This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your ey

18、es and skin from laser radiation, the following precautions 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 away from the laser pick-up unit at all times. Do not stare at the laser beam at any time.

19、 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 in hazardous radiation exposure. Laser Emitting conditions: 1. This devic

20、e is a Class IIIb laser device. Class IIIb means With the protective case removed, exposure to the light output from the laser, either directly or reflected by a mirror, can cause harm to the eyes, but there is no danger to the eyes from exposure to dispersed reflected laser light. (Generally 0.5 W

21、or less) 2. Always wear eyeglasses designed for protection against laser light. 3. Always wear gloves. 4. Have no reflective objects anywhere near this device. 5. Figure A shows from where in this device the laser is emitted. 6. When switching on the power to the device for the first time, always me

22、asure the laser power with a laser power meter and check that the power is no greater than the number of Watts in the specifications. 7. Never look directly at the laser light while the laser is emitting light. 8. Do not allow the laser light to shine directly on your skin while the laser is emittin

26、city. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage c

27、aused by electro static discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped 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 b

28、e removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly 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

29、a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate electrical charge sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These

30、 can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum

31、 foil or comparable conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, 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

32、 circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) suff

33、icient to damage an ES device). Grounding for electro static breakdown prevention 1. Human body grounding: Use an anti static wrist strap to discharge the static electricity from your body. 2. Work table grounding: Put a grounded conductive material (sheet) or iron sheet on the area where the optica

34、l pickup is placed. Caution: The static electricity of your clothes will not be grounded through the wrist strap. So take care not to let your clothes touch the optical pickup. 1M Conductive material (sheet) or iron sheet Anti-static wrist strap MCX-1000 6 MCX-1000 I FRONT PANEL I REAR PANELS MCX-10
