Cleaning the Analyzer
You can clean the external housing of the Analyzer with a damp cloth using water or non-abrasive cleaners. 
Turn off power to the Analyzer and disconnect it from main power prior to cleaning. Do not spray liquids directly 
on the Analyzer. Wipe dry with a clean, soft cloth.
The touchscreen may be cleaned with a soft cloth or cotton pad lightly applied with a spray cleaner. Isopropyl 
Alcohol may be used, but ensure that all solvent residue is removed. Water may cause damage or discoloration 
of the polarizer. Clean any condensation or moisture from any source immediately. Before cleaning the screen, 
you can temporarily deactivate touchscreen sensitivity for 30 seconds.
To deactivate the screen
