• To enjoy HD images from external equipment, you are required to set up HDMI

connection or component connection.

• If the program content is not of HD quality, HD images cannot be displayed. Check

that the program you are viewing provides HD images.

• The HD cable/satellite set-top box may need to be confi gured to output HD images

via cable/satellite.

• The cable/satellite broadcast may not support a signal resolution of 1080p.

performance.

Appendix

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 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.
