Limitation of Application: Jing Handa 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) Jing Handa 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 .
晶汉达 · JHD MODEL: JHD1804 Don’t Press the Metallic Frame and Disassemble 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. Slowly Peel Off Protective Film! Avoid static electricity. LCD may be shifted or conductive rubber may be reshaped, which will cause defects. Avoid Static Electricity! Wear Gloves While Handing! Please be sure to ground human body and electric apploances during work.
晶汉达 · JHD MODEL: JHD1804 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.
