SAFETY INSTRUCTION Handling the LCD Module Safety Precaution In the event that the screen is damaged or the liquid crystal (fluid) leaks, do not breathe in or drink this fluid. Also, never touch this fluid. Such actions could cause toxicity or skin irritation. If this fluid should enter the mouth, rinse the mouth thoroughly with water.

6. CMOS-LSI circuitry is used in the LCD module, so avoid damage due to static electricity. When handling the module, use a wrist ground or anchor ground. 7. Do not expose the LCD module to direct sunlight or strong ultraviolet rays for an extended period of time.
Page 12
9. Do not disassemble the LCD module. Such actions could result in improper operation. 10. When transporting the LCD module, do not use packing containing epoxy resin (amine) or silicon resin (alcohol or oxim). The gas generated by these materials can cause loss of polarity.
