4、pletion is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch is not in LPS1 terminal side (when the mechanism is not clamped and LPS1 signal is high level.) Thus, the interlock will no longer function if the switch is deliberately set to LPS1 term

5、inal side. ( if LPS1 signal is low level ). In the test mode the interlock mechanism will not function. Laser diode oscillation will continue, if pin 41 of TC94A15FG (IC201) on the MAIN Assy is connected to GND, or else the terminals of Q201 are shorted to each other (fault condition). 2. When the c

6、over is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam. IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1.

11、 1234 A B C D E F 1234 Important Check Points for Good Servicing In this manual, procedures 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 radia

12、tion regulations), and maintain a safe servicing environment by following the safety 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 sp

13、ecified safety methods when modification(addition/change of parts) is required due 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 an

14、d other debris. Soldering should be finished with the proper quantity. (Refer to the 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 conn

15、ectors are inserted, and that there are no imperfect insertion. 6 Make sure the wiring 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

16、do not remain inside the product. Please check that neither solder debris nor screws 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 damag

17、es. If you find a damaged power cord, please exchange it with a suitable one. 9 There 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.

18、Please exchange the power cord if necessary. a Safe environment should be secured 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.

19、Adjustments To keep the original performance of the products, optimum adjustments 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 op

20、tical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper 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

21、. Shipping mode and Shipping screws To protect products from damages or failures during 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. 5CDJ-350 5678 5678 A B C D E
