Инструкция по эксплуатации системы для работы с полупроводниковыми пластинами 

Do not remove covers or defeat electrical or mechanical interlocks on the system.  

Only trained personnel should defeat interlock switches. 

When the interlocks are defeated, lasers can be present.  

Maintenance of the laser with interlocks defeated and the laser exposed requires that a laser safety area be set up around the the system. 

Do not defeat safety interlocks unless specifically required to do so for a service procedure you are trained to perform
