Health & Safety Code Section 25249.6 - Proposition 65

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:

- 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.
D
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.

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

CAUTION
E This product is a class 1 laser product classi-
fied under the Safety of laser products, IEC
60825-1:2007, and contains a class 1M laser

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.

Laser diode characteristics
Wave length:
DVD:660 nm to 670 nm B
CD:780 nm to 800 nm
Focus lens on Maximum output:
CD:6.26 mW(Emitting period :9 sec.)
DVD:1.27 mW (Emitting period : unlimited)

Additional Laser Caution

Transistors Q1103 and Q1104 in PCB drive the laser diodes for DVD and CD
respectively. When Q1103 or Q1104 is shorted between their terminals,
the laser diodes for DVD or CD will radiate beam. If the top cover is removed C
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 manufacture.
Discord used batteries according to the manufacture's instructions.

1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
A

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. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
3. Please be sure to conduct line process to original status if you make assembling after repair.
4. Please be careful of not to imply static charge onto integrated circuits, etc, when you conduct repair work.
Especially, please use soldering iron with its tip grounded.
Also, please use a pair of tweezers with static charge protection capability if there is the possibility of contacting to
device terminals, and avoid the use of metal-made tweezers.
5. 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. B
6. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder)
by referring to "the DISASSEMBLY".
7. Please keep the distance of more than 13 cm from focus lens for safety when you check pickup and make adjustment,
and do not look straight at Laser Beam for more than 10 seconds.
8. Please power adjustment when you replaced mechanical area of DVD Mecha Module or DVD core unit.
9. Graphically-illustrated areas become hot . Be careful not to burn yourself.

10. The acceptance surface of the remote controller on the keyboard PCB is not fixed with a cushion or other materials.
External force applied on the acceptance surface of the remote controller may distort the lead and change the mounting
angle of the acceptance surface, and accordingly, deteriorate the light sensitivity.
Do not apply external force on the acceptance surface of the remote controller.
If you accidentally apply external force, check whether the lead is bent or not.
If the lead is bent, repair it so that the angle between the lead and the acceptance surface becomes 90 degrees, or
exchange the acceptance surface for the remote controller (PNJ4833M).
11. When a home product is used in a vehicle (using DC/AC converter), GND on secondary side of some devices of home
products (PS etc.) becomes indefinite. If these devices are connected to AVH, GND becomes indefinite because ISO is
E
received and the video disordered.
If a defect is generated in a market, the land is prepared between GNDs for connecting GND of AVH sides and VGND
of input as a service.
With this product, a part of VGND pattern is thin. If it is used, insert 0.5A of fuse.
A used part and wiring numbers are shown below.
Wiring number: P531, P532
Used part: CEK1379 or CEK1278
12. 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.

13. On this mechanism, Pickup and Spindle Motor can not be replaced at the service site, because a special facility is
required for the adjustment after replacing them.
So, if Pickup or Spindle Motor is defective, replace the Mechanism Unit.

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).
B

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.
