• 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

• 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

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.
• Disconnect the power plug from the AC outlet if the device is not being used for
a long period of time.

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.
