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
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 Liquid Crystal panel to malfunction.
