1. Handling
                        (a) When the module is assembled, It should be attached to the system firmly
                           using every mounting holes. Be careful not to twist and bend the modules.
                        (b) Refrain from strong mechanical shock and / or any force to the module. In addition to
                            damage, this may cause improper operation or damage to the module.
                        (c) Note that polarizers are very fragile and could be easily damaged. Do not press or scratch
                            the surface harder than a HB pencil lead.
                        (d) Wipe off water droplets or oil immediately. If you leave the droplets for a long time,
                            Staining and discoloration may occur.
(e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth.
                        (f) The desirable cleaners are water, IPA (Isoprophyl Alcohol) or Hexane.
                            Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl
                            chloride. It might permanent damage to the polarizer due to chemical reaction.
                        (g) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or
                             mouth . In case of contact with hands, legs or clothes, it must be washed away thoroughly
                             with soap.
(h) Protect the module from static , it may cause damage to the C-MOS Gate Array IC.
                        (i) Use fingerstalls with soft gloves in order to keep display clean during the incoming
                             inspection and assembly process.
(l) Do not adjust the variable resistor which is located on the back side.
                        (m) Protection film for polarizer on the module shall be slowly peeled off just before use so
                           that the electrostatic charge can be minimized.
(n) Pins of I/F connector shall not be touched directly with bare hands.

                       (a) Do not leave the module in high temperature, and high humidity for a long time.
                           It is highly recommended to store the module with temperature from 0 to 35 °C and
                           relative humidity of less than 70%.
                       (c) The module shall be stored in a dark place. It is prohibited to apply sunlight or fluorescent
                           light during the store.
3. OPERATION
                        (b) Power supply should always be turned on/off by following item 6.3
                            “ Power on/off sequence “.
                        (c) Module has high frequency circuits. Sufficient suppression to the electromagnetic
                            interference shall be done by system manufacturers. Grounding and shielding methods
                            may be important to minimize the interference.
                        (d) The standard limited warranty is only applicable when the module is used for general
                            notebook applications. If used for purposes other than as specified, SEC is not to be
                            held reliable for the defective operations. It is strongly recommended to contact SEC
                            to find out fitness for a particular purpose.
4. OTHERS
                       (c) Do not exceed the absolute maximum rating value. ( the supply voltage variation, input
                           voltage variation, variation in part contents and environmental temperature, so on)
                           Otherwise the module may be damaged.
                       (d) If the module displays the same pattern continuously for a long period of time,it can be
                           the situation when the image “sticks” to the screen.
                       (e) This module has its circuitry PCB’s on the rear side and should be handled carefully in
                           order not to be stressed.
