K-IZV MAYRadioFans.CN 收音机爱 好者资料库2CDJ-3501234ABCDEF1234SAFETY INFORMATION Additional Laser Caution1. Laser Interlock Mechanism The position of the switch (S752) for detecting loading completion 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 terminal 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 cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam.IMPORTANTTHIS PIONEER APPARATUS CONTAINSLASER OF CLASS 1.SERVICING OPERATION OF THE APPARATUSSHOULD BE DONE BY A SPECIALLYINSTRUCTED PERSON.For CD Wave length (typ) : 790 nm Operation output : 4 mW CW, Class 1 Maximum output : Class 1 (Under fault condition)Laser Pickup specifications and Laser characteristicsWARNINGThis product may contain a chemical known to the State of California to cause cancer, or birth defects or other reproductive harm.Health & Safety Code Section 25249.6 - Proposition 65This service manual is intended for qualified service technicians ; it is not meant for the casual do-it-yourselfer.

SERVICE PRECAUTIONS1.1 NOTES ON SOLDERING1.2 ABOUT VOLTAGE MONITORING1.3 NOTE ON REPLACEMENT OF THE FL DISPLAY IN THE PNLB ASSY 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 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 reworking 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).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.This unit always monitors for power failure and will shut itself off immediately after an error is detected. If an error is generated, the STANDBY LED will flash after the unit shuts itself off. After the unit shuts itself off because of an error, unplug the AC power cord and wait 1 minute before turning the unit ON by pressing the STANDBY/ON key.Repair the unit, according to “5.5 ABOUT VOLTAGE MONITORING.”The fluorescent (FL) display on the control panel is attached to the board, using double-back tape. When replacing the FL display, new double-back tape is required. This part is not supplied as a service part, but we recommend using double-back tape (part No. GYH1033) as a general-purpose part for service. You can also use the double-back tape specified below, if available: Manufacturer: 3M, Tape width: 5 mm, Model No.: Y-4300K-08 and Y-4609 Or, tape that uses acrylic foam as a base material, with tape thickness of 0.8 mm, and with the peel force in 90 orientation (glass) of 20 N/cm or greaterThree pieces of double-back tape with the size of 5 mm 30 mm are required. First attach the pieces of tape to the places on the back of the FL display, as shown in the figure below, then attach it to the board. Be careful when working with double-back tape, because its adhesion strength is very high.PNLB Assy30 mm5 mmFL (face side)FL (back side)Double-back tapeDouble-back tape7CDJ-35056785678ABCDEF2.
