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. 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.
If the touchscreen is used in harsh environments, consider applying a disposable
screen protector (WA6111-G2). 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.
3.11.2 Cleaning The WORKABOUT PRO
Important: Do not immerse the unit in water. Dampen a soft cloth with mild
detergent to wipe the unit clean.
• Use only mild detergent or soapy water to clean the hand-held unit.
• Avoid abrasive cleaners, solvents or strong chemicals for cleaning. The
plastic case is susceptible to harsh chemicals. The plastic is partially soluble
in oils, mineral spirits and gasoline. The plastic slowly decomposes in
strong alkaline solutions.
• To clean ink marks from the keypad or touchscreen, use isopropyl alcohol.
