NOTIFICATION

This device has been tested and found to
comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide
reaso nable protect ion against har mful
interference in a residential installation. This

may cause harmful interference to radio
communications.
However, th e r e is no guaran tee that
interference will not occur in a particular
installation. If this equipment does cause
harmful interference to radio or television
reception, which can be determined by
turning the equipment off and on, the user is
encouraged to try to correct the interference
by one or more of the following measures:

◊ Reorient or relocate the receiving antenna.
◊ Increase the separation between the device

and receiver.

◊ Connect the device into an outlet on a

circuit different from that to which the
receiver is connected.

◊ Consult the dealer or an experienced

radio/TV technician for help.

Pursuant to FCC regulations, be
cautioned that any changes or

modications not expressly approved in

this manual could void your authority to
operate this equipment.

Safety

◊ Operate the TV only on 120 – 240 V AC.
◊ Use the AC power cord specied by

◊ 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,
moisture 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 re 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 re 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 qualied service

personnel to do the servicing for your TV.

Replacement parts

When replacement parts are required, be sure the

service technician certies in writing that he/she has
used replacement parts specied 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

qualied service technician to dispose of the

TV.

Getting Started

Mounting ViewSonic LCD TV to the wall

The LCD TV can be used in a free standing position or wall-mounted. Before installing the
product to the wall, please consider the following guidelines:

• Due to safety concerns, if the VESA mounting kit is purchased separately please make
sure the mounting kit is UL-Listed, and replaceable only by service personnel.

• Read the Important Safety Instructions, at the start of this manual.

• Do not install in a moist or wet environment. This equipment is intended for indoor use.

• Do not install near heat source, or strong magnetic elds.

• Use only ViewSonic approved wall-mounting brackets to support the LCD TV weight.

• Before attaching the wall mount plate to the back cover, ensure the product is working.

• If your LCD TV is already set up for free-standing operation, you need to rst remove the

stand before mounting the device to the wall.

To attach the wall-mount bracket to LCD TV safely, please use the following guidelines:

• Disconnect the power and any other cables that might hinder moving the LCD TV.

• Set the LCD TV on a table or work surface, placing the screen face down on a towel or

woolen blanket to protect the screen surface from damage while installing plate.

• Before installing the LCD TV on the wall, ensure you have recorded the product serial
number on page (i) of the User Guide, as you will need the serial number to request
service should there be a service need.

• Install the wall mount plate to the LCD TV using screws NO LONGER than 10mm, as
longer screws found in universal (non-ViewSonic) wall mount kits may damage the
power supply causing the unit to fail. The wall-mount screw type is M4 x L10.

• Mount the wall mount bracket to the wall ensuring use of proper screws to support the
installation. Ensure there is at least 3cm of space surrounding any air-vents of your
LCD TV to allow adequate cooling during operation.

• Hang the LCD TV wall mount plate to the wall mount bracket, completing installation.
Enjoy your ViewSonic LCD TV!
