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.
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 manufacturer.
Discord used batteries according to the manufacturer'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.

2. MCU software update
3. BT software update (Only a model with BT functional)
4. Reset, "do default setting" in the setting menu.
5. Check Version
Insertion of USB will display the following Update screen.
UW model
Method of individual upgrading
Prepare files shown below according to the purpose for upgrading the software. (It is not necessary to prepare all files)
Item to upgrade Use software
MPEG build.img , UPD_MPEG.VER
MCU update.img , UPD_MCU.VER
BT NFOREBT.dfu , UPD_BT.VER
Upgrade the software in the order of MPEG, MCU, and BT.
Please be sure to perform Default Settings in the Setting after performing Version Up.
If you do not perform the Version Up, the initialization of MPEG software will not be executed.
In addition, the Main Body Reset SW located at the rear surface of Detach Panel is only for the Restart RESET
of MCU and it does not mean to perform all of the initializations.

1. MPEG update instruction
1. Copy the MPEG update files(upd_mpeg.ver, build.img) to USB device, and insert it to USB Port,
when the system detect the update file exists, it will pop up a menu like Fig.1 as below:
UW5 modelBR model
Fig.1-1Fig.1-1
2. If you don’t want to upgrade ,you can press “Cancel” button through Left or Right key of remote control or panel,
otherwise you can move the curse to button “MPEG”, and after pressing Enter key, there will pop other prompt
menu like Fig.2, as below:
UW5 modelBR model
Fig.2-1Fig.2-1
3. During the process of upgrade, do not remove the USB device or shut off the power supply, otherwise the system
will breakdown, and never recover any more, if the system restart and pop up Fig.1 for the second time, it means
MPEG upgrade process finished, you can remove the USB device, the whole upgrade process will last about 1 minute;

3. After erasing process finish, system start to upgrade process, and you will find the upgrade process,
just like Fig.5 as below:
4. During the process of upgrade, it’s allowed the user to remove the USB device, because system had copied the
update files to SDRAM, this is different from MPEG upgrade, after the process reach 100%, which means MCU
upgrade finished, and the system will power off automatically, you need to press the power key to restart the system,
the whole upgrade process will take around 2.5 Minutes

2. MCU update instruction
1. Copy the MCU update files(UPD_MCU.VER, update.img) to USB device, and insert it to USB port,
when the system detect the update file exists, it will pop up a menu like Fig.3, as below:
