Safety, Warning, and Notice
To prevent potential dangers and prolong the service life of the TV, please observe the following points
when installing, operating, and cleaning the TV.
For wall mounting, have a qualified and
experienced technician mount it safely.
Use only a recommended wall bracket
(optional accessory) for this TV and
ensure that the bracket is securely screw
fixed to the wall structure, and not just
the wall render, lining or cladding.
Do not place the TV near water, like a
spa or pool, or in a position which will
allow the splashing or spraying of water
onto the display.
Do not place the TV near or above sources
of heat, such as radiators, heaters, fuel
stoves and other heat-generating items
(including audio amplifiers).
Observe all warnings and cautions as
labeled on the TV.
Do not place the TV in direct sun or spot
lighting will shine onto the TV.
Do not place the TV on an uneven, sloping
or unstable surface (such as a trolley)
where it may fall and cause damage to
itself or others.
For wall mounting, allow appropriate
space on top for attaching the TV to the
wall bracket.
Do not place the TV in an enclosed place
without allowing for ventilation.
If recessed into a wall opening, you must
leave appropriate free space both top
and bottom for mounting and removing
the TV.
All Liquid Crystal Display (LED) screens
have a very thin protective layer of glass
which is liable to marking or scratching,
and cracking if struck or pressured. The
liquid crystal substrate is also liable to
damage under excessive force or extreme
temperatures. Please handle with care.
Do not cover or block the vents and
openings while the TV is switched on.
To prevent the spread of fire, keep candles
or other open flames away from the TV at
all times.
Do not insert your fingers or any foreign
objects into the hinge and its surrounding
area to avoid possible injury to you or
damage to the TV.
Do not apply excessive force or place
heavy stuff on the TV to avoid possible
damage.
Only use the power cord supplied with the TV. Never use a power cord which appears damaged or
frayed, or change the plug type on the power cord.
Use only a properly grounded plug and receptacle. -- An improper ground may cause electric shock or
equipment damage (Class l Equipment only).
Be aware of the total loading when using extension cords or multiple outlet power boards.
This TV has no power switch. When installing the TV, incorporate a readily accessible disconnect device
in the fixed wiring, or connect the power cord to socket-outlet which must be provided near the TV and
easily accessible. If a fault should occur during operation of the unit, operate the disconnect device to
switch the power supply off, or disconnect the power cord.
This TV has been engineered and manufactured with the highest priority on safety, however, IMPROPER
HANDLING OR USE CAN RESULT IN POTENTIAL ELECTRICAL SHOCK OR FIRE HAZARD. Please
handle this TV with care. If damaged, turn off the power and unplug the power cord from the TV.
Transport the TV to your nearest BenQ authorized service center for repair.
There are no user serviceable parts in this TV. Never unscrew or remove any covers. There are
dangerous voltages inside. Turn off the power and unplug the power cord before moving the TV.

Safety, Warning, and Notice
Care and cleaning information
Always turn off and disconnect the TV from the mains power before cleaning.
Do not use cream, liquid, aerosol or spray cleaners. Use only a slightly damp well wrung-out (drip-free)
and lint-free, clean soft cloth and lightly wipe the TV.
If necessary, use a pH-neutral liquid dish-washing detergent diluted with water on a separate clean lintfree cloth to remove oil or grease marks. Wipe over again with a clean dry lint-free cloth to remove any
smear marks.
When cleaning the TV (including the frame around the screen), please use a proper cleaning tool
harmless to the materials used by the TV in order to avoid possible scratches or damages.
Under close examination and in certain circumstances, you may notice that a few non-active pixels
appear on the screen as a fixed point of color. Please note that this does not affect the performance of
your product as it is usually not visible at normal viewing distances.
If the TV is not going to be used for an extended period of time (like when you are going away for
holidays), it should be switched off and unplugged from the wall outlet. You should also consider removing
the batteries from the remote control (as they may leak).
The TV is not suitable for installation on certain transportation vehicles (such as cars, yachts, and so on)
to avoid possible damage to the TV because of vibration.
LED (Liquid Crystal Display) screens, like plasma (PDP) and conventional CRT (Cathode Ray Tube)
screens, are also susceptible to "screen burn-in" or"image retention" which can be found on the screen
as visible fixedlines and shades and cannot be removed. To avoid such permanent damage to the screen,
please take the following preventive measures when using your TV:

Care and cleaning information
Safety notice for batteries
Safety notice for remote control
(1) Avoid displaying still images (like On-Screen Display menus, TV station logos, fixed/inactive text or
icons) for more than two hours.
(2) Change the aspect ratio from time to time. Fill the entire screen with the image and eliminate the
black bars whenever possible. Avoid displaying images in 4:3 aspect ratio over a long period of time,
otherwise there may be visible burn marks on the screen as two vertical lines.
(3) Turn on the ECO Mode function when displaying PC input image.
(4) This TV is designed for home use only. Do not use it as a commercial display in public areas.Please note
that the product warranty does not cover any screen damages that result from the failure to take the
measures above.
Please note that the product warranty does not cover any screen damages that result from the failure to
take the measures above.
Many of the electronic components used by the TV contain high tension coils, and thus inductance occur when circuits pass
through these components. This inductance is a normal physical phenomenon, which can be found in many electronic devices in daily
life such as computers and fluorescent lights. Therefore, there is no concern or worry about the use and safety of this TV.
The use of the wrong type of batteries may cause chemical leaks or explosion. Please note the following:
Always ensure that the batteries are inserted with the positive and negative terminals in the correct
direction as shown in the battery compartment.
Different types of batteries have different characteristics. Do not mix different types.
Do not mix old and new batteries. Mixing old and new batteries will shorten battery life or cause
chemical leaks from the old batteries.
When batteries fail to function, replace them immediately.
Chemicals which leak from batteries may cause skin irritation. If any chemical matter seeps out of the
batteries, wipe it up immediately using a dry cloth, and replace the batteries as soon as possible.
Due to varying storage conditions, the battery life for the batteries included with your TV may be
shortened. Replace them within 3 months or as soon as you can after initial use.
