Limitation of Application: Optrex products are designed for use in ordinary electronic devices such as business machines, telecommunications equipment,measurement devices and etc. Please handle the products with care. (see below) Optrex products are not designed,intended ,or authorized for use in any application 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. 2.Industrial Rights and Patents 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. No Press and Shock! Don’t Swallow or Touch Liquid Crystal! If pressure to LCD, orientation may be disturbed. LCD will broken by shock! Liquid Crystal may be leaked when display is broked. If it accidentally gets your hands, wash then with water! Don’t not Scratch! Polarizer is a soft material and can easily be scratched. No DC Voltage to LCD! DC volrage or driveing higher than the specified voltage will reduce the lifetime of the LCD. DC No! LCD MOUDULE SPECIFICATION FOR APPROVAL Waveshare LCD1602 DATE VER. PAGE 20/10/07 1.0 16 Don’t Press the Metallic Frame and Disassemble Slowly Peel Off Protective Film! the LCM Pressure on the metallic frame and PCB may deform the conductive rubber or break the liquid crystal cell and back light, which will cause defects. LCD may be shifted or conductive rubber may be reshaped, which will cause defects. Avoid static electricity. Avoid Static Electricity! Wear Gloves While Handing! Please be sure to ground human body and electric apploances during work. It is preferable to use conductive mat on table and wear cotton clothes or conduction processed fiber. Synthetic fiber is not recommended. It is preferable to wear gloves to avoid damaging the LCD. Please do not touch electrodes with bare hands or make them dirty. GLOVE Keep Away From Extreme Heat and Humidity! Use Alcohol to Clean Terminals! Alcohol LCD deteriorates. When attaching with the heat seal or anisontropically conductive film, wipe off with alcohol before use. LCD MOUDULE SPECIFICATION FOR APPROVAL Waveshare LCD1602 DATE VER. PAGE 20/10/07 1.0 17 Don’t Drop Water on LCD! Note that the presence of waterdrops or dew in the LCD panel may deteriorate the polarizer or corrade electrode. Precaution in Soldering LCD Module Basic instructions: Solder I/O terminals only. Use soldering iron without leakage. (1)Soldering condition to I/O terminals Temperature at tip of the iron: 280±10℃ Soldering time: 3~4 sec. Type of solder: Eutectic solder (containing colophony-flux) *Please do not use flux because it may soak into LCD Module or contaminate it. *It is preferable to peel off protective film on display surface after soldering I/O terminals is finished. (2)Remove connector or cable *When you remove connector or cable soldered to I/O terminals, please confirm that solder is fully melted. If you remove by force, electrodes at I/O terminals may be damaged(or stripped off). *It is recommended to use solder suction machine. Long-term Storage 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. Long-term Storage Please use power supply with built-in surge protection circuit. LCD MOUDULE SPECIFICATION FOR APPROVAL Waveshare LCD1602 DATE VER. PAGE 16.
