4. General Maintenance

4.1 Caring For The Touchscreen

The touchscreen 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.
Protect the touchscreen from the following chemicals:
• mustard,
• sodium hydroxide,
• concentrated caustic solutions,
• benzyl alcohol, and
• concentrated miner acids.
If touchscreens are used in harsh environments, apply disposable
screen protectors to dramatically extend the life of the touchscreen.

4.2 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 unit.
• Avoid abrasive cleaners, solvents or strong chemicals. 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 and touchscreen, use iso-
propyl alcohol.
