12、UTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed ci

13、rcuit boards may not come printed withthe lead free mark due to their particular size): LEAD FREE MARKUnleaded solder has the following characteristics.Unleaded solder melts at a temperature about 40 C higherthan ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied

14、to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 C.Caution: The printed pattern (copper foil) may peel away ifthe heated tip is applied for too long, so be careful!Strong viscosityUnleaded solder is more viscou-s (sticky, less pro

15、ne to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.This appliance is classified asa CLASS 1 LASER product.The CLASS 1 LASERPROD

16、UCT MARKING islocated on the rear exterior.Laser component in this product is capable of emitting radiationexceeding the limit for Class 1.NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNITThe laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential d

17、ifference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

18、NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.LASER DIOD
