Safety Precau�ons
Please read the following Safety Precau�ons before you start using the device.
• Keep this user guide in a safe place for later reference.
• Read all warnings and follow all instructions.
• Ensure there is no direct airflow from air conditioning blowing on the display.
• Do not use the device near water. To reduce the risk of fire or electric shock, do
not expose the device to moisture.
• Avoid exposing the device 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
device to dangerous levels.
• When moving the device, be careful not to drop or bump the device on
anything.
• Do not place the device on an uneven or unstable surface. The device may fall
over resulting in an injury or a malfunction.
• Verify the wall can support the display's weight. If not, reinforce the wall before
installation.
• Do not place any heavy objects on the device or connection cables.
• If smoke, an abnormal noise, or a strange odor is present, immediately turn the
device off and call your dealer or ViewSonic®. It is dangerous to continue using
the device.
• 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 adapter and do not attempt to force the plug into
the outlet.
• 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. Ensure that the power outlet is located near the
equipment so that it is easily accessible.
• Only use attachments/accessories specified by the manufacturer.
• When a cart is used, use with caution when moving the cart/equipment
combination to avoid injury from tipping over.

• Do not cover the surface of the display with any material.
• Do not block the air circulation around the display.
• Keep flammable materials away from the display.
• 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 in the unit;
if the unit is exposed to moisture;
if the unit does not operate normally or has been dropped.
• Do not assemble the display by yourself.
• This panel is an advanced product that contains millions of pixels. You may
occasionally see pixel spots when viewing the screen. Since these deactivated
pixels are not a defect, the performance and reliability of the product is not
affected. For more information, please see page 87.

in the lower-right corner of the screen.
When enabled, the moderator can view a list of all connected screens in the le㿿
⿿oa俿ng window and can preview each par俿cipant’s screen and then select any
of par俿cipant’s screen and cast to the display’s main screen for presenta俿on. The
moderator can also control each par俿cipant’s screen, annotate on the display, and
remove unwanted par俿cipants by selec俿ng the close icon (X).

When enabled, the display’s screen will be broadcasted to all of the par俿cipant’s
connected screens simultaneously. The par俿cipants can only view the presenta俿on
contents un俿l the moderator disables the Broadcast func俿on.
By default, vCast is set to allow mul俿ple screen sharing, but can also be set to single
screen sharing. To do this, the moderator can select the Mul俿ple Screen Sharing
icon to switch to single screen sharing.
By default, vCast is set to let the moderator preview the par俿cipant’s screen
contents prior to sharing to the display. Selec俿ng the Preview Screen icon, the
Moderator can switch to see the par俿cipant’s name only.
By default, par俿cipants can use touch for collabora俿on a㿿er connec俿ng. The
moderator can enable/disable the touch func俿on of a par俿cipant by selec俿ng the
Touch icon in their window.
• Moderator Mode is supported on all vCastSender and AirPlay devices, but
mobile devices are limited to a “preview” func俿on. Addi俿onally, mobile
Android devices cannot cast sound out.
• When you cast your Windows/Mac/Chrome screen to the display, the
selected full screen unit will not be broadcasted back to your device to
avoid repe俿俿ve screen cas俿ng.
• The ac俿ve presenter can touch each of the par俿cipant’s screens to
remotely control cas俿ng devices.
• The number of mul俿-screen presenters on-screen depends on your
Windows CPU processor performance and router specica俿ons.

Maintenance
General Precau�ons
• The LED lights used in the modules are suscep俿ble to ESD (Electrosta俿c
discharge). To prevent damage to the LED lights, do not touch them with bare
hands or with conduc俿ve materials when handling.
• Wear an俿-sta俿c gloves and wrist strap when installing and servicing the display.
• It is recommended to regularly inspect all installed components.
• Do not bring objects close to the ven俿la俿on holes of the display. Burns or
personal injuries may occur if any body parts are brought too close.
• Be sure to power o� and disconnect all cables before moving the display. Moving
the display with its cables a忿ached may damage the cables and thus cause re
or electric shock.
• Power o� and disconnect the power plug from the wall outlet as a safety
precau俿on before performing any type of cleaning or maintenance.
Ini�al Opera�on
• If a new screen has been stowed for less than three months, it can be used at
normal brightness during its rst use.
• If a new screen has been stowed for more than three months, the brightness
should be set at 30% for its rst use and allowed to operate for two hours
con俿nuously. A㿿er two hours of use, power o� for 30 minutes. The new screen
is now ready for normal brightness usage.
Front Panel Cleaning Instruc�ons
• Use cool, compressed air to remove dust when the power is o�. If the dust
cannot be removed, the LED module should be replaced.
• Do not scratch and do not put pressure on the panel surface with ngers or any
abrasive object.
• Do not use vola俿le substances such as sprays, solvents, or thinners.
91
Page 92
Cabinet Cleaning Instruc�ons
• Do not allow water or detergent to come into contact with the surface of the
display. If water or moisture gets inside the unit, a system malfunc俿on or
electrical shock may occur.
• Do not scratch and do not put pressure on the cabinet with any abrasive objects
of any kind.
• Do not use vola俿le substances such as sprays, solvents, or thinners on the
cabinet.
• Do not place anything made from rubber or PVC near the cabinet for any
extended periods of 俿me.
Regular Use
• It is recommended to turn on the display at least once a month for more than
eight hours. During a wet and rainy season, it is recommended to turn on the
display at least once a week.
• Avoid using full white, full red, full blue, or full green content for an extended
period to avoid excessive power usage thus a�ec俿ng the LED lifespan.
