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 hard end.

§ Do not put this product close to fire.

§ Do not wipe this product with too much load.

§ Do not strongly rub this product locally. It may affect the product’s functions.

§ Do not hit the product with a hard object.

§ 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 analog resistive touchscreen controller, “TSC-10” 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 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 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.

5-5. Mounting Notes

§ Bezel Edge Bezel edge must be positioned in the area between the Active

Area and the Viewing Area. The bezel may press the touchscreen and cause input if the edge enters the Active Area.

§ Gap between the Bezel and Touchscreen A gap of approximately 0.5mm is needed between the bezel

and the top electrode. It may cause unexpected input if the gap is too narrow.

§ Cushion If a cushion is used between the bezel and the top electrode,

the cushion must be free enough to absorb the expansion and contraction difference between the bezel and the top electrode. If the cushion is squashed too hard, the expansion and the contraction difference may cause the distortion to the top electrode. The cushion must be positioned more than 1mm outward from an inside of the insulation area. (Please refer to right figure)

§ Tolerance There is a tolerance of 0.2 to 0.3mm for the dimensions of the

touchscreen and the tail. A gap must be made to absorb the tolerance in the case and the connector.

§ Tail The tail must not be forcibly stressed or bent too hard to avoid

the conduction in the insulated area and wire breaking.

§ Mounting Touchscreen must be held from the bottom such as the

structure gluing the touchscreen onto the display. If the touchscreen is glued to the bezel, the adhesion between the top and bottom electrode is stressed and may come off.

§ Forbidden Area The area within 2mm from the insulation area is structurally

week for the pressure, espcially for pen use. The film may be forcibly bent and may cause defection. This area must be protected by the bezel and input must be avoided.

§ Air Vent Most of the touchscreens have the air vent to equalize the

inside air pressure to the outside one. The air vent must be open and liquid contact must be avoided as the liquid may be absorbed if the lquid is accumilated near the air vent. The top electlode must not be swelled by the air pressure from inside of the case.

6. Warranty

6-1. Warranty Period

§ The warranty period is limited to 1 year from the date of shipping. The warranty for the initial defection such as appearance defection is limited to 1 month.

§ Any defected parts under proper use will be examined by the supplier and replaced by the new parts if the defection is considered to be caused by the supplier.

§ The replacement is subject to be included in the next lot.

6-2. Warranty Target

§ The warranty only covers the product itself and does not cover any damage to others caused by using this product. Onsite repair or replacement is not supported.

§ We will do our best for delivery problem and product defections, but the warranty for the production line is not covered.

§ Resistive touchscreens are structurally not repairable. All defections are subject to replacement.

6-3. Warranty Exceptions

Following conditions are not covered with the warranty and subject to charge.

§ Any malfunctions and damages during transportation and transfer by the user.

§ Any malfunctions and damages caused by a natural disaster or a fire.

§ Any malfunctions and damages caused by static electricity

§ Any malfunctions and damages caused by the failure of the associated equipment.
