Cleaning the Touch Screen
To clean the touch screen, use a lint-free, soft cloth dampened with standard,
household glass cleaning solution as follows:
1. Spray a small amount of glass cleaner onto the cloth.
2. Wipe the glass of the touch screen to remove any dirt, dust, or finger
marks.
3. Wipe the clear surfaces around the edges of the screen.
4. Remove any residual glass cleaner with a dry, soft, lint-free cloth.
WARNING:
Do not spray the cleaner directly onto the touch screen as this could leave
residue on the optical surfaces.
Do not use an abrasive cleaner or rough cloth as this could damage the
optics.
