FST Series Product Specifications
5. Handling Notes
5-1. Precautions
§ This product is intended for use in standard applications (computers, office automation, and other office
equipment, industrial, communications, and measurement equipment, personal and household devices,
etc.) Please avoid using this product for special applications where failure or abnormal operation may
directly affect human lives, or cause physical injury or property damage, or where extremely high levels
of reliability are required (such as aerospace systems, vehicle operating control, atomic energy controls,
medical devices for life support, etc.).
5-2. Handling Notes
§ Do not depress or scratch the product with any object with a sharp edge or end.
§ Do not forcibly bend or fold the product.
§ When the product is stored, make sure it is packed in a packing box and stored in a storage temperature
range, eliminating any outside load.
§ Do not use or store the product under a condition where the product will be exposed to water, organic
solution or acid.
§ Do not use the product under the direct sunlight.
§ Do not disassemble the product.
§ When you handle the product, Hold the product by its body. Do not hold by the tail.
§ Clean the product with a soft cloth or a soft cloth with neutral detergent or alcohol. When contaminated
by chemicals, wipe them off immediately with caution not to cause injury to human body.
§ The edge of the glass is not rounded and may cause injury.
5-3. Construction Notes
§ The environmental specifications, mechanical characteristics, and electrical characteristics are only
applied to the Active Area.
§ Do not use the touchscreen when the condensation occurs. The condensation inside of the touchscreen
is a natural phenomenon and should disappear after the touchscreen is warmed up.
5-4. Electrical & Software Notice
The best performance can be obtained when used with the original 5 wire analog resistive touchscreen
controller, “TSC-20” Series. If the touchscreen controller or controller software is to be developed by the
customer, please note the following:
§ There is a contact resistance between the top and bottom electrodes and it changes by the pressure of a
finger or a pen. The data must be read after the contact resistance becomes stabilized.
§ The terminal resistance of the 5 wire analog resistive touchscreen varies by the individual, time, and
environment. The controller software must have the calibration function to adjust the input position and
the display position.
§ The 5 wire analog resistive touchscreen outputs 2 point input as 1 point in between the 2 points. The
controller software must not be designed to have the 2 point input function.
§ For drawing applications, the line may be intermittent when the pen comes on the dot spacers. A
software compensation is needed.
