## 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   If the LCD panel breaks , be careful not to get the liquid crystal to touch your skin. 

- 5.1.2   If the liquid crystal touches your skin or clothes , please wash it off immediately by using soap and water. 

## **5.2 HANDLING** 

- 5.2.1   Avoid any strong mechanical shock which can break the glass. 

- 5.2.2   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. 

   - 5.2.3   Do not remove the panel or frame from the module. 

- 5.2.4   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.) 

   - 5.2.5   Do not wipe the polarizing plate with a dry cloth , as it may easily scratch the surface of plate. 

- 5.2.6   Do not touch the display area with bare hands , this will stain the display area. 

- 5.2.7   Do not use ketonics solvent & aromatic solvent. Use with a soft cloth soaked with a cleaning naphtha solvent. 

      - 5.2.8   To control temperature and time of soldering is 280 ± 10 ℃ and 3-5 sec. 

- 5.2.9   To avoid liquid (include organic solvent) stained on LCM . 

## **5.3 STORAGE** 

   - 5.3.1   Store the panel or module in a dark place where the temperature is 25 ℃ ± 5 ℃ and the humidity is below 65% RH. 

   - 5.3.2   Do not place the module near organics solvents or corrosive gases. 

- 5.3.3   Do not crush , shake , or jolt the module. 

## **5.4 TERMS OF WARRANTY** 

- 5.4.1   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 electronicequipment , 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.
