General Maintenance  

The subsequent sections describe how to maintain the Product.  

Clean the Exterior 

Clean the case, front panel keys, and display with a soft cloth slightly dampened 

with either water or a non-abrasive mild cleaning solution that is not harmful to 

plastics.  

Caution 

Do not use aromatic hydrocarbons or chlorinated solvents for 

cleaning. They can damage the plastic materials used in the 

Product.  

Fuse Replacement 



Warning 

To prevent possible electrical shock, fire, or personal injury:  

•

 

Turn the Product off and remove the mains power cord. 
Stop for two minutes to let the power assemblies discharge 
before you open the fuse door. 

•

 

Use only specified replacement fuses. 

Access the fuse from the rear panel. The fuse rating label located under the fuse 

holder shows the correct replacement fuse ratings for each operating voltage. To 

access the fuse, refer to Figure 2020:  
1.  Disconnect line power. 
2.  With a standard screwdriver, release the fuse holder door. 
3.  Pull out the fuse holder. 
4.  Replace the fuse. Replacement fuses are listed in Table 25. 
5.  Reinsert the fuse holder. 
6.  Close the fuse holder door.
