SAFETY INFORMATION
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 safety 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 safety, you should not risk trying to do so
and refer the repair to a qualified service technician.
This product is a class 1 laser product, but
this product contains a laser diode higher
than Class 1. To ensure continued safety,
do not remove any covers or attempt to
gain access to the inside of the product.
The following caution label appears on
your unit.
Location: on top of the cover
CAUTION: USE OF CONTROLS OR
ADJUSTMENTS OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.
CAUTION: THE USE OF OPTICAL
INSTRUMENTS WITH THIS PRODUCT
WILL INCREASE EYE HAZARD.
- 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.
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. You should conform to the regulations govering 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 about an internal sharp edge.
3. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by
electrostatic induction.
4. Be careful in handing made from metal parts. There might be burr at the edge of it.
5. Two kinds of resetting are available
1) Turn over the Detach Panel and press RESET Button at Central Part.
Without entire initialization.
Microcomputer restarting (emergency resetting at function trouble) .
With the reset of the pioneer.
2) Perform [Default Setting] initialization in Setting
Perform product initialization except a part of items.
Please carry it out when updating software.
6. Any component parts in the CD Mechanism Unit of this model can not be supplied.
If you need to replace any parts in the CD Mechanism Unit, replace whole of CD Mechanism Unit.
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.
