Installation of the LCD 1) A transparent protection plate shall be added to protect the LCD and its polarizer 2) The LCD shall be installed so that there is no pressure on the LSI chips. 3) The LCD shall be installed flat, without twisting or bending. 4) Please design the housing window so that its edges are between the active area and the effective area of the LCD screen. 5) A transparent protection sheet is attached to the polarizer. Please remove the protection film slowly before use, paying attention to static electricity. 12-2. Static electricity 1) Since CMOS ICs are mounted directly onto the LCD glass, protection from static electricity is required. 2) Workers should use body grounding. Operator should wear ground straps. 12-3. LCD operation 1) The LCD shall be operated within the limits specified. Operation at values outside of these limits may shorten life, and/or harm display images. 12-4. Storage 1) The LCD shall be stored within the temperature and humidity limits specified. Store in a dark area, and protect the LCD from direct sunlight or fluorescent light. 2) Always store the LCD so that it is free from external pressure onto it. 12-5. Usage 1) DO NOT store in a high humidity environment for extended periods. Polarizer degradation bubbles, and/or peeling off of the polarizer may result. 2) The front polarizer is easily scratched or damage d. Prevent touching it with any hard material, and from being pushed or rubbed. 3) The LCD screen may be cleaned by wiping the scre en surface with a soft cloth or cotton pad using a little Ethanol. 4) Water may cause damage or discoloration of the polarizer. Clean condensation or moisture from any source immediately. 5) Always keep the LCD free from condensation during testing. Condensation may permanently spot or stain the polarizer. 6) Do not disassemble LCD because it will result in damage. 7) This Kyocera LCD has been specifically designed for use in general electronic devices, but not for use in a special environment such as usage in an active gas. Hence, when the LCD is supposed to be used in a special environment, evaluate the LCD thoroughly beforehand and do not expose the LCD to chemicals such as an active gas. 8) Please do not use solid-base image pattern for long hours because a temporary afterimage may appear. We recommend using screen saver etc. in cases where a solid-base image pattern must be used. 9) Liquid crystal may leak when the LCD is broken. Be careful not to let the fluid go into your eyes and mouth. In the case the fluid touches your body ; rinse it off right away with water and soap.
