3.9 General Maintenance
3.9.1 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 pro-
tector (CH6110). 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.
3.9.2 Cleaning The Ikôn
•Use only mild detergent or soapy water to clean the Ikôn.
• 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 and touchscreen, use isopropyl alcohol.
Important: Do not immerse the unit in water. Dampen a soft cloth with mild detergent
to wipe the unit clean.
