To protect your eyes and skin from laser radiation, the following precautions must be used duringservicing 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 thelaser pick-up unit at all time

15、s. Do 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 exposur

16、e.Laser Emitting conditions:1. This device is a Class IIIb laser device when the protective case is removed.Class IIIb meansThe output is such that exposure to the light from the laser, either directly or reflected by a mirror, can cause harm to theeyes, but that there is no danger to the eyes from

17、exposure to dispersed reflected laser light. (Generally 0.5 W 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

18、 on the power to the device for the first time, always measure the laser power with a laser power meterand 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

19、shine directly on your skin while the laser is emitting light.RadioFans.CN 收音机爱 好者资料库CDR-HD1000CDR-HD1000ATTENTION - RADIATION VISIBLE ET / OU INVISIBLE LORSQUE LAPPAREILEST OUVERT.

BETRAKTA EJSTRLEN.I PREVENTION OF ELECTRO STATIC DISCHARGESome semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrosta

21、tically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors andsemiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused byelectro static discharge (ESD).1. Immediately

22、 before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body bytouching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should beremoved for potential shock reasons prior to applying p

23、ower 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, toprevent electrostatic charge buildup or exposure of the assembly.3. Use only a grounded-tip soldering iron to solder or unsolder ES devic

24、es.4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generateelectrical charge sufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES device

25、s.6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Mostreplacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparableconductive material).7. Immediately before rem

26、oving the protective material from the leads of a replacement ES divice, touch the protective material to thechassis 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

27、 motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushingtogether of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage anES device).Grounding for electrostatic breakdown pre
