The top of the touchscreen is a thin, flexible polyester plastic sheet with a conductive

is susceptible to abrasions and scratches. NEO is equipped with a stylus that is designed

sharp objects on the touchscreen can scratch or cut the plastic, or crack the internal
conductive coating.
The chemicals listed below must not come into contact with the touchscreen:
• sodium hydroxide,
• concentrated caustic solutions,
• benzyl alcohol, and
• concentrated acids.
Note: An optional protective cover (PN 1081366) is available to help protect the touch-
screen. Follow the installation instructions shipped with the cover.
