## **Precautions in use of LCD Modules** 

(1)Avoid applying excessive shocks to the module or making any alterations or modifications to it. 

- (2)Don’t make extra holes on the printed circuit board, modify its shape or change the components of LCD module. 

- (3)Don’t disassemble the LCM. 

- (4)Don’t operate it above the absolute maximum rating. 

- (5)Don’t drop, bend or twist LCM. 

- (6)Soldering: only to the I/O terminals. 

- (7)Storage: please storage in anti-static electricity container and clean environment. 

(8) Midas have the right to change the passive components, including R3,R6 & backlight adjust resistors. (Resistors, capacitors and other passive components will have different appearance and color caused by the different supplier.) 

(9) Midas have the right to change the PCB Rev. (In order to satisfy the supplying stability, management optimization and the best product performance...etc, under the premise of not affecting the electrical characteristics and external dimensions, Midas have the right to modify the version.) 

- (10) To ensure the stability of the display screen, please apply screen saver after showing 30 mins of fixed display content. 

- (11)Please heat up a little the tape sticking on the components when removing it; otherwise the components might be damaged.
