SECTION 1 SERVICING NOTES
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 Never look into the laser diode emission from right avove when checking it for adustment. It is feared that you will lose your sight.

· Model Identification There are three types of main board in according of destination for MDX-C8500R. MAIN BOARD (Component Side)
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (KMS-241C/J1NP) The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform m easures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care.

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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. TYPE C
SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

Setting the clock
The clock uses a 12-hour digital indication. Example: To set the clock to 10:08
1
Press (MENU), then press either side of (DISC/PRST) repeatedly until "Clock" appears.
1 Press (ENTER).
The hour indication flashes.
2 Press either side of (DISC/PRST) to set the hour.
3 Press (+) side of (SEEK/AMS).
The minute indication flashes.
4 Press either side of (DISC/PRST) to set the minute.
2
Press (ENTER).
The clock starts.
After the clock setting is completed, the display returns to normal playback mode.
Tip You can set the clock automatically with the RDS feature (see page 24). (MDX-C8500R) Note In the initial setting, the clock indication appears while the unit is turned off. When you select the "on" setting of the "D.Info" item (page 29), you can see the clock indication in the upper part of the display while you are enjoying any source.

NOTES FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Schematic Diagram: · All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. · All resistors are in and 1/4 W or less unless otherwise specified. f · : internal component. · C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. · U : B+ Line. · Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords. · 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.
