13 handling precautions (1) a lcd m odule is a fragile item and should not be subjected to strong m echanical shocks. (2) a void applying pressure to the m odule surface. this will distort the glass and cause a change in color . (3) under no circum stances should the position of the bezel tabs or their shape be m odified. (4) do not m odify the display pcb in either shape or positioning of com ponents. (5) do not m odify or m ove location of the zebra or heat seal connectors. (6) the device should only be soldered to duri ng interfacing. modification to other areas of the board should not be carried out. (7) in the event of lcd breakage and resultant l eakage of fluid do not inhale, ingest or m a ke contact with the skin. if contact is m a de rinse im m e diately . (8) w h en cleaning the m odule use a soft dam p cloth with a m ild solvent, such as isopropyl or ethyl alcohol. the use of water , ketone or arom atic is not perm itted. (9) prior to initial power up input signals should not be applied. (10) protect the m odule against static electricity and observe appropriate anti-static precautions. date : 2001/12/12 ampire co., l t d. 15
