There is no hazardous invisible laser radiation duringoperation because invisible laser radiation emitted inside of this productis completely confined in the protective housings.The label required in this regulation is shown 1.OCAUTIONUSE OF CONTROLS OR ADJUSTMENT OR PERFORMANCE OFPROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT INHAZARDOUS RADIATION EXPOSURE.Optical pickup:Type: KSS-151AManufacturer: SONY CorporationLaser output: Less than 0.2 mW on the objective lensWavelength: 760 - 800 nm1For U.S.A.RadioFans.CN 收音机爱 好者资料库2-1-2 ObjectiveNever look directly into the LD or observe the laser beamthrough 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 asmade by KODAK, in isopropyl alcohol and wipe the objectivegently. Wipe off and excess fluid with a dry cleaning tissue.2-2 Sled balance adjustment1.Adjust V403 for 0V potential between P415 pin 1 (SO) and pin2 (GND).2-1 Replacement of the Pickup Assembly2-1-1 Cautions in handlingBefore removing the pickup assembly be sure to solder-bridgewhere indicated in the inset to prevent the laser diode frombeing electrostatically damaged. After replacing the pickupassembly, be sure to unsolder the antistatic bridge. Or else thelaser diode does not function.Before servicing the pickup assembly be sure to preventelectrostatic-inducer destruction by grounding not only testequipment in use but also yourself.In case of mounting and dismounting the assembly, do nottouch the actuator, photosensor and LD plate.Dont touch the plated portion of the flat cable end directly withfingers.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 CHECKS3The pickup is secured with an anti-vibration clamp in order toreduce vibration during transport. This must be releasedbefore use.Releasing the anti-vibration clamp1.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 theFREE direction.Securing the anti-vibration clamp1.Remove any disc from the unit, disconnect the power, andplace 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 LOCKdirection.NOTE: You do not need to use forceto clamp and unclamp theunit. This may damage theunit. Use only the suppliedtool and turn gently.SERVO PCBV403P415183 EXPLODED VIEWS AND PARTS LISTEXPLODED VIEW-141223345667889900qweertyuiopasdfghjkl;zxcvn!#$# #&%*m(b)5EXPLODED VIEW-1REF.NO.PARTS
