3.11 General Maintenance
3.11.1 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 permanently damaged by harsh chemicals and
is susceptible to abrasions and scratches. NEO is equipped with a stylus that is designed
to safely select items on the touchscreen. Use only the stylus on the touchscreen; using
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.
3.11.2 Cleaning NEO
•Use only mild detergent or soapy water to clean the hand-held unit.
• Avoid abrasive cleaners, solvents or strong chemicals. The plastic case is susceptible to
harsh chemicals; it is partially soluble in oils, mineral spirits and gasoline. The plastic
slowly decomposes in strong alkaline solutions.
• To clean ink marks from the keyboard and touchscreen, use isopropyl alcohol.
• When using a dampened cloth to clean NEO, make certain that the battery cover is in
place to protect the battery compartment from moisture.
Note: An optional protective cover (PN 1081366) is available to help protect the touch-
screen. Follow the installation instructions shipped with the cover.
Important: Do not immerse the unit in water. Dampen a soft cloth with mild detergent
to wipe the exterior of the unit clean.
