13、ed using the lead free solder.Among some types of lead free solder currently available, it is recommended to use one of the following types for the repairwork. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth)Caution:As the melting point temperature of t

14、he lead free solder is about 30C to 40C (50F to 70F) higher than that of the leadsolder, be sure to use a soldering iron suitable to each solder.About lead free solderWARNING: Laser SafetyThis product contains a laser beam component. This component may emit invisible, as well as visible radiation,wh

15、ich may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must beused during servicing of the unit.1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away fromthe laser pick-up unit at all times. Do

16、 not stare at the laser beam at any time.2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result inhazardous radiation exposure.Ra

During this time (5-10 sec.) the laser may radiate through the

18、lens of the laser pick-up unit. Do not attempt any servicing during this period!If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laseremissions.2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this l

19、evel has been set by the factoryprior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.Laser Diode PropertiesType:Semiconductor laser GaAlAsWav

Use cautionto prevent electrostatic damage when servicing or handling the DVD-mechanism.1. Grounding for electrostatic damage preventionSome devices, such as the DVD player,

25、 use an optical pickup (laser diode) that will be damaged by static electricity in theworking environment. Only attempt service after ensuring that all grounding procedures have been completed.1. Worktable groundingPut a grounded conductive material (sheet) or iron sheet on the area where the optica

Handle the DVD mechanism gently, as it is an extremely high-precision assembly.2. The flexible cable lines may break if an excessive

27、 force is applied to it. Use caution when handling the cable.3. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor.I LOCALE MANAGEMENT INFORMATIONLocale Management Information : This DVD player is designed and manufactured to respond to the LocaleMana
