20 5. NOTES Safety SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE If the LCD panel breaks, be careful not to get the liquid crystal in your Handling mouth. If the liquid crystal touches your skin or clothes, wash it off immediately using soap and plenty of water. Avoid static electricity as this can damage the CMOS LSI. The LCD panel is plate glass; do not hit or crush it. Do not remove the panel or frame from the module. The polarizing plate of the display is very fragile; handle it very carefully Mounting and Design Mount the module by using the specified mounting part and holes. To protect the module from external pressure, leave a small gap by placing transparent plates (e.g. acrylic or glass ) on the display surface, frame, and polarizing plate Design the system so that no input signal is given unless the power-supply voltage is applied. Keep the module dry. Avoid condensation, otherwise the transparent Storage electrodes may break. Store the module in a dark place where the temperature is 25 o C±10 o C and the humidity below 65% RH. Do not store the module near organic solvents or corrosive gases. Do not crush, shake, or jolt the module (including accessories). Cleaning Do not wipe the polarizing plate with a dry cloth, as it may scratch the surface. Wipe the module gently with soft cloth soaked with a petroleum benzine. Do not use ketonic solvents (ketone and acetoe) or aromatic solvents (toluene and xylene), as they may damage the polarizing plate. 6. OPERATION PRECAUTIONS Any changes that need to be made in this specification or any problems arising from it will be dealt with quickly by discussion between both companies.
