Cautions
regarding
use in high and low temperature
environments
• When the unit is used in a low temperature
space (e.g. room, office), the picture may leave trails or appear
slightly
delayed.
This is not a malfunction,
and the unit will recover when the temperature
returns to normal.
• Do not leave the unit in a hot or cold location.
Also, do nol leave the unit in a location
exposed
to direct sunlight or near a
heater, as this may cause the cabinet to deform
and the Liquid Crystal
panel to malfunction.
Storage temperature:
-4°F to +140°F
