8 Maintenance 

and 

Service 

 

CAUTION 

There are no user serviceable parts inside the Model 500B Series 
Laser Diode Drivers.  Work performed by persons not authorized 
by Newport Corporation will void the warranty.  

8.1 Enclosure 

Cleaning 

 

 

WARNING 

Before cleaning the enclosure of the Model 500B Series Laser 
Diode Drivers, the AC power cord must be disconnected from 
the wall socket.   

The source enclosure should only be cleaned with a mild soapy water 
solution applied to a damp lint-free cloth.  Do not use an acetone or alcohol 
solution; this will damage the finish of the enclosure.
