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.

: 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!

• Pode ser utilizada com solda comum

E melhor usar apenas solda sem chumbo, mas este tipo també

pode ser adicionado a solda comum.

NATA SOBRE REPARO DO IC102 DA PLACA DMB19

IC102 da placa DMB19 não pode ser substituído individualmente.
Quando esta peça é com defeito, substitua a placa montada.

• 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.
