SAFETY INFORMATION

CAUTION

Where in a manufacturer’s service documentation, for example in circuit diagrams or lists
of components, a symbol is used to indicate that a specific component shall be replaced only
by the component specified in that documentation for safety reasons, the following symbol shall
be used:

This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.
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.

CAUTION:

USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

- Safety Precautions for those who Service this Unit.
When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable
results.

Caution:

1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept.

2. During repair or tests, do not view laser beam for 10 seconds or longer.

WARNING

This product may contain a chemical known to the State of California to cause cancer, or birth defects or
other reproductive harm.
Health & Safety Code Section 25249.6 - Proposition 65

WARNING!

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
CLASS 1.
A specially instructed person should do servicing operation of the apparatus.

CAUTION

This product is a class 1 laser product classi­fied under the Safety of laser products, IEC
60825-1:2007, and contains a class 1M laser
module. To ensure continued safety, do not re­move any covers or attempt to gain access to
the inside of the product. Refer all servicing to
qualified personnel.

CAUTION—CLASS 1M INVISIBLE LASER
RADIATION WHEN OPEN, DO NOT VIEW
DIRECTLY WITH OPTICAL INSTRUMENTS.

Laser diode characteristics

Wave length : 785 nm to 814 nm
Maximum output : 1 190 µW(Emitting period : unlimited)

Additional Laser Caution

Transistors Q101 in PCB drive the laser diodes.
When Q101 is shorted between their terminals, the laser diodes will radiate beam.
If the top cover is removed with no disc loaded while such short-circuit is continued,
the naked eyes may be exposed to the laser beam.

CAUTION

Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacturer.
Discord used batteries according to the manufacturer's instructions.

1. You should conform to the regulations governing the product (safety, radio and noise, and other
regulations), and should keep the safety during servicing by following the safety instructions
described in this manual.

2. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors
during power-on mode may damage the ICs inside the unit.

3. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY".

4. After replacing the pickup unit, be sure to check the grating.

5. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by
electrostatic induction.

6. area and a heat sink becomes hot areas. Be careful not to burn yourself.

7. The RESET button is at the back of the Detach Grille.
Note that the audio settings cannot be deleted by a hard reset.
Reset the audio settings from the initial setting menu.

8. Be careful not to damage the Knob for the Slide Switches (S351, S601) at the bottom of the Tuner Amp Unit while
handling it or attaching the Bottom Plate.

9. The part listed below is difficult to replace as a discrete component part.

When the part listed in the table is defective, replace whole Assy.

10. RGB LED's (D1831 - D1864) are used for the illumination of the Keyboard Unit. To avoid the color heterogeneity, replace
the whole of the Keyboard Unit, even if only one of RGB LED's was defective.

1.2 NOTES ON SOLDERING

For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:
Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

Error Code

The error status occurs when CD/USB/SD cannot operate, or stop during operation due to an error.
The reason for such error is displayed with a numeral.
This intends to reduce the number of nonsense calls from users and to assist in analysis/repair in services.

1. Basic display method
An error status (F0h) is entered in the Media status area of the source concerned, and the code in the minute/second area for notification.

E.g. For Read Error
Media status (disc) = 0xF0h
Minute (upper): FFh
Minute (lower): 07h
Second: 07h

- As for VD ERROR, the error status shall be 0xFB.

- Example of head unit display

The following occurs depending on the LCD display capability. The error No. comes in xx.
* For OEM, the error shall be displayed as per the specification of the OEM destination.

Display in 8 digits

After the [EJECT] key is pressed keys other than the [EJECT] key should not be pressed, until disc ejection is complete.
When the key [UP] or [DOWN] is pressed during the Focus Search, the power supply should be immediately turned off (otherwise the
lens sticks to Wall, causing the actuator to be damaged).
In the case of 100TR Jump, the mechanism shall be set to the Tracking Close mode when the key is released.
When the power is turned on/off the gain of the RFAMP is reset to 0 dB. At the same time all the self-adjusting values shall return to the
default setting.
Do not do Tracking Servo Close before doing Focus Servo Close. (Because the overcurrent flows)
