Labels 
Each MS7580 has a label located near the top of the output window.  This label 
provides the imager’s model number, date of manufacture, serial number, CE 
and caution information.  Additional information has been molded into the 
underside of the imager's case.  The following figure gives an example of the 
label and the molded text with their locations identified.

Maintenance 
Smudges and dirt on the imager's window can interfere with the imager's 
performance.  If the window requires cleaning, use only a mild glass cleaner 
containing no ammonia.  When cleaning the window, spray the cleaner onto a lint 
free, non-abrasive cleaning cloth and then gently wipe the window clean.  
If the imager's case requires cleaning, use a mild cleaning agent that does not 
contain strong oxidizing chemicals.  Strong cleaning agents may discolor or 
damage the imager's exterior.
