doc . no vms350gf01 rev.no 000 page 35 /35 14-3. storage do not leave the module in high temperature and humidity for a long time. it is recommended to store the module in the place with temperature from 0to35 and relative humidity of less than 70%. do not store the lcd module in the direct sunlight. store the module in a dark place without sunlight and fluorescent. avoid intensive shock and falls from a height.
