ELECTRICAL SPECIFICATIONS
Cautions regarding use in high and low temperature environments
•  When the unit is used in a low temperature space (e.g. room, offi ce), the 
picture may leave trails or appear slightly delayed. This is not a malfunc-
tion, and the unit will recover when the temperature returns to normal.
•  Do not leave the unit in a hot or cold location. Also, do not leave the 
unit in a location exposed to direct sunlight or near a heater, as this may 
cause the cabinet to deform and the LCD panel to malfunction. Storage 
temperature: –20°C to +60°C
.
Specifications
•  As a part of our policy of continuous im-
provement, SHARP reserves the right to 
make  design  and  specifi cation  changes 
for  product  improvement  without  prior 
notice. The performance specifi cation fi g-
ures indicated are nominal values of pro-
duction units. There may   be some devia-
tions from these values in individual units.
