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.

CAUTION:

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

- 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.

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.

CAUTION

This product is a class 1 laser product classified under the Safety of laser products, IEC 60825-1:2007, and contains a class 1M laser module. To ensure continued safety, do not remove any covers or attempt to gain access to the inside of the product. Refer all servicing to qualified personnel.

CAUTION—CLASS 1M INVISIBLE LASER RADIATION WHEN OPEN, DO NOT VIEW DIRECTLY WITH OPTICAL INSTRUMENTS.

Laser diode characteristics

Wave length:

DVD:660 nm to 670 nm 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 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.

1.2 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).

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.

To keep the product quality after servicing, please confirm following check points.

No. Procedures Item to be confirmed

1 Confirm whether the customer complain has

been solved. If the customer complain occurs with the specific media, use it for the operation check.

The customer complain must not be reappeared. Display, video, audio and operations must be normal.

3 DVD Measure playback error rates at the

innermost and outermost tracks by using the test mode with the following disc. DVD test disc (TDV-582)

Deterioration of mecha-drive can be checked. The error rate must be less than the threshold value. (Refer to the chapter of DIAGNOSIS for the threshold value.)

4 DVD Play back a DVD.

(Menu operation; Title/chapter search)

Display, video, audio and operations must be normal.

5 CD Play back a CD.

(Track search)

Display, audio and operations must be normal.

6 FM/AM tuner Check FM/AM tuner action.

(Seek, Preset) Switch band to check both FM and AM.

Display, audio and operations must be normal. * If the reception sensitivity is poorer than normal, the gasket on the FM/AM tuner unit may be damaged or lost.

7 Check whether no disc is inside the product. The media used for the operating check must

be ejected.
