1. Safety Precautions
(1) When moving or laying down a LCD Set, please deal with care. Avoid any impact
towards the LCD Set.
(2) Do not leave a broken LCD Set on for a long time. To prevent any further damages,
after check the broken Set’s condition, make sure to turn the power(AC) off.
(3) When opening the BACK COVER, you must turn off power(AC) to prevent any
electric shock.
(4) When loosening screws, check the connecting position and type of the screw. Sort
out the screws and store them separately because screws holding PCBs are
working as electric circuit grounding. Make sure to check if any screw is missing
when assembling.
(5) A LCD Sets contains different kinds of connector cables. When connecting or
disconnecting connector cables, check the direction and position of the cable
beforehand.
(6) When disconnecting connectors unplug the connectors slowly with care.
(7) Connecotrs are designed so that if the number of pins or the direction does not
match, connectors will not fit. When having problem in plugging the connectors,
make sure to check their kind, position and direction.
