This component may emit invisible, as well as visible radi-ation, which may cause eye damage. To protect your eyes

16、and skin from laser radiation, the following pre-cautions must be used 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/1 feet away from the laser pick-up unit at all times. Do not stare at the laser beam at any t

During this time

19、 (5-10 sec.) the laser may radiate through the 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 ex-posed to any laser emissions.2) The laser power level can be adjuste

24、echanism is very sensitive for dropping or giving shocks.Warning for power supply5CD-S700CD-S700Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integ

25、rated circuits and some field-effect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge (ESD).1. Immediately before handling any semiconductor component or semiconductor-equipped

26、 assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test.2. After removing an electrical assembly

27、 equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.4. Use only an anti-static solder removal device. Some solder re

28、moval devices not classified as “anti-static (ESD protect-ed)” can generate electrical charge sufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective pa

29、ckage until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material).7. Immediately before removing the protective material from the leads of a replacement E

30、S divice, touch the protective material to the chassis or circuit assembly into which the device will be installed.CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackaged replacement ES devices. (Oth

31、erwise harmless motion such as brushing together of your fabric clothes or lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device).Grounding for electrostatic breakdown prevention1. Human body grounding.Use the antistatic wrist strap to dis

32、charge the static electricity from your body.2. Work table grounding.Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet.Caution:The static electricity of your clothes will not be grounded through the wrist strap. So take care not to l
