• To view the TV comfortably, the recommended viewing 

position is from four to seven times the screen’s vertical 
length away from the TV set.

• To obtain a clear picture, do not expose the screen to direct 

illumination or direct sunlight. If possible, use spot 
lighting directed down from the ceiling.

• View the TV in moderate light, as viewing the TV in poor 

light or during long period of time, strains your eyes.

• Adjust the volume so as not to trouble your neighbours. 

Sound carries very easily at night time. Therefore, closing 
the windows or using headphones is suggested.

• When using headphones, adjust the volume so as to avoid 

excessive levels, as hearing damage may result.

• Although the LCD screen is made with high-precision 

technology and 99.99% or more of the pixels are effective, 
black dots may appear or bright points of light (red, blue, 
or green) may appear constantly on the LCD screen. This 
is a structural property of the LCD screen and is not a 
malfunction.

• Do not push or scratch the front filter, or place objects on 

top of this TV set. The image may be uneven or the LCD 
screen may be damaged.

• If this TV set is used in a cold place, a smear may occur in 

the picture or the picture may become dark. This does not 
indicate a failure. These phenomena disappear as the 
temperature rises.

• Ghosting may occur when still pictures are displayed 

continuously. It may disappear after a few moments.

• The screen and cabinet get warm when this TV set is in 

use. This is not a malfunction.

• The LCD screen contains a small amount of liquid crystal 

and mercury. The fluorescent tube used in this TV set also 
contains mercury. Follow your local ordinances and 
regulations for disposal.

Be sure to unplug the mains lead connected to the TV set 
from mains socket before cleaning.
To avoid material degradation or screen coating degradation, 
observe the following precautions.
• Do not push on the screen, scratch it with a hard object, or 

throw anything at it. The screen may be damaged.

• Do not touch the display panel after operating the TV set 

continuously for a long period as the display panel 
becomes hot.

• We recommend that the screen surface be touched as little 

as possible.

• To remove dust from the screen surface/cabinet, wipe 

gently with a soft cloth. If dust is persistent, wipe with a 
soft cloth slightly moistened with a diluted mild detergent 
solution.

• Never use any type of abrasive pad, alkaline/acid cleaner, 

scouring powder, or volatile solvent, such as alcohol, 
benzene, thinner or insecticide. Using such materials or 
maintaining prolonged contact with rubber or vinyl 
materials may result in damage to the screen surface and 
cabinet material.

• The ventilation holes can accumulate dust over time. To 

ensure proper ventilation, we recommend removing the 
dust periodically (once a month) using a vacuum cleaner.

• If the angle of the TV set is to be adjusted, steady the base 

of the stand with your hand to prevent the TV set from 
becoming separated from the stand. Be careful not to get 
your fingers caught between the TV set and the stand.

• Do not install optional components too close to the TV set. 

Keep optional components at least 30 cm away from the 
TV set. If a VCR is installed in front of the TV set or 
beside the TV set, the picture may become distorted.

• Picture distortion and/or noisy sound may occur if the TV 

set is positioned in close proximity to any equipment 
emitting electromagnetic radiation.
