In a situation that a detection function for the backlight burnout has been ineffective, if a burnout of the backlight

happened, unlike in an extinction condition of the backlight of FP, the touch panel is still active. If an operator fails

to notice that the backlight is burned out and touches the panel, a potentially dangerous machine miss-operation can

occur. Therefore, do not set up switches on the touch panel of an FP that are likely to cause human error or physical

damage triggered by mis-operation.

If your FP’s backlight suddenly turns OFF, use the following steps to determine if the backlight is actually burned

out.

1) If your current FP application or Auto off Disp function is not set, and the screen has gone blank, your backlight is

burned out.

2) If your current FP application or Auto off Disp function is set, and if touching the screen does not cause the dis-

play to reappear, your backlight has been burned out.

If substantial amounts of metallic dust, water or liquids enter the FP unit, turn off the power supply immediately,

unplug the power cord, and contact your local FP distributor.

When installing the FP unit, be sure to follow the instructions given in “Chapter 3 Installation and Wiring,” to insure

it is done correctly.

Do not use the FP in an environment with flammable gas, since it may cause an explosion.

The FP is not appropriate for use with aircraft control devices, aerospace equipment, central trunk data transmission

(communication) devices, nuclear power control devices, or medical life support equipment, due to these devices’

inherent requirements of extremely high levels of safety and reliability.

When using the FP with transportation vehicles (trains, cars and ships), disaster and crime prevention devices, vari-

ous types of safety equipment, non-life support related medical devices, etc, redundant and/or failsafe system

designs should be used to ensure the proper degree of reliability and safety.

Do not press the screen’s touch surface too strongly with either your finger or a hard object, since the touch surface

may be damaged.

When the surface of the display screen becomes dirty or smudged, clean the display with a cloth soaked in a neutral

detergent. Do not use paint thinner or organic solvent.

Do not press on the touch panel's face with sharp objects, such as a mechanical pencil or screwdriver, since it might

damage the LCD panel.

Avoid using or storing the FP in direct sunlight, excessively dusty or dirty environments, or where chemicals or their

vapors are present in the air.
