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 LCD panel to malfunction.
Storage temperature: –20°C to +60°C (–4°F to +140°F).
• Is the AC cord disconnected? (See page 3.)
• Has the power been turned on? (See page 7.)
• Make sure the a (Power) switch of the TV is set to ON.
• External influences such as lightning, static electricity, etc., may cause improper
operation. In this case, operate the unit after first turning the power off, or
unplugging the AC cord and re-plugging it in after 1 or 2 minutes.
• Are batteries inserted with polarity (e, f) aligned? (See page 4.)
• Are batteries worn out? (Replace with new batteries.)
• Are you using it under strong or fluorescent lighting?
• Is a fluorescent light illuminated to remote control sensor?
• Adjust the picture levels. (See page 9.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the system setting. (See page 19.)

• Is the correct input selected? (See page 21.)
• Is a non-compatible signal being input? (See page 24.)
• Is picture adjustment correct? (See pages 9 and 10.)
• Is the antenna connected properly? (See page 3.)
