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 mes­
mo 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 exe­
cução de reparos e troca de componentes. As placas de circuito im­
presso são facilmente danificadas, tenha muito cuidado para manu­
seá-las. 
NOTAS SOBRE O DIODO EMISSOR DE LASER 
O feize laser nesse modelo é concentrado e deve ser focado na super­
fície reflexiva do disco, pela lente objetiva da unidade óptica. Quan­
do observar a emissão do diodo laser, tome o cuidado de estar 
no mínimo a 30 cm da lente objetiva. 
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 270ûC 
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.
