• Remote control unit does not
operate.
• Picture is cut off/with sidebar
screen.

misalignment

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.
Storage temperature: –4°F to +140°F (–20°C to +60°C)
