(shock: to be not greater 539m/s 2 and to be not greater 11ms, pressure: to be not greater 19.6n) 5.3 attentions 5.3.1 handling of the product take hold of both ends without touch the circuit board when customer pulls out products (lcd modules) from inner packing box. if customer touches it, products may be broken down or out of adjustment, because of stress to mounting parts. do not hook cables nor pull connection cables such as flexible cable and so on, for fear of damage. if customer puts down the product temporarily, the product puts on flat subsoil as a display side turns down. take the measures of electrostatic discharge such as earth band, ionic shower and so on, when customer deals with the product, because products may be damaged by electrostatic. the torque for mounting screws must never exceed 0.29n ? m. higher torque values might result in distortion of the bezel. do not press or rub on the sensitive display surface. if customer clean on the panel surface, nec corporation recommends using the cloth with ethanolic liquid such as screen cleaner for lcd. do not push-pull the interface connectors while the product is working, because wrong power sequence may break down the product. 5.3.2 environment do not operation in dewdrop atmosphere and corrosive gases. do not operate or store in high temperature or high humidity atmosphere. keep the product in antistatic pouch in room temperature, because of avoidance for dusts and sunlight, if customer stores the product. do not operate in high magnetic field. circuit boards may be broken down by it. use an original protection sheet on the product surface (polarizer). adhesive type protection sheet should be avoided, because it may change color or properties of the polarizer.
