In case of mass production, every order shall draw 10pcs. of samples to conduct a reliability test in according to the following condition: Item Condition Time (hrs) High temp. storage +60 C 48 Low temp. storage -20 C 48 Humidity 40 C / 90%RH Recovery time should be 24 hours minimum Cautions for use Pay attention to following points of handling the COG LCD module: 1. Take utmost care when handling as these products are made of glass. Any strong mechanical impact due to falling, etc. may cause damage(breakage or cracking). 2. Polarizer is made of soft material and is easily damaged, take utmost care when handling. The protective film attached is to prevent scratch and protect against dirt, it is recommended that this film should be kept sealing before use. 16

20 3. Clean polarize with a soft cloth. TRI-T COMPAN LIMITED 4. Do not touch the connection terminals of the display with bare hand, it will cause disconnection or defective insulation of terminals 5. Avoid use or extended storage at high temperature and high humidity. For extended storage, select a storage area where the temperature is 20±8 and the relative humidity is less than 65% 6. Do not expose the display to the direct sunlight or UV light. 7. Be careful not to touch or swallow liquid crystal that might leak from a damaged cell. Any liquid crystal adheres to skin or clothes, wash it off immediately with soap and water. Limited Warranty TRI-T modules are not consumer products, but may be incorporated by TRI-T s customers into consumer products or components thereof, TRI-T does not warrant that its modules and components are fit for any such particular purpose. 1. The liability of TRI-T is limited to repair or replacement on the terms set forth below. TRI-T will not be responsible for any subsequent or consequential events or injury or damage to any personnel or user including third party personnel and/or user. Unless otherwise agreed in writing between TRI-T and the customer, TRI-T will only replace or repair any of its LCD which is found defective electrically or visually when inspected in accordance with TRI-T QUALIT INSPECTION STANDARD. 2. No warranty can be granted if any of the precautions state in handling liquid crystal display above has been disregarded. Broken glass, scratches on polarizer mechanical damages as well as defects that are caused accelerated environment tests are excluded from warranty. 3. In returning the module, they must be properly packaged; there should be detailed description of the failures or defect. 17
