Handling the Laser PickupIn case of repair or replacement of the Laser Pickup, payattention to the following handling instructions since the la-ser diode in the Laser Pickup is not resistant to static elec-tricity.(1)GroundingWhen you rep

14、air a Laser Pickup, first ground the hu-man body, as well as the measuring instruments andother tools (with particular caution to soldering iron).Whats more, your workbench and floor should desir-ably be grounded using conductive sheet or copperplate. See Fig. 1.2.NOTE: Be careful so as not to let y

15、our clothes touchthe Laser Pickup, as static electricity on theclothes will not be released even if your bodyis grounded.THIS COMPACT DISC PLAYER IS CLASSIFIEDAS A CLASS 1 LASER PRODUCT.THE CLASS 1 LASER PRODUCT LABEL ISLOCATED ON THE REAR EXTERIOR.CLASS 1LASER PRODUCT(2)Discharge of ElectricityBe s

16、ure to discharge electricity from objects brought intocontact with the Laser Pickup (i.e., soldering iron, tweezers,probes, volt-ohm-meter probes, etc.) before starting workby contacting them with the body chassis. Besides, nevertouch the Laser Pickup while power is applied.(3)Soldering Iron to be U

17、sedThe soldering iron for use in repair work should be: (1) aceramic soldering iron, (2) a soldering iron with its metalpart grounded, or (3) a soldering iron whose insulation re-sistance after five minutes of power application is 10 M-ohmor more at 500 VDC. Soldering should be completedpromptly, at

18、 a soldering iron temperature of 320 max (39W). A soldering iron heated above this temperature canbreak down the laser diode.Fig. 1.2 Handling the Laser Pickup(NO GOOD)(GOOD)1MConductive Sheet orCopper PlateWrist-strapfor GroundingLaser Pickup1MSS-9 GeneralivSchematicRef.
