Do notdisassemble or attempt to readjust it. Please observe the following

33、 instructions carefully in handling the pick-up.1. Handle with Care(1) StorageDo not store the pick-up in dusty, high-temperatured or high-humidity environments.(2) Please take care for preventing from shock by falling down or careless handling.2. Protection of the LDShort a part of the LD circuit b

34、y soldering. After connection to a circuit, remove the short solder.Shorting LandSeen from thepattern sidePick-upSF-P200R FPC3. Precautions when handling the CD mechanism? Handle the laser pick-up so that it is not exposed to dust.? Do not leave the laser pick-up bare. Be sure to cover it.? If dust

35、adheres on lens of the pick-up, blow it off with a blower brush.? Do not shock the laser pick-up.? Do not watch the light of the laser pick-up.4. Cautions on assembling and adjustment? Be sure that to the bench, jig, head of soldering (with ceramic) iron and measuring instruments are well grounded.?

36、 Workers who handle the laser pick-up must be grounded.? The finished mechanism (prior to anchoring in the set) should be protected against static electricity and dust.The mechanism must be stored so that damaging outside forces are not received.? When carrying the finished mechanism, hold it by the

37、 chassis body.? For proper operation, storage and operating environment should not contain corrosive gases. For example H2S, SO2NO2, CL2 etc. In addition storage environment should not have materials that emit corrosive gases especially fromsilicic, cyanic, formailn and phenol group. In the mechanis

38、m or the set, existence of corrosive gases may cause norotation in motor.14D-107MECHANISM AND FUNCTION OF CD MECHA1. Traverse Mecha :TR Mecha Sub Assy (GEN5327)2.
