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 Set 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) Connectors 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.
