points or short out parts that could result in a fire
or an electric shock. Do not place any objects on 
the TV.

expose this appliance to rain or moisture. Do 
not place objects filled with liquids, such as 
vases, on the TV. 
¸ Do not use power-line operated V sets near 
water, such as in places like a bathtub, 
washbowl, kitchen sink, laundry tub, a wet 
basement, or near a swimming pool, etc. It may 
cause fire or electric shock. 
¸ Do not let this TV get wet. Never 
spill liquid of any kind on the TV. If 
water penetrates into the product, 
unplug the power cord and contact 
ViewSonic. Donot operate the TV. It 
may result in electric shock or 
damage to the TV. 
¸ To prevent fire, keep flammable 
objects or open flame (e.g. candles) 
away from the TV. 
INSTALLATION
To  do Wall mount installation, you  need  a Wall-
Mount  Bracket. When installing  or removing 
the  TV using the Wall-Mount   Bracket,  be  sure 
to use qualified contractors. If not properly 
secured  during installation or removal from the 
Wall-Mount Bracket, the TV may fall and cause 
serious injury. 
Optional wall mount
¸ When installing the TV using a Wall-Mount 
Bracket, make sure you follow the operating 
instructions supplied with the Wall-Mount 
Bracket. 
¸ Attach the brackets supplied with the Wall-
Mount Bracket. 
¸ The TV is not designed for hanging from 
the ceiling. It may fall and cause serious 
injury.
Placement
The TV should be installed near an easily 
accessible AC power outlet. 
Observe the following to prevent the TV from 
falling from the stand or wall mount.
¸Place the TV on a stable, level 
surface. ¸Do not hang anything on the TV. Do 
not allow 
children to climb on the TV. 
Do not install  the TV in places  subject to  extreme 
temperature, such as in direct sunlight, near a 
radiator,  or  heating vent. If the TV is exposed to 
extreme temperature, the TV may overheat and 
cause deformation of the enclosure or cause 
malfunction. Do not install the TV in a place 
exposed to direct air conditioning. If the TV is 
installed in such a location, mois t ur e may 
condense inside and may cause a  malfunction. 
¸Do not place the TV in hot, oily, 
humid or excessively dusty places. 
¸Do not install the TV where 
insects may enter. 
¸Do not install the TV where it may be exposed 
to mechanical vibration. 
¸Do not install the TV in a location where it may 
spear up, such as on or behind a pillar, or where 
you might bump your head on it. It may cause 
injury.
Preventing the TV from toppling over
To prevent the TV from toppling over, secure the 
TV to a wall or stand. 
Placement for watching
We suggest you to watch the TV at a distance 
of 3-7 times that of the screen height, and not 
in  excessive brightness. It is easy to cause eye 
fatigue if you watch TV for too long or in a dark 
room.  To  obtain  clear picture, do not expose the 
screen to direct illumination or  sunlight.  Use  spot 
lighting directed down from the ceiling if you can. 
Use in outdoor
This TV is not designed for 
outdoors installation. Do not 
expose the TV to rain, as it may 
result in a fire or an electric shock. 
Also, do not expose the TV to 
direct sunlight, as it may heat up 
and become damaged. 
Vehicle, ships and other vessels
Do not install this TV in a vehicle. 
Car accidents may cause the TV to 
fall down and cause injury. 
Do not install this TV in a ship or 
vessel. If the TV is exposed to 
seawater, it may cause a fire or 
damage the TV. 
Medical institutions
Do not place this TV  in  a  place where medical 
equipment is in use. 
It may cause the medical equipment to 
malfunction.

							VOLUME ADJUSTMENT
¸ Adjust the volume to avoid disturbing your 
neighbors. Sound carries easily at night. 
Therefore, we suggest you close the windows 
or use headphones. 
¸ When using headphones, adjust the volume 
to appropriate levels, or hearing damage may 
result. 
LCD SCREEN
¸ Although the LCD screen is made with high- 
precision technology and has effective 
pixels of 99.99% or more, black dots or 
bright points or light (red, blue, or green) 
may appear constantly on the LCD screen. 
This is a structural property of the LCD 
panel and is not a malfunction. 
¸ The LCD screen is made with high-precision 
technology. To achieve a high level of 
performance and picture quality, this TV’s 
backlight setting is set to maximize the 
brightness of the TV. However, uneven 
brightness may be observed when the LCD TV 
is viewed in a dark environment without an 
input source or a blank screen. This is a normal 
condition, not a malfunction of the TV. To 
improve this condition, change the Picture 
mode, Backlight setting, enable the Light 
Sensor, or turn on the Power management. 
¸ Avoid exposing the LCD screen surface to 
direct sunlight. It is likely to damage the LCD 
panel.
¸ Do not push or scratch the LCD screen, or place 
objects on top of the TV. The image may be 
uneven or the LCD panel may be damaged. 
¸ If the TV 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 improve as the temperature rises. 
¸ When still pictures are displayed continuously, 
ghosting may occur. It should disappear after a 
short period of time. 
¸ The screen and cabinet get warm when the TV 
is in use. This is a normal condition. 
¸ Spraying insect repellent with volatile material 
on the screen will cause damage. 
¸ Do not make prolonged contact with rubber 
or plastic material. 
Broken pieces
Do not throw anything at the TV. 
Doing so may break the screen glass 
and cause serious injury. 
If the surface of the TV cracks, unplug 
the AC power cord before touching the 
TV. Otherwise electric shock may result. 
Handling of broken glass and liquid 
crystal leakage
If the LCD panel gets damaged, crystalline liquid 
leakage may occur, or scattered broken glass may 
result. Do not touch broken glass or crystalline 
liquid which is toxic, with bare hands as cuts, 
poisoning  or skin irritation may occur. Also do not 
glass  fragments  or leaked crystalline liquid get 
into your eyes or  mouth.  Should  either  contacted 
your eyes or mouth, rinse the contacted area 
thoroughly with water and consult your doctor. 
SERVICING
Do not attempt to repair the TV 
yourself, since opening the cabinet 
may expose you to dangerous 
voltage or other hazards. Ask qualified service 
personnel to do the servicing for your TV. 
Replacement parts
When replacement parts  are required,  be  sure 
the service technician certifies in writing that 
he/she has used replacement parts specified by 
the  manufacturer that have the same 
characteristics as the original parts. 
Unauthorized substitutions may cause a  fire, 
an electric shock or other hazards. 
Safety check
Upon completion of repairs to the TV,  ask the 
service technician to perform routine safety 
checks (as specified by the manufacturer) to 
determine that  the TV is  safe  for  operating,  and 
to so certify. Ask a qualified service technician 
to dispose of the TV. 
For Customers in the United States
