CV12032A HANDLING PRECAUTIONS (1) CAUTION OF LCD HANDLING & CLEANING Use soft cloth with solvent (recommended below) to clean the display surface and wipe lightly. - Isopropyl alcohol, ethyl alcohol, trichlorotriflorothane Do not wipe the display surface with dry or hard materials that will damage the polarizer surface. Do not use the following solvent; -water, ketone, aromatics (2) CAUTION AGAINST STATIC CHARGE The LCD modules use CMOS LSI drivers, so customers are recommend that any unused input terminal would be connected to VDD or VSS , do not input any signals before power is turned on, and ground your body, work/assembly areas, assembly equipment to protect against static electricity. (3) PACKAGING Avoid intense shock and falls from a height and do not operate or store them exposed direct to sunshine or high temperature/humidity. (4) CAUTION FOR OPERATION It is an indispensable condition to drive LCD's within the specified voltage limit since the higher voltage than the limit causes the shorter LCD life. The use of direct current drive should be avoided because an electrochemical reaction due to direct current causes LCD's undesirable deterioration. Response time will be extremely delayed at low temperature, and LCD's show dark color at high temperature. However those phenomena do not mean malfunction or out of order with LCD's. Some font will be abnormally displayed when the display area is pushed hard during operation. But it resumes normal condition after turning off once. (5) SAFETY For crash damaged or unnecessary LCD's, it is recommended to wash off liquid crystal by either of solvents such as acetone and ethanol and should be burned up later. When any liquid leaked out of a damaged glass cell comes in contact with your hands, wash it off with soap and water. WARRANTY CLOVER will replace or repair any of her LCD module in accordance with her LCD specification for a period of one year from date of shipment. The warranty liability of Clover is limited to repair and/or replacement. Clover will not be responsible for any subsequent or consequential event. .05 8 8
