This MiniDisc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the bottom exterior. IN NO EVENT SHALL SELLER BE LIABLE FOR ANY DIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY NATURE, OR LOSSES OR EXPENSES RESULTING FROM ANY DEFECTIVE PRODUCT OR THE USE OF ANY PRODUCT. "MD WALKMAN" is a trademark of Sony Corporation. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Precautions for Laser Diode Emission Check
When checking the emission of the laser diode during adjustments, never view directly downwards as this may lead to blindness.

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. 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.

Precautions for Using Optical Pick-up (LCX-2E) As the laser diode inside the optical pick-up damages by static electricity easily, solder the laser tap of the Optical pick-up flexible board when handling. Also take the necessary measures to prevent damages by static electricity. Handle the Optical pickup flexible board with care as it breaks easily.

SECTION 1 SERVICING NOTE
1) When repairing this device with the power on, if you remove the main board or open the upper panel assy, this device stops working. In this case, you can work without the device stopping by fastening the hook of the OPEN/CLOSE switch (SW board S809) with tape.

SW board S809

2) This set is designed to perform automatic adjustment for each adjustment and write its value to EEPROM. Therefore, when EEPROM (SYSTEM board IC802) has been replaced in service, be sure to perform automatic adjustment and write resultant values to the new EEPROM. Refer to section 5 Test Mode (page 11) for details. 3) Replacement of CXD2661GA-2 (IC601) and CXR701080-006GA (IC801) used in this set requires a special tool. Therefore, they cannot be replaced.

4-6. SELF-DIAGNOSTIC DISPLAY MODE 4-6-1. Outline of the function
The Self-diagnostic system is used in this set. If an error occurs during playback, this system detects the fault through the microprocessor's mechanism and power control blocks and stores the cause in EEPROM in a history format. This history, which can be viewed in the TEST MODE, provides the means of locating the fault in troubleshooting.
