3.8 General Maintenance
3.8.1 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 con-
ductive coating. The chemicals listed below must not come into contact with the touchscreen:
• mustard
• ketchup
• sodium hydroxide
• concentrated caustic solutions
• benzyl alcohol
• concentrated acids
If the touchscreen is used in harsh environments, consider applying a disposable screen protector
(VA6200). 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.
Do not to expose the touchscreen to direct sunlight for prolonged periods of time. If this is unavoidable, use
a UV screen protector to extend the life of the screen.
3.8.2 Cleaning the VH10
• Use only mild detergent or soapy water to clean the vehicle-mount.
• Avoid abrasive cleaners, solvents or strong chemicals for cleaning. The VH10 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.
• Exposure to aircraft de-icing fluids can degrade the plastics on VH10. If the VH10 is used near aircraft
de-icing environments, regular rinsing with water is recommended.
• To clean ink marks from the keyboard and touchscreen, use isopropyl alcohol.
Note: The VH10 will be reset if you choose to switch shells.
Important: Do not immerse the unit in water. Dampen a soft cloth with mild detergent to wipe
the unit clean.
To prevent damage to the touchscreen, use only your finger or the stylus (pen)
supplied with your VH10.
