4. General Maintenance
4.1 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.
If the touchscreen is used in harsh environments, consider applying a
disposable screen protector (PN 1008009). These covers reduce the
clarity of the display slightly but will dramatically extend the useful
life of the touchscreen. When they become scratched and abraded,
they are easily removed and replaced.
The chemicals listed below must not come into contact with the
touchscreen:
• mustard, ketchup,
• sodium hydroxide,
• concentrated caustic solutions,
• benzyl alcohol, and
• concentrated acids.

•Use only mild detergent or soapy water to clean the vehicle-
mount unit.
• Avoid abrasive cleaners, solvents or strong chemicals
for cleaning.
• To clean ink marks from the keypad and touchscreen, use iso-
propyl alcohol.
