Cleaning 

 

To maintain the visual appearance of your AP990C, occasionally wipe the front 

panel and top cover surfaces with a soft damp (not wet) cloth to remove dust. A 
mild, non-alkaline soap solution may be used to remove fingerprints or similar 

smudges. Cleaners containing abrasives should not be used as they will damage  
the brushed grain of the front panel finish.
