The touch
panel does
not respond
to touch.
Are strong light sources
or devices that use
infrared rays located
nearby?
The touch panel is an optical device that uses
infrared rays. Incident light that contains large
quantities of infrared rays can prevent proper
functioning. Move light sources as far away from the
touch panel as possible.
Fluorescent light:
Does not produce infrared light, so it does
not cause problems.
Sunlight:
Locate the touch panel where it is not
exposed to direct sunlight.
White candescent light:
Contains the most infrared light and can
readily affect the touch panel. Move light
sources as far away from the touch panel as
possible.
