Laser Interlock Mechanism The position of the switch (S9002) for detecting loading completion is detected by the system microprocessor, and the

9、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 terminal side. ( if LPS1 signal is low level ). In the test mo

10、de the interlock mechanism will not function. Laser diode oscillation will continue, if pin 5 (pin 3) of AN22022A (IC7002) on the SRVA Assy is connected to GND, or else the terminals of Q7002 (Q7001) are shorted to each other (fault condition).2.

21、formance 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. CleaningFor parts that require cleaning, such as optical pickups, tape deck heads, lenses

22、and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.3. Lubricants, Glues, and Replacement partsUse grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied.5. Shipping mode and Shipping screwsTo prot

23、ect 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-200056785678ABCDEFCONTENTS SAFETY INFORMATION.21. SERVICE PRECAUTIO

31、ES ON PANEL CPU For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. Compared with

32、 conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which rewo

33、rking is required and the weight of the tip of the soldering iron.Do NOT use a soldering iron whose tip temperature cannot be controlled.Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden)

34、.The following lead-free solders are available as service parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.NEVER replace the FLASH ROM (IC114) on the MAIN Assy during servicing.If the FLASH ROM is assumed to be defective, replace the whole MAIN Ass

35、y.This FLASH ROM contains data that can only be written in at the factory.An IEEE 802.3-based MAC address specific to this unit has been written.After the PANEL CPU (IC8003) is replaced, update its program.The built-in PANEL CPU contains a FLASH ROM and will not operate without a program.For updatin

36、g, proceed as follows: 1. Insert the USB flash memory device that contains the program. 2. While holding the USB STOP key pressed, turn on the unit. Hold the USB STOP key pressed until the “Pioneer” logo disappears. 3. Updating starts.8CDJ-20001234ABCDEF12341.4 NOTES ON LINK CONNECTOR1.5 NOTES ON LC
