date : 2006/9/7 ampire co., ltd. 16 13 handling precautions (1) a lcd module is a fragile item and should not be subjected to strong mechanical shocks. (2) avoid applying pressure to the module surfa ce. this will distort the glass and cause a change in color. (3) under no circumstances should the position of th e bezel tabs or their shape be modified. (4) do not modify the display pcb in either shape or positioning of components. (5) do not modify or move location of the zebra or heat seal connectors. (6) the device should only be soldered to during interfacing. modification to other areas of the board should not be carried out. (7) in the event of lcd breakage and resultant leak age of fluid do not inhale, ingest or make contact with the skin. if contact is made rinse immediately. (8) when cleaning the module use a soft damp cloth with a mild solvent, such as isopropyl or ethyl alcohol. the use of water, ke tone or aromatic is not permitted. (9) prior to initial power up input signals should not be applied. (10) protect the module against st atic electricity and observ e appropriate anti-static precautions.
