Safety Precauons
• Read these instructions completely before using the equipment.
• Keep these instructions in a safe place.
• Heed all warnings and follow all instructions.
• Sit at least 18” / 45 cm from the monitor.
• When installing the monitor, please leave 4” / 10 cm of open space around the
monitor for ventilation safety purposes.
• Always handle the display with care when moving it.
• Always use cabinets or stands or installation methods recommended by the
manufacturer of the monitor set.
• Always use furniture that can safely support the monitor.
• Always ensure the monitor is not overhanging the edge of the supporting
furniture.
• Do not place the monitor where children are likely to be present.
• Always educate children about the dangers of climbing on furniture to reach the
monitor or related equipment.
• Always route and manage cords and cables connected to your monitor so they
cannot be tripped over, pulled, or grabbed.
• Exercise caution when removing the rear cover of the monitor. This monitor
contains high-voltage parts.
• Do not use this equipment near water. To reduce the risk of fire or electric
shock, do not expose the monitor to rain or moisture.
• Avoid exposing the monitor to direct sunlight or other sources of sustained heat.
Do not install near any heat sources such as radiators, heat registers, stoves, or
other devices (including amplifiers) that may increase the temperature of the
monitor to dangerous levels.
• Clean with a soft, dry cloth. If further cleaning is required, see the
“Maintenance” section in this guide for further instructions.
• Avoid touching the screen. Skin oils are difficult to remove.
• Do not touch, rub, or apply pressure to the monitor screen, as it may
permanently damage the screen.
• Do not place the monitor in an unstable location.
• Do not place the monitor on tall furniture (for example, cupboards or bookcases)
without anchoring both the furniture and the monitor to a suitable support.
• Do not place the monitor on cloth or other materials that may be located
between the product and supporting furniture.

4
• Place the monitor in a well-ventilated area. Do not place anything on the display
that prevents heat dissipation.
• Do not place heavy objects on the display, video cable, or power cord.
• Do not place items that might tempt children to climb, such as toys and remote
controls, on the top of the monitor or furniture on which the product is placed.
• If smoke appears, an abnormal noise, or a strange odor is present, immediately
switch the display off and contact your dealer or ViewSonic. It is dangerous to
continue using the display.
• Do not attempt to circumvent the safety provisions of the polarized or
grounding-type plug. A polarized plug has two blades with one wider than the
other. A grounding type plug has two blades and a third grounding prong. The
wide blade and the third prong are provided for your safety. If the plug does not
fit into your outlet, obtain an adaptor and do not attempt to force the plug into
the outlet.
• Please confirm the distribution system installed in the building. The system
should provide a circuit breaker rated at 120/240V, 20A.
• When connecting to a power outlet, DO NOT remove the grounding prong.
Please ensure grounding prongs are NEVER REMOVED.
• Protect the power cord from being treaded upon or pinched, particularly at the
plug, and at the point where it emerges from the equipment. Be sure that the
power outlet is located near the equipment so that it is easily accessible.
• Only use attachments/accessories specified by the manufacturer.
• Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the equipment. When a cart is used, use with caution
when moving the cart/equipment combination to avoid injury from tipping over.
• Unplug this equipment when it will be unused for long periods of time.
• Refer all servicing to qualified service personnel. Service will be required when
the unit has been damaged in any way, such as: if the power-supply cord or
plug is damaged, if liquid is spilled onto or objects fall into the unit, if the unit
is exposed to rain or moisture, or if the unit does not operate normally or has
been dropped.
• Excessive sound volume from ear-/headphones may cause hearing damage/
hearing loss.
• Adjustment of the volume control as well as the equalizer may increase the ear-/
headphones output voltage and therefore, the sound volume level.
• The factors influencing the ear-/headphones output other than those specified
by the manufacturer (e.g. operating system, equalizer software, firmware,
driver) may increase the ear-/headphone output voltage and therefore, the
sound volume level.

5
• Stability Hazard: The display may fall, causing serious personal injury or death.
To prevent injury, this display must be securely attached to the floor/wall in
accordance with the installation instructions.
• Fastening the monitor to a wall or fixed object using cordage or other restraining
devices can help support the weight of the monitor in order to prevent the
monitor from falling over.

NOTE:
• Restraining device/cordage should be able to withstand 100N force.
• Make sure the cordage is straightened, and any slack is removed. The back
of the device shall face the wall to ensure the device cannot tilt under
external force.
• Make sure the monitor does not tilt under external force at any height and
rotation angle of the device.
• If the existing monitor is going to be retained and relocated, the same
considerations as above should be applied.
