Descrição do Erro

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

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

Erro de Entrada do SledgeO 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.

Erro de Saída do SledgeO sledge não saiu de sua posição interna (chave interna permanece aberta) antes que250 mSec. tenha passado. Problema na chave interna ou no motor sledge.

Erro Jump-offtrackDisparado 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 sucedidoo disco continuará a ser reproduzido.

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

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

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

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

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

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

A gaveta não pôde entrar na posição interior e poderia estar abrindo novamente. Isto acontecequando a gaveta é bloqueada e não pode fechar inteiramente ou quando a chave da gaveta estádefeituosa e não fecha.
