DMF6104NF-FW (AE) No.97-0106 OPTREX OPTREX CORPORATION Page 16/17 10.Handling Precautions Operex Products are designed for use in ordinary electronic devices such as business machines, telecommunications equipment, measurement devices and etc.. Optrex Products are not designed, intended, or authorized for use in any application in which the failure of the product could result in a situation where personal injury or death may occur. These applications include, but are not limited to, life-sustaining equipment, nuclear control devices, aerospace equipment, devices related to hazardous or flammable materials, etc. (If Buyer intends to purchase or use the Optrex Products for such unintended or unauthorized applications, Buyer must secure prior written consent to such use by a responsible officer of Optrex Corporation.) Should Buyer purchase or use Optrex Products for any such unintended or unauthorized application (without such consent), Buyer shall indemnify and hold Optrex and its officers, employees, subsidiaries, affiliates and distributors harmless against all claims, costs, damages and expenses, and reasonable attorney's fees, arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that Optrex was negligent regarding the design or manufacture of the part. 1) LCD may be broken because it is made of glass. 2) Polarizer is a soft material and can easily be scratched. 3) Please avoid static electricity. ① Please be sure to ground human body and electric appliances during work. ② It is preferable to use conductive mat on table and wear cotton clothes or conduction processed fiber. Synthetic fiber is not recommended. ③ Please slowly peel off protective film, because static electricity may be charged. 4) If it is necessary to store LCD modules for a long time, please comply with the following procedures. If storage condition is not satisfactory, display (especially polarizer) may be deteriorated or soldering I/O terminals may become difficult (some oxide is generated at I/O terminals plating). ① Store as delivered by Optrex ② If you store as unpacked, put in anti-static bag, seal its opening and store where it is not subjected to direct sunshine nor fluorescent lamp. ③ Store at temperature 0 to +35℃ and at low humidity. Please refer to our specification sheets for storage temperature range and humidity condition. 5) The module does not contain excess current limiter. Please design the limiter to cut excess current in your power supply circuit. 6) Liquid crystal may be leaked when display is broken. Never taste it. If your hands or clothes touch it, please immediately wash using soap. 7) The connection between the bezel and VSS (GND) is not specified in the module. (Some module do not maintain connection between them.) Please consult OPTREX to specify the connection. 8) A high voltage over 1000V is applied at the connector of CFL cable when the CFL inverter is connected and energized. Please do not touch there incidentally or accidentally to avoid a skin burn. And please set the cable properly in the housing to avoid a worn-out of isolated cover of cable wire. Optrex shall not be responsible for any infringement of industrial property rights of third parties in any country arising out of the application or use of Optrex Products, except which directly concern the structure or production of such products.
