5. General Maintenance
5.1 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, ketchup
• sodium hydroxide,
• concentrated caustic solutions,
• benzyl alcohol, and
• concentrated acids.
If touchscreens are used in harsh environments, apply disposable
screen protectors to dramatically extend the life of the touchscreen.
5.2 Cleaning The 7530 G2
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 7530 G2 has a plastic case that is susceptible to
harsh chemicals. The plastic is partially soluble in oils, min-
eral spirits and gasoline. The plastic slowly decomposes in
strong alkaline solutions.
To clean ink marks from the keypad and touchscreen, use
isopropyl alcohol.
