2.Precautions in Use of LCD Module

(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.
