cut the plastic, or crack the internal conductive coating.
Protect the touchscreen from the following chemicals:
• mustard, ketchup etc.,
• sodium hydroxide,
• concentrated caustic solutions,
• benzyl alcohol, and
• concentrated acids.
If touchscreens are used in harsh environments, apply disposable
screen protectors (PN HU6110). They reduce the clarity of the dis-
