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.
Storage temperature: f 4°F to e 140°F ( f 20°C to e 60°C)

Check if you pressed MONITOR POWER on the remote control unit.

(See page 16.) If the indicator on the LCD Monitor does not light up, press
POWER on the LCD Monitor.

Is the AC cord disconnected? (See page 8.)
•
Has the power been turned on? (See page 16.)
Has the main POWER been turned ON? (See page 8.)

•
External infl uences such as lightning, static electricity, may cause improper
operation. In this case, operate the unit after fi rst turning off the power of
the LCD Monitor or unplugging the AC cord and replugging it in after 1 or 2
minutes.
Is the FUNCTION set correctly? Set it to the LCD Monitor setting position.
•
Are batteries inserted with polarity ( e , f ) aligned? (See page 9.)
•
•
Are batteries worn out? (Replace with new batteries.)
•
Are you using it under strong or fl uorescent lighting?
•
Is a fl uorescent light illuminated near the remote control sensor?
•
Is the image position correct? (See page 26.)
•
Are screen mode adjustments such as picture size made correctly? (See
page 20.)
•
Adjust the picture tone. (See pages 23 and 24.)
•
Is the room too bright? The picture may look dark in a room that is too bright.
•
Check the input signal setting. (See page 26.)
•
Is the sleep timer set? (See page 17.)
•
Check the power control settings. (See page 25.)
•
The unit's internal temperature has increased. Remove any objects blocking
vent or clean.
•
Is connection to other components correct? (See pages 13 to 15.)
•
Is correct input signal source selected after connection? (See page 31.)
•
Is the correct input selected? (See page 31.)
•
Is picture adjustment correct? (See pages 23 and 24.)
•

•
Is a non-compatible signal being input? (See page 15.)
•
Is the volume too low? (See page 17.)

This is not a malfunction. This happens when the cabinet slightly expands and
contracts according to change in temperature. This does not affect the LCD
Monitor's performance.
