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, mineral spirits and gasoline. The plastic slowly decomposes in strong alkaline solutions.
To clean ink marks from the keypad and touchscreen, use isopropyl alcohol.
