10-3 Storage precautions

1) Avoid a high temperature and humidity area. Keep the temperature between

0°C and 35°C and also the humidity under 60%.

2) Choose the dark spaces where the product is not exposed to direct sunlight or

fluorescent light.

3) Store the products as they are put in the boxes provided from us or in the same

conditions as we recommend.

10-4 Operating precautions

1) Do not boost the applied drive voltage abnormally. Failure to do so may break

ICs. When applying power voltage, check the electrical features beforehand

and be careful. Always turn off the power to the LC module controller before

removing or inserting the LC module input connector. If the input connector is

removed or inserted while the power is turned on, the LC module internal circuit

may break.

2) The display response may be late if the operating temperature is under the

normal standard, and the display may be out of order if it is above the normal

standard. But this is not a failure; this will be restored if it is within the normal

standard.

3) The LCD contrast varies depending on the visual angle, ambient temperature,

power voltage etc. Obtain the optimum contrast by adjusting the LC dive

voltage.

4) When carrying out the test, do not take the module out of the low-temperature

space suddenly. Failure to do so will cause the module condensing, leading to

malfunctions.

5) Make certain that each signal noise level is within the standard (L level: 0.2Vdd

or less and H level: 0.8Vdd or more) even if the module has functioned properly.

If it is beyond the standard, the module may often malfunction. In addition,

always connect the module when making noise level measurements.

6) The CMOS ICs are incorporated in the module and the pull-up and pull-down

function is not adopted for the input so avoid putting the input signal open while

the power is ON.

7) The characteristic of the semiconductor element changes when it is exposed to

light emissions, therefore ICs on the LCD may malfunction if they receive light

emissions. To prevent these malfunctions, design and assemble ICs so that

they are shielded from light emissions.
