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
.
•
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.
