5.1 Caring For The Touchscreen
The top of the touchscreen is a thin, flexible polyester plastic sheet
with a conductive coating on the inside. The polyester can be perma-
nently damaged by harsh chemicals and is susceptible to abrasions
and scratches. Using sharp objects on the touchscreen can scratch or
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-
play slightly but will dramatically extend the life of the touchscreen.
When they become damaged, they are easily removed and replaced.
