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.

8. Do not store the LCD module below the temperature conditions described in the

specifications. Failure to do so could result in freezing of the liquid crystal due to cold

air or loss of resilience or other damage.

9. Do not disassemble the LCD module. Such actions could result in improper operation.
