JAZZ & TECHNO são ligados enquanto OPTIMAL está desligado, outros status de LED's não são importantes (aplicável apenas para aparelhos com LED's).

Figura 1

Display mostra a Fig. 1 e acende todos os LEDs (exceto ECO, Power e Volume) e deflexão total do VU

O modo de serviço Play é destinado a detectar e identificar falhas no modo CD. 2 Botão pressionado?

Neste modo a parte eletrônica continua funcionando mesmo que um erro seja detectado, desta forma é possível realizar o conserto.

Cód. de Erro E1000

Descrição do Erro

9 Botão pressionado?

Erro de Foco Disparado quando o foco não pode ser obtido após um certo tempo ao iniciar o CD ou quando o foco é perdido por um certo tempo durante a reprodução.

E1001

Erro Radial Disparado quando o servo radial perde a trilha por um certo tempo durante a reprodução.

E1002

Erro de Entrada do Sledge O sledge não alcançou sua posição interna (chave interna permanece fechada antes que 6 seg. 6 Sec. tenha passado. Problema na chave interna ou no motor sledge.

E1003

Erro de Saída do Sledge O sledge não saiu de sua posição interna (chave interna permanece aberta) antes que 250 mSec. tenha passado. Problema na chave interna ou no motor sledge.

E1005

Erro Jump-offtrack Disparado na reprodução normal quando o salto para um destino não pode ser alcançado. Quando este erro ocorre, o software tentará reiniciar o comando de salto. Se não bem sucedido o disco continuará a ser reproduzido.

E1006

Erro de Sub Código Disparado quando um novo Sub Código é perdido durante um certo tempo na reprodução

E1007

Erro de PLL O Phase Lock Loop (PLL) não consegue travar durante um certo tempo.

E1008

Erro na Plataforma Giratória Gerado quando o CD não alcança 75% da velocidade durante a inicialização. Problema no motor do disco.

E1020

Erro na Busca de Foco (Focus Search) O ponto do foco não pode ser encontrado após um certo tempo.

E1070

A chave Carrossel não abre após um certo tempo. Isto pode acontecer quando a chave está defeituosa e sempre fechada, ou quando o carrossel é bloqueado na posição exata de um disco.

E1071

A chave Carrossel não fecha após um certo tempo. Isto pode acontecer quando a chave está defeituosa e sempre aberta, ou quando o carrossel é bloqueado na posição entre dois discos. O tempo limite é de aproximadamente 5 segundos.

E1079

A gaveta não pôde entrar na posição interior e poderia estar abrindo novamente. Isto acontece quando a gaveta é bloqueada e não pode fechar inteiramente ou quando a chave da gaveta está defeituosa e não fecha. Tabela 2
