1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it­yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained
to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.

THE AEL(ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1
BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR
CLASS1.
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.

LASER DIODE CHARACTERISTICS

MAXIMUM OUTPUT POWER: 5 mW
WAVELENGTH: 708- 785 nm

WARNING

LABEL CHECK

Additional Laser Caution

1. Laser Interlock Mechanism
The loading position detect switch (in CD mechanism
assembly) is set to "CLMP ON(CD CLOSE)" (ON:low
level,OFF:high level) position, the system control
IC(IC5501) get the "CLMP" signal, and hand the laser
"LDON" signal to IC1101.
Then a laser diode can be lighted except when the level of
signal CLMP is low.
The interlock also does not function in the test mode∗.
Laser diode oscillation will continue, if pin 9 of TA2150FN
(IC1101) on the SELF-CHUCK VCD ASSY is connected to
GND, or pin 10 is connected to low level (ON), or else the
terminals of Q1101 are shorted to each other (fault
condition).

2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 1
laser beam.

∗ : Refer to page 32.

5. PCB PARTS LIST

NOTES:•The mark found on some component parts indicates the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.

•

Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).

560 Ω→56 × 10
47k Ω→47 × 10

0.5 Ω→R50 ..................................................................................... RN2H

1

→ 561 ........................................................ RD1/4PU 5 6 1 J

3

→ 473 ........................................................ RD1/4PU 4 7 3 J

R 5 0

K

1 Ω→1R0 ..................................................................................... RS1P 1 R 0 K

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

5.62k Ω→ 562 × 10

1

→ 5621 ......................................................RN1/4PC 5 6 2 1 F

6. ADJUSTMENT

6.1 TEST MODE

Kind of test mode

The following four modes exist.
The door opening function with the infrared rays sensor becomes off in the test mode (Infrared rays is not irradiated).

1-1. TEST mode. (TEST) : For adjustment in main body distance of production line
1-2. Unit TEST mode. (UTEST) : For inspection by the function checker of production line

1-3. Service TEST mode. (STEST) : For inspection by service

It is not possible to operate at all by recognition because of there is no AC pulse if it is CD tuner alone and there is no part AMP as the power

failure.

Then, to be able to move the CD tuner, mode yet in the inconvenience without the part AMP.
It is possible to operate only in the CD tuner even if the part AMP is not connected.
An initial function becomes CD if the product starts in this mode, and CD becomes CD TEST mode different from a usual operation.
Even if the function is returned to the CD function again, the product does not become CD TEST mode when the function is made functions

other than CD once. The product becomes a usual CD operation.

To put the product from the state in the CD TEST mode, the remote control code of A25F is received.

1-4. CD TEST mode. (STEST) : For inspection by service
When the remote control code of A25F is received at the CD function when it is on, power becomes CDTEST mode.
The CD tuner is effective to this even the ordinary mode.
However, the product becomes off this mode when the function is changed besides CD.
The step in the part CD can operate. From LD ON to SPDL LOCK , TRKG ON/OFF and etc.

6.1.1 How to Start/Cancel Service Test Mode

It returns for the key input or the trigger input for the buzzer as SLEEP mode at time usually.

For "L" buzzer ON/OFF input.

Terminal CARR : The remote control code which corresponds to the pushed key is transmitted.

Carrier 40KHz, 1/3 Duty, Frame cycle 26ms.

Terminal E1 : If "H" pulse of 50-200ms is input two times between 0.5-1.5S in the terminal E2, the buzzer is output.

The buzzer is output if "H" pulse of 50-200ms is input two times between 0.5-1.5S in the terminal E2.

· Frequency of buzzer : 3KHz.

· How to sound the buzzer is as follows.
100ms sounding 100ms rest 100ms is sounded.
500ms rest, and 100ms repeated sounding, 100ms rest, and 100ms is sounded and it ends (Enter SLEEP).

*The buzzer is not output for 50ms or less and 200ms or more.
*The buzzer output is not done, except when the interval of the pulse of two times is 0.5-1.5S.

(Enter SLEEP when 1.5S is passed from the pulse of the first time.)

*This terminal is checked if there is no key input when returning from SLEEP.

(This terminal is not checked, except when returning for the key input.)

*When there is a key input when the width of the pulse and the interval are measured, the mode is made a key input
and the measurement of the pulse is discontinued.

Terminal D6 : "H" Fix.
Terminal D7 : "L" Fix.

For "H" buzzer ON/OFF input.

Terminal CARR : "L" Fix.
Terminal E1 : "L" Fix.

Terminal D6 : The remote control code which corresponds to the pushed key is transmitted.

There is no carrier.

Terminal D7 : Only when the remote control code is transmitted, "H" is output.

*It is made "H" before the remote control code is transmitted. After 10ms, it is made "L" after the key is turned off,
and the last remote control code is transmitted.
