1.2 CAUTIONS
(1) Be sure to wait some time after turning power OFF before starting replacement work. There is a
danger of burn injury, because the lamp holders are hot after working.
(2) Take care not to injure yourself while treating the metal frame of the lamp holder.
(3) Do not shock and press the LCD panel and the lamp holder. There is a danger of breaking,
because they are made of glass.
1.3 ATTENTIONS
(1) Do not press or rub on the sensitive LCD panel surface
of the LCD module. When cleaning the
LCD panel surface, use of the cloth with ethanolic liquid such as screen cleaner for LCD is
recommended.
(2) When handling the product, take the measures of electrostatic discharge with such as earth band,
ionic shower and so on, because the LCD module may be damaged by electrostatic.
(3) Properly connect the lamp cable (FPC) to socket without incomplete connection. After
connecting, be careful not to hook the lamp cables because incomplete connection may occur by
hooking the lamp cables. This incomplete connection may cause abnormal operation.
(4) If dirt or dust gets on the luminous portion of LED in the lamp holder, display mura might occur.
Therefore, NEC recommends using a clean room or clean bench (the class "D" level).
