounding not only test equipment in use but also yourself. In case of mounting and dismounting the assembly, do not touch the actuator, photosensor and LD plate. Dont touch the plated portion of the flat cable end directly with fingers. Use care not to break the flat cable. Soldering must be done quickly at less than 30W, 320. Dont disassemble the pickup assy. Dont apply shock to the pickup assy. Dont place the assembly in a place subject to excessive dust, heat or moisture. 2 ADJUSTMENTS AND CHECKS 3 The pickup is secured with an anti-vibration clamp in order to reduce vibration during transport. This must be released before use. Releasing the anti-vibration clamp 1.Place the unit on its side, left side down, as shown here. 2.Use the supplied tool and insert it into the hole on the bottom. 3.Turn the tool about 30 degrees counter-clockwise in the FREE direction. Securing the anti-vibration clamp 1.Remove any disc from the unit, disconnect the power, and place the unit on its side, left side down, as shown here. 2.Use the supplied tool and insert it into the hole on the bottom. 3.Turn the tool about 30 degrees clockwise in the LOCK direction. NOTE: You do not need to use force to clamp and unclamp the unit. This may damage the unit. Use only the supplied tool and turn gently.
