When the Receiver 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 Receiver will recover when the temperature returns to normal.
Do not leave the Receiver in a hot or cold location. Also, do not leave the Receiver in a location exposed to direct sunlight or near a
•
heater.
