Health & Safety Code Section 25249.6 - Proposition 65 ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURN- ING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and m

6、echanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special

7、 safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics

8、 as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service

9、 Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER. (FOR USA MODEL ONLY) 1. SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK

10、Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.)

11、. Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA. Device under test Leakage current tester Earth ground Reading should not be above 0.5 mA Also test with plug reversed (Using AC adapter plug as

12、required) Test all exposed metal surfaces AC Leakage Test RadioFans.CN 收音机爱 好者资料库 3TAD-D600 5678 5678 A B C D E F WARNING ! THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. A S

13、PECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS. LASER DIODE CHARACTERISTICS FOR CD : MAXIMUM OUTPUT POWER : 7 mW WAVELENGTH : 780 nm FOR SACD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nm) Additional Laser Caution 1. Laser Interlock Mechanism Loading switch (S101 on th

14、e LOAB Assy) is used for interlock mechanism of the laser. When this switch turned ON in SW2 (CLOSE) side (OPEN signal is 0V and CLOSE signal is 3.5V), a laser becomes the status which can completely oscillation. Furthermore, the laser completely oscillates in the disc judgment and disc playback. Wh

15、en player is power ON state and laser diode is not completely oscillating, 780nm laser diode is always oscillating by half power. Laser diode is driving with Q307 (650nm LD) and Q308 (780nm LD) on the DVDM Assy. Therefore, when short-circuit between the emitter and collector of these transistors or

16、the base voltage is supplied for transistors turn on, the laser oscillates. (failure mode) In the test mode , there is the mode that the laser oscillates except for the disc judgment and playback. LD ON mode in the test mode oscillates with the laser forcibly. The interlock mechanism mentioned above

17、 becomes invalid in this mode. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam.

18、rocedures that must be performed during repairs are marked with the below symbol. Please be sure to confirm and follow these procedures. 1. Product safety Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by following the safe

19、ty instructions described in this manual. 1 Use specified parts for repair. Use genuine parts. Be sure to use important parts for safety. 2 Do not perform modifications without proper instructions. Please follow the specified safety methods when modification(addition/change of parts) is required due

20、 to interferences such as radio/TV interference and foreign noise. 3 Make sure the soldering of repaired locations is properly performed. When you solder while repairing, please be sure that there are no cold solder and other debris. Soldering should be finished with the proper quantity. (Refer to t

21、he example) 4 Make sure the screws are tightly fastened. Please be sure that all screws are fastened, and that there are no loose screws. 5 Make sure each connectors are correctly inserted. Please be sure that all connectors are inserted, and that there are no imperfect insertion. 6 Make sure the wi

22、ring cables are set to their original state. Please replace the wiring and cables to the original state after repairs. In addition, be sure that there are no pinched wires, etc. 7 Make sure screws and soldering scraps do not remain inside the product. Please check that neither solder debris nor scre

23、ws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one. 9 Th

24、ere should be no spark traces or similar marks on the power plug. When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary. a Safe environment should be secured

25、during servicing. When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2. Adjustments To keep the original performance of the products, optimum adjustments

26、and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual. 4. Cleaning For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, pr

27、oper cleaning should be performed to restore their performances. 3. Lubricants, Glues, and Replacement parts Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied. 5. Shipping mode and Shipping screws To protect products from damages or failures d

28、uring transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual. 5TAD-D600 5678 5678 A B C D E F CONTENTS SAFETY INFORMATION .2 1. SERVICE PRECAUTIONS.6 1.1 NOTES ON SOLDERING
