Note: Adjust only those controls that are covered by the operating
instructions, since improper adjustment of other controls may
result in damage and will often require extensive work by a
qualified technician to restore the product to normal condition.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere and
obey all signs and instructions. Potentially explosive atmospheres include areas
where you would normally be advised to turn off your vehicle engine. Sparks in
such areas could cause an explosion or fire resulting in bodily injury or even
death. Switch off the device near gas pumps at service stations. Observe
restrictions on the use of radio equipment in fuel depots, storage and
distribution areas; chemical plants; or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often, but not always,
marked. They include below deck on boats, chemical transfer or storage
facilities, vehicles using liquefied petroleum gas (such as propane or butane),
and areas where the air contains chemicals or particles such as grain, dust or
metal powders.
Additional safety information
Your device and its enhancements may contain small parts. Keep them out of
the reach of small children.

Taking care of your vision
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive
room lighting, poorly focused screens, very small typefaces and low-contrast
displays could stress your eyes. The following sections provide suggestions on
how to reduce eyestrain.
Eyes
•Rest your eyes frequently.
•Give your eyes regular breaks by looking away from the monitor and
focusing on a distant point.
•Blink frequently to keep your eyes from drying out.
Display
•Keep your display clean.
•Keep your head at a higher level than the top edge of the display so your
eyes point downward when looking at the middle of the display.
•Adjust the display brightness and/or contrast to a comfortable level for
enhanced text readability and graphics clarity.
•Eliminate glare and reflections by:
•placing your display in such a way that the side faces the window or
any light source
•minimizing room light by using drapes, shades or blinds
•using a task light
•changing the display's viewing angle
•using a glare-reduction filter
•using a display visor, such as a piece of cardboard extended from the
display's top front edge
•Avoid adjusting your display to an awkward viewing angle.
•Avoid looking at bright light sources, such as open windows, for extended
periods of time.
Developing good work habits
Develop the following work habits to make your computer use more relaxing
and productive:
•Take short breaks regularly and often.
•Perform some stretching exercises.
•Breathe fresh air as often as possible.
•Exercise regularly and maintain a healthy body.

Installing/removing base
Note: Unpack the monitor and base rst. Carefully place the monitor face
down on a at surface - use a cloth pad to prevent scratching the screen.
1. Attach the monitor stand arm to
the base.
2. Secure the monitor to the arm of the
monitor. Close the base cover.
Note: If using a wall-mounting kit for mounting, we recommend using a VESA
mounting kit (100 mm × 100 mm) and M4 × 10 (L) mm screws to secure the
monitor to the wall.
3
Follow these instructions to remove the base from the monitor.
Note: Carefully place the monitor face down on a at surface - use a cloth
pad to prevent scratching the screen.

Connecting the power cord
(I) AC power
• Please rst ensure the power cord you are using is the correct type required in
your area.
• This monitor uses universal power and can run on 100/120 volts or
220/240 volts AC. The user does not need to make any adjustments.
• Plug one end of the power cord into the AC power input, and plug the other
end into an AC power outlet.
• Areas where 120 volts are used:
Use a UL-compliant power cord kit, including SVT-type leads and a 10-amp/125-
volt plug.
• Areas using 220/240 volts (outside the United States):
Use a power cord kit consisting of an H05VV-F cord and a 10 amp, 250 volt
plug. This power cord kit must meet the safety standards for the country where
you are installing the device.
(II) DC power supply
• Use the power adapter provided by the manufacturer, the specications are:
22 inch/24 inch Input: 100 - 240 V Output: 12 V 2.0 A
27 inch/32 inch Input: 100 - 240 V Output: 12 V 3.5 A
Safety precautions
• Avoid placing the monitor or any other heavy objects on the power adapter, as
this may cause re or electric shock.
• Do not expose the monitor to rain, excessive humidity or dust, as this may
cause re or electric shock.
• Do not cover slots or openings on the monitor to facilitate normal heat
dissipation. Place the monitor in a well-ventilated location.
• Avoid placing the display in front of an overly bright background, or where
direct sunlight or other light sources may shine on the display surface. Place
the monitor directly below your line of sight when staring straight ahead.
• Use extreme caution when handling the monitor.
• Please avoid hitting the display, and do not scratch the screen surface. The
screen is fragile.
• To prevent damage to the monitor, do not lift the monitor using the stand.
Cleaning the display
When you clean the monitor, follow the instructions carefully.
• Before cleaning, unplug the monitor's power adapter.
• Use a soft cloth to gently wipe the screen and the front and sides of the case.
• Never spill any liquid directly onto or into the screen or its case.
