2.1 Instruções de Segurança

2.1.1 Segurança geral

As normas de segurança requerem que durante um reparo:

• Conecte a unidade aos cabos principais um transformador

de isolamento.

• Recoloque os componentes de segurança, indicados pelo sím-

bolo

, somente pelos componentes idênticos aos originais.

Qualquer outra substituição de componente (com exceção

do tipo original) pode aumentar o risco de fogo ou choque

elétrico.

As normas de segurança requerem que depois de um

reparo, você deve retornar a unidade na sua condição original.

Preste atenção, particularmente, nos seguintes pontos:

• Distribua os fios e cabos corretamente, e separe-os com os

suportes de montagem de cabos.

• Verifique se não há danos na isolação dos fios da rede elétrica.

• Verifique a resistência elétrica DC entre os fios do plugue de

rede e o lado secundário:

Desplugue o cabo de rede, e conecte um fio entre os

dois pinos do cabo de rede.

Ajuste os fios do interruptor de rede na posição “ON”

(mantenha o cabo de rede desplugado!)

Meça o valor da resistência entre os pinos do cabo de força

e o painel frontal, botões de controle e chassis.

O produto reparado está normal quando a resistência

medida é de mais de 1 MΩ.

Verifique isto, antes de retornar o produto ao cliente / usuá-

rio (ref. UL- padrão no. 1492).

Mude o produto para “OFF”, e remova o fio entre os dois

pinos do plugue de força.

2.1.2 Segurança de laser

Essa unidade emprega um laser. Somente pessoal de serviço

qualificado pode remover a tampa, ou tentar prestar serviços de

manutenção nesse dispositivo (devido a possível danos aos

olhos).

Unidade do dispositivo de Laser

Tipo: laser semi-condutor GaAlAs

Comprimento de onda: 650 nm (DVD)

780nm (VCD/CD)

Potência de saída: 20 mW (DVD+RW writing)

: 0.8 mW (leitura de DVD)

: 0.3 mW (leitura de VDC/CD)

Divergência do feixe: 60 graus

Figura 2-1

Nota:

o uso dos controles ou do ajuste ou o desempenho do pro-

cedimento à exceção daqueles especificado neste manual, podem

resultar na exposição perigosa à radiação. Evite a exposição direta

ao feixe.

2.2 Cuidados

2.2.1 Geral

• Todos os CIs e muitos outros semicondutores são suscetí-

veis as descargas eletrostáticas (ESD,

) a manipulação

descuidada durante o reparo pode reduzir a vida drasticamente.

Certifique-se que durante o reparo, você está no mesmo

potencial que a terra do aparelho por uma pulseira com resis-

tência. Mantenha os componentes e ferramentas na mesma

potência.

Equipamentos de proteção disponíveis ESD:

- Kit completo ESD3 (pequenas TABLEMAT, WRISTBAND, caixa

de conexão, cabo de extensão e fio terra) 4822 310 10671.

- Verificador Wristband 4822 344 13999

• Tenha cuidado durante a medida na seção viva da tensão. O

lado primário da fonte de energia (pos. 105), incluindo o dissi-

pador de calor, carrega a tensão viva dos fios de rede quando

você conecta o aparelho na rede elétrica (mesmo quando o

aparelho está desligado!). É possível tocar nas trilhas e nos

componentes de cobre nesta área preliminar desprotegida,

quando você prestar serviços de manutenção no aparelho.

O pessoal de serviço deve tomar precauções para evitar tocar

esta área ou em componentes desta área. Um “lightning stroke”

é uma listra marcada impressa no painel de fiação, indica o lado

preliminar da fonte de alimentação.

• Nunca substitua módulos ou componentes enquanto o produto

estiver ligado.

2.2.2 Laser

• O uso de instrumentos ópticos com este produto irá aumentar o

perigo de danos aos olhod.

• Apenas o pessoal de serviço qualificado pode remover a tampa

ou tentar prestar serviço de manutenção a esse dispositivo,

devido a possível danos aos olhos.

• A manipulação do reparo deve ocorrer tanto quanto possível

com um disco carregado dentro do aparelho

• O texto abaixo é colocado dentro da unidade, no protetor de

tampa do laser:

Safety Information, General Notes & Lead Free Requirements

2.1 Safety Instructions

2.1.1 General Safety

Safety regulations require that during a repair:

• Connect the unit to the mains via an isolation transformer.

• Replace safety components, indicated by the symbol

only by components identical to the original ones. Any

other component substitution (other than original type)

may increase risk of



re or electrical shock hazard.

Safety regulations require that after a repair, you must return

the unit in its original condition. Pay, in particular, attention to

the following points:

• Route the wires/cables correctly, and

 x them with the

mounted cable clamps.

• Check the insulation of the mains lead for external

damage.

• Check the electrical DC resistance between the mains

plug and the secondary side:

1. Unplug the mains cord, and connect a wire between

the two pins of the mains plug.

2. Set the mains switch to the ‘on’ position (keep the

mains cord unplugged!).

3. Measure the resistance value between the mains

plug and the front panel, controls, and chassis

bottom.

4. Repair or correct unit when the resistance

measurement is less than 1 Mȍ.

5. Verify this, before you return the unit to the customer/

user (ref. UL-standard no. 1492).

6. Switch the unit ‘off’, and remove the wire between the

two pins of the mains plug.

2.1.2 Laser Safety

may remove the cover, or attempt to service this device (due

to possible eye injury).

2.2 Warnings

2.2.1 General

• All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD, ). Careless handling

during repair can reduce life drastically. Make sure that,

during repair, you are at the same potential as the mass

of the set by a wristband with resistance. Keep

components and tools at this same potential.

Available ESD protection equipment:

– Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable and earth cable)

4822 310 10671.

– Wristband tester 4822 344 13999.

• Be careful during measurements in the live voltage

section. The primary side of the power supply, including

the heatsink, carries live mains voltage when you

connect the player to the mains (even when the

player is ‘off’!). It is possible to touch copper tracks and/

or components in this unshielded primary area, when

you service the player. Service personnel must take

precautions to prevent touching this area or components

in this area. A ‘lightning stroke’ and a stripe-marked

printing on the printed wiring board, indicate the primary

side of the power supply.

• Never replace modules, or components, while the unit is

‘on’.

2.2.2 Laser

• The use of optical instruments with this product, will

increase eye hazard.

• Only quali



ed service personnel may remove the cover or

attempt to service this device, due to possible eye injury.

• Repair handling should take place as much as possible

with a disc loaded inside the player.
