-1 3- 11. Supply Voltage Sequence Condition DO NOT apply DC voltage to the LCD panel. DC voltage induce irreversible electrochemical reactions and reduce LCD life. Always follow the power supply ON/OFF sequence of VDD first, input signal second, VCONT third and finally DISP. This will prevent DC driving of the LCD or CMOS LSI latch up as shown below. * Input signal : CP, LOAD, FRM，D0～D3 * The above sequence should be designed as to keep each normal figure on condition that liquid crystal module is loaded on your system. * Control the input signal and VCONT to the above ON-OFF timing when you switch ON/OFF the display during VDD and DISP are on. And design the circuit as VCONT's OFF level become GND level at the same time. * Control the supply voltage sequence not to float all signal line when the LCD panel is driving.

-1 5- １４．Warranty 14-1. Incoming inspection Please inspect the LCD within one month after your receipt. 14-2. Production Warranty Kyocera warrants its LCDs for a period of 12 months after receipt by the purchaser, and within the limits specified. Kyocera shall, by mutual agreement, replace or rework defective LCDs that are shown to be Kyocera's responsibility. 15．Precautions for use 15-1. Installation of the LCD 1. Please ground of an LCD module, in order to stabilize brightness and display quality. 2. The LCD shall be installed so that there is no pressure on the LSI chips. 3. The LCD shall be installed flat, without twisting or bending. 4. The display window size should be the same as the effective viewing area. 5. In case you use outside frame of effective viewing area as outward appearance of your product, unevenness of its outward appearance is out of guarantee. 6. This Kyocera LCD module has been specifically designed for use in general electronic devices, but not for use in a special environment such as usage in an active gas. Hence, when the LCD is supposed to be used in a special environment, evaluate the LCD thoroughly beforehand and do not expose the LCD to chemicals such as an active gas. 15-2. Static Electricity 1. Since CMOS ICs are mounted directly onto the LCD glass, protection from static electricity is required. Operation should wear ground straps. 15-3. LCD Operation 1. The LCD shall be operated within the limits specified. Operation at values outside of these limits may shorten life, and/or harm display images. 2. Adjust "LCD driving voltage" to obtain optimum viewing angle and contrast. 3. Operation of the LCD at temperature below the limit specified may cause image degradation and/or bubbles. It may also change the characteristics of the liquid crystal. This phenomenon may not recover. The LCD shall be operated within the temperature limits specified. 15-4. Storage 1. The LCD shall be stored within the temperature and humidity limits specified. Store in a dark area, and protected the LCD from direct sunlight or fluorescent light. 2. Always store the LCD so that it is free from external pressure onto it.
-1 6- 15-5. Caution items when handling the LCD 1. DO NOT store in a high humidity environment for extended periods. Image degradation, bubbles, and/or peeling off of polarizer may result. 2. The front polarizer is easily scratched or damaged. Prevent touching it with any hard material, and from being pushed or rubbed. 3. The LCD screen may be cleaned with a soft cloth or cotton pad. Methanol, or Isopropyl Alcohol may be used, but insure that all solvent residue is removed. 4. Water may cause damage or discoloration of the polarizer. Clean any condensation or moisture from any source immediately. 5. Always keep the LCD free from condensation during testing. Condensation may permanently spot or stain the polarizers. 6. Do not disassemble LCD module because it will result in damage. 7．Please do not use solid-base image pattern for long hours because a temporary afterimage may appear. We recommend to use screen saver etc. in cases where a solid-base image pattern must be used. 8．Liquid crystal may leak when the module is broken. Be careful not to let the fluid go into your eyes and mouth. In the case the fluid touches your body, rinse itoff right away with water and soap. 16．Reliability Data / Environmental Test TEST TEST TEST RESULT ITEM CONDITION TIME High Temp. 60 ℃ 240 h.
