3.11.1 Caring For The Touchscreen

The touchscreen is covered with 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:

•mustard, ketchup

•sodium hydroxide,

•concentrated caustic solutions,

•benzyl alcohol, and

•concentrated acids.

If the touchscreen is used in harsh environments, consider applying a disposable screen protector (PN HU6110). 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 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.
