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. DEMO MODE is activated by Default Setting.
Keys other than followings are not accepted under DEMO MODE operation.
[SRC], [ESC] and [POWER] (However, POWER being OFF in case of POWER Key.)

Conduct performance confirmation after releasing DEMO MODE operation temporarily.

How to perform temporary releasing
DEMO operation is released temporarily with [SRC] or [ESC] Key on Main Body Key (or on Remote Controller) and
normal operation becomes possible.

How to make DEMO MODE to be OFF (There are two ways, (1) and (2))
DEMO MODE under operation
(1) Turn ACC from OFF to ON. This makes DEMO setting to be OFF.
(2) Temporarily release DEMO MODE (by pressing [SRC] or [ESC] Key) and change setting of DEMO in GENERAL
from setting menu by changing ON to OFF.

6. 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.

7. Any component parts in the DVD Mechanism Unit of this model can not be supplied.

If you need to replace any parts in the DVD Mechanism Unit, replace whole of DVD Mechanism Unit.

8. Graphically-illustrated areas become hot. Be careful not to burn yourself.

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.

6.2 SOFTWARE VERSION UP METHOD

Save six (6) sorts of file for Version Up (build.img, UPD_MPEG.VER, update.img, UPD_MCU.VER, UPD_BT.VER and
NFOREBT.dfu) on an USB.
Turn the product power to be ON and insert the above mentioned USB.

1. MPEG software update

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.

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
