4. PRECAUTIONS

Safety￿

If the LCD panel is damaged, be careful not to get the liquid crystal in your mouth. If the liquid crystal touches your skin or clothes, promptly wash it off using soap and plenty of water.

Handling

Avoid static electricity, as it will damage the CMOS LSI.

The LCD panel is made of plate glass. Do not hit or crush it.

￿Do not remove the panel or frame from the module.

The polarizer of the display is very fragile. Handle it very carefully.

Mounting and design

￿Mount the module by using the specified mounting parts and holes.

To protect the module against external pressure, place a transparent plate (e.g., acrylic or glass) on the module, leaving a small gap between the display surface and transparent plate.

Example

Small gap

Exterior face

Module

Screw

￿Design the system so that no input signal is given unless the power-supply voltage is applied.

Keep the module dry. Avoid condensation to prevent the transparent electrodes from being damaged.

Storage

Store the module in a dark place, where the temperature is 25￿C ￿10￿C and the relative humidity below 65%.

￿Do not store the module near organic solvents or corrosive gases.

Keep the module (including accessories) safe from vibration, shock and external pressure.

Cleaning

Do not wipe the polarizer with a dry cloth, as it may scratch the surface.

￿Wipe the module gently with a soft cloth soaked with a petroleum benzine.

Do not use ketonic (ketone) solvents (ketone and acetone) or aromatic solvents (toluene and xylene), as they may damage the polarizer.
