1. Handling Precautions

z If any signals or power lines deviate from the power on/off sequence, it may cause shorten the life of the LCD module.

z The LCD panel and the CFL are made of glass and may break or crack if dropped on a hard surface, so please handle

them with care.

z CMOS ICs are included in the LCD panel. They should be handled with care, to prevent electrostatic discharge.

z Do not press the reflector sheet at the LCD module to any directions.

z Do not stick the adhesive tape on the reflector sheet at the back of the LCD module.

z Please handle with care when mount in the system cover. Mechanical damage for lamp cable/lamp connector may

cause safety problems.

z Small amount of materials having no flammability grade is used in the LCD module. The LCD module should be supplied

by power complied with requirements of Limited Power Source (2.11, IEC60950 or UL60950), or be applied exemption

conditions of flammability requirements (4.4.3.3, IEC60950 or UL60950) in an end product.

z The LCD module is designed so that the CFL in it is supplied by Limited Current Circuit (2.4, IEC60950 or UL60950).

z The fluorescent lamp in the liquid crystal display (LCD) contains mercury. Do not put it in trash that is disposed of in

landfills. Dispose of it as required by local ordinances or regulations.

z Never apply detergent or other liquid directly to the screen.

z Wipe off water drop immediately. Long contact with water may cause discoloration or spots.

z When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth; do not use solvents or abrasives.

z Do not touch the front screen surface in your system, even bezel.

z Gently wipe the covers and the screen with a soft cloth.

z The information contained herein is presented only as a guide for the applications of our products. No

responsibility is assumed by CHI MEI Optoelectronics for any infringements of patents or other right of the

third partied which may result from its use. No license is granted by implication or otherwise under any patent
