The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. This caution label is located inside the unit. The laser component in this product is ca- pable of emitting radiation exceeding the limit for Class 1. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. 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 soldering iron around 270C 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. SAFETY-RELATED COMPONENT WARNING ! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK !

During repair, pay attention to electrostatic breakdown 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 waveform is output two times. HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF Insert a tapering driver into the aperture of the unit bottom, and turn in the direction of arrow. *To close the disc table, turn the driver in the reverse direction.

FRONT PANEL In order to remove the front panel block when the power supply does not turn on, rotate the cam with tapering driver as the figure shows, and the loading part will be moved. Then pull out the loading part by your hand to remove the load- ing panel as the figure shows. After that take out the front panel block.

AF MODE The following checks can be performed in the AF mode, which is set by connecting the TP2 (AFADJ) terminal on MAIN board to the Ground and turning on the power. FL tube check After all segments light up, when the button is pressed con- tinuously, the following will be displayed. (Partial lighting 1) When the p button is pressed continuously, the following will be displayed. (partial lighting 2) When the OPEN/CLOSE button is pressed continuously, all will light up again. Key check All buttons have corresponding button numbers. When a button is pressed, the counter will count up and display the buttons num- ber. However, the counter will only count to “12”. It will not count for buttons already pressed once, but will display the buttons number.

ADJ MODE The following operations are performed in the ADJ mode, which is set by connecting the TP1 (ADJ) terminal to the Ground and turning on the power. During playback, there is no problem even if the GFS is continu- ously LOW. High speed search is prohibited during access. During playback, the gain of focus servo and spindle servo does not decrease. Servo related manual operations and measurement can be performed. (For details of operations, refer to Table of Key Operrations in ADJ Mode.) 4-3. CLV-S MODE The spindle servo for playback sets into the CLV-S mode when the TP1 (ADJ) terminal is connected to Ground after turning on the power. TABLE OF BUTTON OPERATIONS IN ADJ MODE The jitter value display mode can be set after the all-music remaining number mode using the TIME button. The functions of the number buttons are shown in the following table.
