NOTAS DE SERVIÇOS
NOTAS SOBRE O MANUSEIO DA BLOCO DE UNIDADE Ó
O diodo laser da unidade optica e sensÍvel a descargas eletroestáticas podendo vir a ser danificado por descargas causadas por roupas ou mesmo pelo corpo humano. Durante o reparo tenha cuidado pa­ra não causar danos a unidade, devido a cargas eletroestáticas e siga corretamente os procedimentos descritos nesse manual para a exe­cução de reparos e troca de componentes. As placas de circuito impresso podem ser facilmente danificadas. Tenha cuidado ao manusea-las.
NOTAS SOBRE A EMISSÃO DO DIODO LASER
O feixe laser nesse modelo é concentrado e deve ser focado na super­ficie reflexiva do disco, pela lente objetiva da unidade optica. Quando estiver observando a emissão do diodo laser, tome o cuidado de estar no minimo a 30 cm da lente objetiva.
SOLDA SEM CHUMBO
Placas que exigem o uso de solda sem chumbo sã a marca LF (lead free) indicando que a solda não contem chumbo. (Atenção

: IDENTIFICAÇÃO DA SOLDA SEM CHUMBO
A solda livre de chumbo tem as seguintes caracteristicas:
Derrete a uma temperatura 40 °C maior que a solda comum.
Ferros de solda comuns podem ser usados mas a ponta tem que
ser aplicada sobre a solda por um tempo maior.
Ferros de solda com ajuste de temperatura devem ser ajustados
no valor de 350 °C. Atenção: A impressao da placa (trilhas de cobre) pode se soltar
se a ponta permanecer por muito tempo. Tenha cuidado!

E melhor usar apenas solda sem chumbo, mas este tipo també
pode ser adicionado a solda comum.

MODO DE TESTE

[GC TEST MODE]
• This mode is used to check the fl uorescent indicator tube, LEDs, keys, VOLUME jog, OPERATION DIAL jog, model, destination and software version.
Procedure:
1. Press [x] button, [ENTER] button and [DISC 2] button si-
multaneously.
2. All LEDs and segments in fl uorescent indicator tube are light-
ed up. All LEDs are lighted up in red color except for [ LED where the LED is lighted up in red and blue color,
[ A] LED in blue color and SUBWOOFER ON/OFF in
green color.
3. When you want to enter to the model version and destination
display mode, press [DISC 1] button. The model information appears on the fl uorescent indicator tube.
4. Each time [DISC 1] button is pressed, the display changes to
display software version and date of the software creation. The sequence is model destination, SC, MDK, GC, SYS, CD, CDMA, CDMB, ST, TC, TA, TM and MTR in this order, and returns to the model destination display.
5. Press [DISC 2] button, the key check mode is activated.
6. In the key check mode, the fl uorescent indicator tube displays
“K 0 J0 V0”.
Turn the [OPERATIONAL DIAL] clockwise; ”J” value in-
creases by one. Turn the [OPERATIONAL DIAL] counter­clockwise; “J” value decreases by one. Each time a button is pressed, “K” value increases. Press other keys on main unit to check whether the key is detected. However, once a button has been pressed, it is no longer taken into account.
“V” value increases in the manner of 0,1, 2, 3 ... if [VOLUME]
knob i s tu rned clock wis e, or it d ecr eas es i n th e ma nne r of 0 , 9, 8, 7 ... if [VOLUME] knob is turned counterclockwise.
7. When [DISC SKIP/EX-CHANGE] button is pressed after
all LEDs and segments in fl uorescent indicator tube light up, alternate segments in fl uorescent indicator tube and LED would light up. If you press [DISC SKIP/EX-CHANGE] but­ton again, another half of alternate segments in fl uorescent indicator tube and LED would light up. Press [DISC SKIP/ EX-CHANGE] button again would cause all segments will lights off and press [DISC SKIP/EX-CHANGE] button again all segments will lights up.

• Note For Printed Wiring Boards And Schematic Diagrams
Note on Printed Wiring Board:
X : parts extracted from the component side.
Y : parts extracted from the conductor side.
: Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
Caution: Pattern face side: Parts on the pattern face side seen from (Conductor Side) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (Component Side) the parts face are indicated.
Indication of transistor.
A : B+ Line.
B : B– Line.
• Voltage and waveforms are dc with respect to ground under no-signal (detuned) conditions.
• BD93 and Driver sections. no mark : CD PLAY
• Except BD93 and Driver sections. no mark : FM ( ) : CD PLAY < > : TAPE PLAY [ ] : TAPE REC
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 M:).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : AUDIO f : TUNER
N : MIC J : CD PLAY c : DIGITAL I : USB
Note: The components identifi ed by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specifi ed.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to fl ow) than
ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may also
be added to ordinary solder.
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.
• All resistors are in : and 1/4W or less unless otherwise specifi ed.
2 : nonfl ammable resistor.
C : panel designation.
