NOTAS SOBRE O MANUSEIO DA UNIDADE ÓP TICA
O diodo laser da unidade óptica é sensível a descargas eletroestáticas
podendo 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 descargas eletroestáticas e siga
corretamente os procedimentos descritos nesse manual para a execução de reparos e troca de componentes. As placas de circuito impresso são facilmente danificadas, tenha muito cuidado para manuseá-las.
NOTAS SOBRE O DIODO EMISSOR DE LASER
O feize laser nesse modelo é concentrado e deve ser focado na superfície reflexiva do disco, pela lente objetiva da unidade óptica. Quando observar a emissão do diodo laser, tome o cuidado de estar
no mínimo a 30 cm da lente objetiva.
O componente laser desse produto é capaz
de emitir radiação, excedendo o limite da
Classe 1.
Este aparelho é classificado como um produto LASER CLASSE 1.
O símbolo do produto laser classe 1 está localizado na parte posterior
externa do aparelho.
Atenção
O uso dos controles, ajustes ou execução de procedimentos
que não sejam os descritos nesse manual, podem causar exposição
a uma perigosa radiação.
Notas sobre substituição de componentes tipo chip
• Nunca reutilize um componente tipo chip.
• Informamos que os capacitores eletrolíticos de tântalo podem
ser danificados se expostos a altas temperaturas.
Notas sobre o reparo da placa de circuito impresso
• Mantenha a temperatura do ferro de solda por volta de 270˚C
durante o reparo.
• Não ressolde componentes em um mesmo ponto da placa mais
de três vezes.
• Tenha cuidado para não forçar os condutores (trilhas) da placa
durante o processo de soldagem e dessoldagem.
SAFETY-RELATED COMPONENT WARNING!!

ÍNDICE
VERIFICAÇÃO DE SEGURANÇA
Depois de corrigido o problema de manutenção original, execute as seguintes verificações de segurança antes de liberar o aparelho para o consumidor: verifique os terminais de antena, o acabamento metálico, os botões "metalizados", os parafusos e outras peças de metal expostas, para verificar se não há fuga AC:
FUGA
A fuga de AC de alguma parte do metal exposta à terra e de todas as
partes de metal expostas que tenham retorno ao chassi, não deve
exceder 0,5mA (500 micro-amperes). A corrente de fuga pode ser
medida por qualquer um dos três métodos abaixo:
1.
Um aparelho medidor de fuga, como o Simpson 229 ou o RCA
WT-540A. siga as instruções dos fabricantes para usar esses instrumentos.
2.
Um miliamperímetro operado a bateria. O multímetro digital
Data Precision 245 é adequado para esse serviço.
3.
Medindo a queda de tensão através de um resistor por meio
de um multímetro ou de um voltímetro de AC operado a bateria.
A indicação de limite é de 0,75 V, desse modo os medidores
analógicos precisam ter uma escala precisa de baixa tensão. O
Simpson 250 e o Sanwa SH-63Trd são exemplos de multímetros operados a bateria, que têm uma faixa de 2V AC, são
adequados.

MODO DE TESTE
[MC Cold Reset]
• O cold reset limpa todos os dados, imcluindo os armazenados
na RAM ao inicializar o aparelho. Execute este modo quando for
devolver o aparelho ao cliente.
Procedimento:
1. Aperte os botões x , ENTER , e ?/1 simultaneamente.
2. O tubo fluorescente mostrará “COLD RESET” e o
modo terá sido executado.
[CD Ship Mode]
• Este modo move a unidade para uma posição segura para o
transporte. Execute-o quando for devolver o aparelho ao
cliente.
Procedimento:
1. Tecle 1/u para ligar o aparelho.
2. Tecle CD junto com 1/u (simultâneamente).
3. Depois do "STANDBY" piscar seis vezes, a mensagem
“LOCK”é mostrada no tubo fluorescente, então
o aparelho estara no CD Ship Mode.
[MC Hot Reset]
• Este modo limpa a memória, eliminando todos os dados e
programações armazenados, algo similar a desligar o cabo de
alimentação da tomada e reconectá-lo depois.
Procedimento:
1. Tecle os botões x , ENTER , e DISC 1 simultaneamente.
2. O tubo fluorescente apagara por um instante e a memória
do aparelho estará limpa.
[CD Service Mode]
• Este modo permite que o CD Sled Motor corra livrimente.
Use-o para limpar a unidade.
Procedimento:
1. Tecle ?/1 para ligar o aparelho.
2. Selecione a função “CD”.
3. Tecle os botões x , ENTER , e OPEN/CLOSE simultaneamente.
4. O Modo CD Service é selecionado.
5. Com o CD parado, gire o knob shuttle no sentido horário para
mover a unidade para fora e no sentido anti-horário para
mover a unida para dentro.
6. Para sair deste modo faça o seguinte:
1) Mova a unidade para a posição da faixa mais interna.
2) Pressione os botões do passo 2 de forma analoga.
Nota: • Sempre posicione a unidade na posição da faixa mais interna para
sair deste modo. Do contrário, um disco não poderá ser lido.
• Não use (mova) o sled motor excessivamente, pois pode causar o
desgaste das engranagens.
MHC-DX20
[Variando o passo do AM entre 9 kHz e 10kHz]
10 kHz]
• O passo de seleção de frequência do AM pode ser de 9kHz
ou de 10 kHz.
Procedimento:
1. Tecle ?/1 para ligar o aparelho.
2. Selecione a função “TUNER”, e tecle TUNER/BAND
para selecionar a faixa “MW”.
3. Press ?/1 button to turn the set OFF.
4. Tecle ENTER e ?/1 simultaneamente, e o display fluorescente indicará “MW 9 k STEP” ou “MW 10 k STEP”.
O valor indicado será o novo passo nesta faixa.
[GC Test Mode]
• Este modo é usado para verificar a versão de software, o tubo FL, os
LED"s, as teclas e os VACS.
Procedimento:
1. tecle os botões x , ENTER , e DISC 2 simultaneamente.
2. Todos os LED's e o todo otubo fluorescente acendem.
3. Para visualizar o mode de exibição da vesão do software,
tecle DISC 1 . O número do modelo e o destino serão exibidos.
4. Sempre que DISC 1 é apertado, a sequência de exibição começa:
versão do MC, versão do GC, versão do VC, versão do CD, versão
do CM, versão do ST, versão do TC, versãoo do TA, versão do TM e
versão do BRnesta ordem, e retorna ao número do modelo e
e o destino.
5. Tecle DISC 3 e uma sequência de números começará a ser exibida, exceto o número do modelo e o destino. São mostrados o
ano, o mês, e o dia da criação do software. Quando DISC 3 é
teclado novamente, o display retorna à versão do software.
Tecle DISC 1 enquanto aparece o ano, o mês e o dia da criação
do software e aparecerá o ano, o mês e o dia da criação
da versão do software,sendo exibida na mesma ordem que a já
exibida anteriormente.
6. Tecle DISC 2 e o modo de verificação das chaves é ativado.
7. No mode de verificação das chaves, o tubo fluorescente mostrará
“KEY0 VOL0”. Cada vez que um botão for precionado, o valor de
“KEY”aumenta, todavia, uma vez que um botão foi apertado
ele não voltará a ser contado.
O valor do “VOL” aumenta de 1, 2, 3 ... se rodado o VOLUME
no sentido “+” ou decresce de 0, 9, 8 ... se rodado no
sentido “–”.
8. Quando DISC 3 é pressionado depois de todos os LEDs e do
tubo fluorescente acenderem, aparece o valor dos VACS.
9. Para sair deste modo pressione as três teclas indicadas
no passo 1 ou desconecte o cabo de alimentação da tomada.
[VACS ON/OFF Mode]
• Este modo é usado para chavear o VACS (Variable Attenuation
Control System) em ON ou OFF.
Procedimento:
Pressione ENTER e SPECTRUM simultaneamente. A mensagem “VACS OFF” ou “VACS ON” aparecerá no display.
14
MHC-DX20
[MC Test Mode]
• Este modo é utilizado para verificar as operações das seções
do amplificador, do tuner, do CD e do toca-fitas.
Procedimento:
1. Pressione ?/1 para ligar o aparelho.
2. Pressione os botões
x , ENTER e DISC 3
simultaneamente.
3. A messagem “TEST MODE” aparecerá no tubo FL
4
Tecle f (CURSOR UP) e o GEQ vai para o valor máximo

Este modo é utilizado para verificar o funcionamento da CD e do toca-fitas
• Se um erro ocorrer:
A operação de aging para e aparece uma mensagem.
• Se não ocorrer nenhum erro:
A operação de aging será repetida continuamente.
1. Método de operar o modo de aging
Ligue o aparelho e selecione a função "CD".
1) Selecione o DISC1. Selecione ALL DISC CONTINUE, e REPEAT OFF.
2) Carregue uma fita no deck A e outra no deck B.
3) Tecle os botões x , ENTER , e
DISC SKIP/EX-CHANGE simultaneamente.
4) A operação de aging do CD é inicializada depois de algum tempo.
5) Para sair do modo de aging, execute o [MC Cold Reset].

2) Operação durante o modo de aging
No modo de aging, o programa é executado na seguinte sequequência.
(1) A bandeja de discos abre e fecha.
(2) O mecanismo acessa o DISC 2 e faz uma tentativa de ler
TOC. Toda via, se não houver discos, a menssagem
“CD2 NO DISC” aparecerá.
(3) O mecanismo acessa o DISC 3 e a menssagem “CD3 NO
DISC” aparece.
(4) A bandeja seleciona o DISC 1.
(5) Um disco é carregado.
(6) O TOC do disco é lido.
(7) A unidade acessa a faixa 1 e a executa por 2 segundos.
(8) A unidade acessa a última faixa e a executa por 2 segundos.
(9) Toda vez que se completar uma operação do aging (passos 1 a 8)
o display indicará “AGING[*][*][*][*]” aumentando o
valor do número de operações realizadas.
