Cleaning the VX
820 DUET
To clean the unit, use a clean cloth slightly dampened with water and a drop or
two of mild soap. For stubborn stains, use alcohol or an alcohol-based cleaner.
For best results, use a Verifone Cleaning Kit (refer to the Accessories and
Documentation section).
Never use thinner, trichloroethylene, or ketone-based solvents – they can
deteriorate plastic or rubber parts.
Do not spray cleaners or other solutions directly onto the keypad or display.
