Note: Be sure the ST7066U is not in the busy state (BF=0) before sending an instruction from the MPU to the ST7066. If an instruction is sent without checking the busy flag , the time between the first instruction and next instruction will take much longer than the instruction time itself. Refer to Instruction Table for the list of each instruction execution time .

5. PRECAUTION RELATING PRODUCT HANDLING
5.1 SAFETY
5.1.1 5.1.2 If the LCD panel breaks , be careful not to get the liquid crystal to touch your skin. If the liquid crystal touches your skin or clothes , please wash it off immediately by using soap and water. Avoid any strong mechanical shock which can break the glass. Avoid static electricity which can damage the CMOS LSI When working with the module , be sure to ground your body and any electrical equipment you may be using. Do not remove the panel or frame from the module. The polarizing plate of the display is very fragile. So , please handle it very carefully ,do not touch , push or rub the exposed polarizing with anything harder than an HB pencil lead (glass , tweezers , etc.) Do not wipe the polarizing plate with a dry cloth , as it may easily scratch the surface of plate. Do not touch the display area with bare hands , this will stain the display area. Do not use ketonics solvent & aromatic solvent. Use with a soft cloth soaked with a cleaning naphtha solvent. To control temperature and time of soldering is 280 10 and 3-5 sec. To avoid liquid (include organic solvent) stained on LCM . Store the panel or module in a dark place where the temperature is 25 and the humidity is below 65% RH. Do not place the module near organics solvents or corrosive gases. Do not crush , shake , or jolt the module. Applicable warrant period The period is within thirteen months since the date of shipping out under normal using and storage conditions. 5.4.2 Unaccepted responsibility This product has been manufactured to your company s specification as a part for use in your company s general electronic products. It is guaranteed to perform according to delivery specifications. For any other use apart from general electronic equipment , we cannot take responsibility if the product is used in nuclear power control equipment , aerospace equipment , fire and security systems or any other applications in which there is a direct risk to human life and where extremely high levels of reliability are required. 5
