34、plant. Do not disassemble or attempt to readjust it. Please observe the following instructions carefully in handling the pick-up. 1. Handle with Care (1) Storage Do not store the pick-up in dusty, high-temperatured or high-humidity environments. (2) Please take care for preventing from shock by fall

35、ing down or careless handling. 2. Protection of the LD Short a part of the LD circuit by soldering. After connection to a circuit, remove the short solder. Shorting Land Seen from the pattern side Pick-up SF-P200R FPC 3. Precautions when handling the CD mechanism ? Handle the laser pick-up so that i

36、t is not exposed to dust. ? Do not leave the laser pick-up bare. Be sure to cover it. ? If dust 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

37、 the bench, jig, head of soldering (with ceramic) iron and measuring instruments are well grounded. ? 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

38、so that damaging outside forces are not received. ? When carrying the finished mechanism, hold it by the chassis body. ? For proper operation, storage and operating environment should not contain corrosive gases. For example H2S, SO2 NO2, CL2 etc. In addition storage environment should not have mate

39、rials that emit corrosive gases especially from silicic, cyanic, formailn and phenol group. In the mechanism or the set, existence of corrosive gases may cause no rotation in motor. 14 D-107 MECHANISM AND FUNCTION OF CD MECHA 1. Traverse Mecha : TR Mecha Sub Assy (GEN5327) 2.
