because VS may increase due to the leak current which may be caused by wiring of CFL cables.
(Reference value : (1,720) Vrms Min.)
*2 We recommend that you should set the discharging tube current at lower than typical value
so as to prevent the heat accumulation of CFL tube from deteriorating a performance of the LCD.
*3 End of life is defined as when the illuminance or quantity of light has decreased to 50％ of the
initial value. Illuminance of light will drastically decrease when LCD is operated at lower
temperature for long hours.
VS
*4 The driving frequency of the CFL may interfere with the horizontal synchronous signal ,leaving
interference stripes on the display. So please evaluate LCD panels beforehand.
To avoid interference stripes, we recommend to separate as far as possible the CFL frequency
from the horizontal synchronous signal and its high harmonic frequency.
* There may be cases where interface noise on LCD PCB, generated by high-voltage products such as
inverters, may leave stripes on the display. Please be careful when designing a mold to take
into consideration that the inverter shall be located as far as possible from PCB. Shield
protection may be effective.

11-1. Incoming inspection
Please inspect the LCD within one month after your receipt.
11-2. 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.

１２．Precautions for use
12-1. Installation of the LCD
1. A transparent protection sheet shall be added to protect the LCD and its polarizers.
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. Do not pull the CFL lead wires and do not bend the root of the wires.
Housing should be designed to protect CFL lead wires from external stress.
12-2. Static Electricity
1. Since CMOS ICs are mounted directly onto the LCD glass, protection from static electricity is
required. Operator should wear ground straps.
12-3. 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. 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.
12-4. Storage
1. The LCD shall be stored within normal temperature and humidity.
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.
12-5. Screen Surface
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. A transparent protection sheet is attached to the polarizer. Please remove the protection
film slowly before use, paying attention to static electricity.
9. 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.
