breakage of screen glass or damage to driving circuit. Therefore it must be packed in a strong case 
before the transportation or handling.

prevent the temperature and humidity from exceeding the limits as specified in the manual. For 
prolonged storage, it is necessary to house it in an anti-moisture bag and put them altogether in one 
place. The ambient conditions are tabulated as follows:

2.13 Display of a fixed picture for a long time may result in appearance of picture residue on the 
screen, as commonly called “ghost shadow”. The extent of the residual picture varies with the 
maker of LCD screen. This phenomenon doesn’t represent failure. This “ghost shadow” may remain 
in the picture for a period of time (several minutes). But when operating it please avoid displaying 
still picture in high brightness for a long time.
