SECTION 1 SERVICING NOTES
CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the "S curve check" in "CD section adjustment" and check that the S curve waveforms is output three times. Notes on chip component replacement · Never reuse a disconnected chip component. · Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing · Keep the temperature of the soldering iron around 270 °C during repairing. · Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). · Be careful not to apply force on the conductor when soldering or unsoldering.
Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. The following caution label is located inside the unit.
CAUTION
INVISIBLE LASER RADIATION WHEN INTERLOCKS DEFEATED. AVOID EXPOSURE TO BEAM.

Load a commercially available 10-minute tape into the decks A and B respectively. (If a 10-minute tape is not available, another tape may be used but a cycle time will be longer.) 2. Select the function "TAPE". 3. Rewind tapes in advance by pressing 0 button respectively on decks A and B. 4. Press three buttons [SPECTRUM ANALYZER] , [ENTER], and [KARAOKE PON/MPX] simultaneously. 5. Press · button on deck A. (This button triggers the aging mode.) 6. The aging mode is activated if "AGING A" is displayed on the fluorescent indicator tube. 7. In the aging mode, the aging is executed in a sequence given in "2-2. Operation during Aging Mode". The aging continues unless an alarm occurred. 8. To exit from the aging mode, press I /u button to turn the set OFF.
2-2. Operation during Aging Mode In the aging mode, the program is executed in the following sequence. 1. A tape on FWD side is played for one minute. 2. PAUSE STOP is made. 3. Recording is made for 3 minutes. (For the deck not having the record function, the play is executed.) 4. FF is executed up to the end of tape. 5. A tape is reversed, and the tape on REV side is played for one minute. 6. PAUSE STOP is made. 7. Recording is made for 3 minutes. (For the deck not having the record function, the play is executed.) 8. FF is executed up to the end of tape. 9. Steps 1 through 8 are executed for the other deck. 10.

CD SECTION
Note: 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks.

Procedure: 1. Connect oscilloscope to test point TP (FEO). 2. Connect between test point TP (FOK) and GND by lead wire. 3. Turn Power switch on. 4. Put disc (YEDS-18) in and turned Power switch on again and actuate the focus search. (actuate the focus search when disc table is moving in and out.) 5. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 3 ± 1 Vp-p.

Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. · · · · U : B+ Line. V : B Line. H : adjustment for repair. Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. Circled numbers refer to waveforms. Signal path. F : TUNER (FM/AM) E : PB (DECK A) d : PB (DECK B) G : REC (DECK B) J : CD c : digital out N : MIC INPUT Abbreviation AR : Argentine model. AUS : Australian model. MX : Mexican model. SAF : South African model. Note on Printed Wiring Boards: · X : parts extracted from the component side. ¢ : internal component. · · b : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A)
