1.3 ATTENTIONS 

 

(1) Do not press or rub on the sensitive display surface. If customers clean on the panel surface, NEC 

recommends using the cloth with ethanolic liquid such as screen cleaner for LCD. 

(2) When handling the LCD module, 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) Do not touch with bare hand or dirt the cold cathode fluorescent lamp in the lamp holder. If do so, 

display mura might occur. 

(4) Do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the 

damage for high voltage side of the lamp. 

 
 
 
 
 
 
 
(5) Properly connect the adaptable plug (backlight side) to socket (inverter side) 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 
of high voltage circuit. 

(6) Do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage. 
(7) Do not shock and press the LCD panel and the backlight. There is a danger of breaking, because 

they are made of glass. 

(8) If dirt or dust gets on the cold cathode fluorescent lamp, display mura might occur. Therefore, NEC 

recommends using a clean room or clean bench (the class "D" level).
