Features

Small body almost the size of a MiniDisc jacket Ideal weight and size; fits in your shirt pocket. Personalized sound through Digital Sound Preset functions You can store two sets of sound quality adjustments (made during playback) to two switches. Low power-consumption design enables extended battery life. Simple One-Touch Eject function for easy MiniDisc handling A single press of the OPEN button causes the player lid to open and the MiniDisc to eject. Easy-to-operate headphones remote control with backlit LCD The LCD displays disc and track information, playback mode as well as battery condition. Keep the main unit in your pocket and operate the MiniDisc player through the slim stick remote control. Shock-resistant memory offsets up to 40 seconds of optical read errors.

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 above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-2E) 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 measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care. When repairing this set with the power on, if you remove the upper panel assy, this set stops working. In this case, you can work without the set stopping by fastening the hook of the open/close detect switch (SW board (S809)) with tape.

Mode to adjust or check the operation of the set by function. Normally, the adjustment in this mode is not executed. However, the Manual mode is used to clear the memory before performing automatic adjustments in the Overall Adjustment mode. Transition method in Manual Mode 1. Setting the test mode. (See page 9) 2. Press the [VOL +] key activates the manual mode where the LCD display as shown below.

3. During each test, the optical pick-up moves outward or inward while the N > or. key is pressed for several seconds respectively. 4. Each test item is assigned with a 3-digit mode number; 100th place is a major item, 10th place is a medium item, and unit place is a minor item.
5. The display changes a shown below each time the [DISPLAY] key is pressed.
Self-Diagnosis Display Mode
This set uses the self-diagnosis system in which if an error occurs in playback 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. 1. Setting the test mode. (See page 9) 2. In the display check mode, press the [DISPLAY] key activates the self-diagnosis display mode where the LCD display as shown below.

SECTION 5 ELECTRICAL ADJUSTMENTS
In this set, automatic adjustment of CD and MO can be performed by entering the test mode. (See page 9) However, before starting automatic adjustment, the memory clear and power adjustment must be performed in the manual mode. A key having no particular description in the text, indicates a remote commander key.

2. Press the X key.
Precautions for Adjustment
1. Adjustment must be done in the test mode only. After adjusting, release the test mode. 2. Use the following tools and measuring instruments.

SECTION 7 EXPLODED VIEWS

NOTE: -XX and -X mean standardized parts, so they may have some difference from the original one. Color Indication of Appearance Parts Example: KNOB, BALANCE (WHITE). (RED) Parts Color Cabinet's Color Items marked * are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. The mechanical parts with no reference number in the exploded views are not supplied. Accessories and packing materials are given in the last of the electrical parts list. The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified.
