Cleaning the LED Touch Screen and External Surfaces of the Analyzer
The screen protector shields the touch screen surface from dirt and spills while maintaining the screen’s
responsiveness and functionality. The screen protector film should be replaced every 6 months.
Clean the analyzer’s LED touch screen using a soft, lint-free cloth and lens cleaner solution containing a
mixture of alcohol and water. Gently wipe down the screen until any visible fingerprints, smudges, dust or
other signs of contaminants are gone.
Clean the external surface of the analyzer with a soft, damp cloth.
