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. 

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. 

O uso dos controles, ajustes ou execução de procedimentos 
que não sejam os descritos nesse manual, podem causar exposição 
a uma perigosa radiação. 

 Nunca reutilize um componente tipo chip. 
• Informamos que os capacitores eletrolíticos de tântalo podem 

ser danificados se expostos a altas temperaturas. 

• 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.
