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.

Precautions for Using Optical Pick-up (KMS-280A)

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.

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.

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.

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 OPEN1 switch (S801) with tape.

SELF-DIAGNOSTIC

2-1. GENERAL

This set uses the self-diagnostic system in which if an error occurs in playback/recording mode, the error is detected by the model control and power control blocks of the microprocessor and information on the cause is stored as history in EEPROM. By viewing this history in test mode, it helps you to analyze a fault and determine its location.

2-2. TEST MODE SETTING

There are two different methods to set the test mode: 1 Short BP801 (TEST) on the main board with a solder bridge

(connect pin @§ of IC801 to the ground). Then, turn on the power.

2-4. RELEASING THE TEST MODE

For test mode set with the method 1: Turn off the power and open the solder bridge on BP801 on the main board. For test mode set with the method 2: Turn off the power.

2-5. SELF-DIAGNOSTIC MODE

1. Go into the test mode.

2. With the unit LCD indicators all flashing, press DISPLA Y key

to go into the self-diagnostic mode.

2 In the normal mode, use the keys on the unit to perform the

following operations: Press and hold down ( and press the keys below in this turn:

AND TO TAL RECORDING TIME

After repair, reset the error indication code. Reset the total recording time when you have replaced the OP.

1. Go into the self-diagnostic mode. (See page 5.)

2. To reset the error indication code, slide REC c key when

the code is displayed. (All data including 1st, N , N-1 and N-2 are reset.)

TEST MODE

4-1. GENERAL

This set provides the Overall adjustment mode (Assy mode) that allows CD and MO disk to be automatically adjusted when in the test mode. In this Assy mode, the system discriminates between CD and MO disk and then automatically perform adjustments for them in sequence. If a fault is found, the system displays its location. Also, the Serv o mode allows each indi vidual adjustment to be automatically adjusted.
