Safety Precautions
Please note the following when setting up and using the display:
•DO NOT OPEN THE DISPLAY. There are no user serviceable parts inside and opening or
removing covers may expose you to dangerous shock hazards or other risks. Refer all
servicing to qualified service personnel.
• Do not spill any liquids into the cabinet or use your display near water.
• Do not insert objects of any kind into slots on the display, as they may touch dangerous voltage
points, which can be harmful or fatal or may cause electric shock, fire or equipment failure.
• Do not place any heavy objects on the power cord. Damage to the cord may cause shock or
fire.
• Do not place this product on a sloping or unstable cart, stand or table, as the monitor may fall,
causing serious damage to the display.
• Do not mount the display face up, face down or upside down for an extended period of time as
it may cause permanent damage to the screen.
• The power supply cord you use must have been approved by and comply with the safety
standards of your country. (Type H05VV-F 3G 1mm2 should be used in Europe)
• In UK, use a BS-approved power cord with melded plug having a black (13A) fuse installed for
use with this display.
• Do not place any objects on top of the display and do not use the display outdoors.
• Do not bend, crimp or otherwise damage the power cord.
• Do not use the display in high temperature, humid, dusty, or oily areas.
• If display glass is broken, do not come in contact with the liquid crystal and handle with care.
• Allow adequate ventilation around the display, so that heat can properly dissipate. Do not block
ventilated openings or place the display near a radiator or other heat sources.
• The power cable connector is the primary means of detaching the system from the power
supply. The monitor should be installed close to a power outlet, which is easily-accessible.
• Handle with care when transporting. Save packaging for transporting.
• Please clean the ventilation holes on the back of the display at least once a year to remove any
dust or dirt.
• Do not use the display under rapid temperature and humidity change condition or avoid cold air
from air-conditioning outlet directly, as it may shorten the lifetime of the display or cause
condensation. If condensation happens, let the display stand unplugged until there is no
condensation.
• The touch panel glass is not safety glass and is not laminated. As with other glass, the touch
panel glass may break into sharp pieces if misused, dropped, or otherwise subjected to a
substantial shock. If touch panel glass happens to break, please use care to avoid injury.
• DO NOT tap the monitor with hard or pointed objects, such as a pen or pencil.

8| Safety Information
Recommended Use
• For optimum performance, allow 20 minutes for warm-up.
• Position the display at a 90° angle to windows and other light sources to minimize glare and
reflections.
• Clean the display surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution
or glass cleaner.
• Adjust the display’s brightness, contrast and sharpness controls to enhance readability.
• Avoid displaying fixed patterns on the monitor for long periods of time to avoid image
persistence (after image effects).
Ergonomics
To realize the maximum ergonomic benefits, the following is recommended:
• Use the preset Size and Position controls with standard signals.
• Use the preset Color Setting.
• Use non-interlaced signals.
• Do not use primary color blue on a dark background, as it is difficult to see and may produce
eye fatigue due to insufficient contrast.
• Suitable for entertainment purposes at controlled luminous environments, to avoid disturbing
reflections from the screen.
Cleaning the LCD Panel
• When the liquid crystal panel is dusty, please gently wipe with a soft cloth.
• Do not rub the LCD panel with hard material.
• Do not apply pressure to the LCD surface.
• Do not use OA cleaner as it will cause deterioration or discolor on the LCD surface.
Cleaning the Cabinet
• Unplug the power supply
• Gently wipe the cabinet with a soft cloth
• To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet
and follow with a dry cloth.
NOTE
DO NOT clean with benzene thinner, alkaline detergent, alcoholic system detergent, glass
cleaner, wax, polish cleaner, soap powder, or insecticide. Rubber or vinyl should not be in
contact with the cabinet for an extended period of time. These types of fluids and materials can
cause the paint to deteriorate, crack or peel.

Power Management | 9
Power Management
To reduce power, the display supports three power-off methods, for different purposes.
Sleep Timer
• The user can set the timer to power off the display, regardless of the current source signal
status. Sleep Timer options in the OSD menu are: 5 mins, 15 mins, 30 mins, 60 mins, 90 mins,
120 mins, 180 mins, and OFF.
• This value will not be saved. It only executes once, and the default is OFF.
Power Save Timer
• This timer will power off the display when the current source has no signal. The adjustable
range of the Power Save Timer is 30 sec-300 sec, or OFF. This timer can be disabled in the
OSD menu.
• This value will be saved; the default is 300 sec.
• If the display is connected via VGA/HDMI1/HDMI2/DVI-D/DP and switches to standby as a
result of the Power Save Timer, the display will power on automatically if the signal from the
current source returns.
Schedule
• The user can set seven schedules to determine power-on times and power-off times
individually.
• The Schedule setting priority is higher than the Power Saving Timer. If the power-off time
setting in the Schedule is enabled, the system will disable the Sleep Timer automatically.
NOTE
For VGA/HDMI1/HDMI2/DVI-D/DP to support this function, please set the Detect Signal in
Standby function to ON in the OSD Menu.
NOTE
The Sleep Timer priority is the same as Power Save Timer; if both timers are enabled, the
power-off time of the display will depend on which timer is programmed to power off first.
NOTE
Not all video devices are guaranteed to support the auto power-on function when connected to
the display.
