1. SERVICE PRECAUTIONS

1.1 SERVICE PRECAUTIONS

A

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.)

BConduct 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.

C6. 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.

1.2 NOTES ON SOLDERING

A

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.

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
D	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.
