Safety and Maintenance Guidelines
Important Safety Information
The power cord is designed for use with your monitor. Don’t use a different cord, use only a power source and
connection compatible with this monitor.
WARNING: Always connect your monitor, the computer, and other equipment to a grounded (earthed) power
outlet. To reduce the risk of electric shock or damage to your equipment, do not disable the power cord grounding
feature. The grounding plug is an important safety feature.
WARNING: For your safety, be sure that the grounded power outlet you plug the power cord into is easily
accessible to the operator and located as close to the equipment as possible. To disconnect power from the
equipment, unplug the power cord from the power outlet by grasping the plug firmly. Never pull on the cord.
CAUTION: To protect your monitor, as well as your computer, connect all power cords for your computer and its
peripheral devices (such as a monitor, printer, or scanner) to a surge protection device such as a power strip with
surge protection or uninterruptible power supply (UPS). Not all power strips provide surge protection; the power
strips must be specifically labelled as having this ability. Use a power strip whose manufacturer offers a damage
replacement policy, so you can replace your equipment if surge protection fails.
CAUTION: A certified power supply cord has to be used with this equipment. The relevant national installation
and/or equipment regulations shall be considered. A certified power supply cord not lighter than ordinary
polyvinyl chloride flexible cord according to IEC 60227 (designation H05VV-F 3G 0.75mm² or H05VVH2-F2 3G
0.75mm²) shall be used. An alternative flexible cord is synthetic rubber.
Safety Precautions
■Use only a power source and connection compatible with this monitor, as indicated on the label/back
plate of the monitor.
■Be sure the total ampere rating of the products connected to the outlet does not exceed the current rating of the
electrical outlet, and the total ampere rating of the products connected to the power cord does not exceed the
rating of the power cord. Look on the power label to determine the ampere rating (Amps or A) for each device.
■ Install your monitor near a power outlet that you can easily reach. Disconnect the monitor by grasping the plug
firmly and pulling it from the outlet. Never disconnect the monitor by pulling the cord.
■ Do not allow anything to rest on the power cord. Do not walk on the cord.
■ While using VESA mount application, the AC Inlet must face to down side. Do not face any other position.
Maintenance Guidelines
To enhance the performance and extend the life of your monitor:
■ Do not open your monitor cabinet or attempt to service this product yourself. If your monitor is not operating
properly or has been dropped or damaged, contact your Lenovo authorized dealer, reseller, or service provider.
■ Adjust only those controls that are described in the operating instructions.
■ Turn your monitor off when not in use. You can substantially increase the life expectancy of the monitor by using
a screen saver program and turning off the monitor when not in use.
■ Keep your monitor in a well-ventilated area, away from excessive light, heat, or moisture.
■ Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked or covered.
Never push objects of any kind into cabinet slots or other openings.
■ Unplug the monitor from the power outlet before cleaning. Do not use liquid cleaners or aerosol cleaners.
■ Do not drop the monitor or place it on an unstable surface.
■ When removing the monitor base, you must lay the monitor face down on a soft area to prevent it from getting

Chapter 2 Adjusting and using your monitor
This section will give you information on adjusting and using your monitor.
Comfort and accessibility
Good ergonomic practice is important to get the most from your personal computer and
to avoid discomfort. Arrange your workplace and the equipment you use to suit your
individual needs and the kind of work that you perform. In addition, use healthy work
habits to maximize your performance and comfort while using your computer.
Arranging your work area
Use a work surface of appropriate height and available working area to allow you to
work in comfort.
Organize you work area to match the way you use materials and equipment. Keep your
work area clean and clear for the materials that you typically use and place the items
that you use most frequently, such as the computer mouse or telephone, within the
easiest reach.
Equipment layout and setup play a large role in your working posture. The following
topics describe how to optimize equipment setup to achieve and maintain good
working posture.
Positioning and viewing your monitor
Position and adjust your computer monitor for comfortable viewing by considering the
following items:
●Viewing distance:
Optimal viewing distances for monitors range from approximately 510mm to 760mm
(20 in to 30 in) and can vary depending on ambient light and time of day. You can
achieve different viewing distances by repositioning your monitor or by modifying
your posture or chair position. Use a viewing distance that is most comfortable for
you.
●Monitor height:
Position the monitor so your head and neck are in a comfortable and neutral (vertical,
or upright) position. If your monitor does not have height adjustments, you might
have to place books or other sturdy objects under the base of the monitor to achieve
the desired height. A general guideline is to position the monitor such that the top of
the screen is at or slightly below your eye-height when you are comfortably seated.
However, be sure to optimize your monitor height so the line of site between your
eyes and the center the monitor suits your preferences for visual distance and
comfortable viewing when your eye muscles are in a relaxed stated.
●Tilt :
Adjust the tilt of your monitor to optimize the appearance of the screen content and to
accommodate your preferred head and neck posture.
●General location:
Position your monitor to avoid glare or reflections on the screen from overhead
lighting or nearby windows.
The following are some other tips for comfortable viewing of your monitor:
●Use adequate lighting for the type of work you are performing.
●Use the monitor brightness, contrast, and image adjustment controls, if equipped, to
optimize the image on your screen to meet your visual preferences.
●Keep your monitor screen clean so you can focus on the screen’s contents.
Any concentrated and sustained visual activity can be tiring for your eyes. Be sure to
periodically look away from your monitor screen and focus on a far object to allow your
eye muscles to relax. If you have questions on eye fatigue or visual discomfort, consult a
vision care specialist for advice.
Chapter 2 Adjusting and using your monitor 2-1

Quick tips for healthy work habits
Eye Strain
The following information is a summary of some important factors to consider to help
you remain comfortable and productive while you use your computer.
●Good posture starts with equipment setup:
The layout of your work area and the setup of your computer equipment have a large
effect on your posture while using your computer. Be sure to optimize the position
and orientation of your equipment by following the tips outlined in “Arranging your
work area ” on page 2-1 so you can maintain a comfortable and productive posture.
Also, be sure to use the adjustment capabilities of your computer components and
office furniture to best suit your preferences now and as your preferences change over
time.
●Minor changes in posture can help avoid discomfort:
The longer you sit and work in front of your computer, the more important it is to
observe your working posture. Avoid as summing any one posture for an extended
period of time. Periodically make minor modifications in your posture to help deter
any discomforts that might arise. Make use of any adjustments that your office
furniture or equipment provide to accommodate changes in posture
●Short, periodic breaks help ensure healthy computing:
Because computing is primarily a static activity, it is particularly important to take
short breaks from your work. Periodically, stand up in front of your work area, stretch,
walk for a drink of water, or otherwise take a short break from using your computer.
A short break from work gives your body a welcome change in posture and helps to
ensure you remain comfortable and productive while you do work.
●Break Times
Computer users should take some time away from the screen especially if working for
prolong hours. Generally, it is recommended to take short breaks (5 – 15 min.) after
1 –2 hours of continuous computer works. Taking short and frequent breaks is more
advised than longer breaks.
●Looking at Distant Objects
Users often blink less when in front of monitor screen. To minimize eye strain and
dryness, users should rest the eye periodically by focusing on objects that are far away.
●Eye Exercises
1. Alternate looking up and looking down while keeping the body and head upright.
2. Slowly roll your eyes to look to the left and right.
3. Roll eyes to look at objects on the upper right corner and then on lower right. Do
same thing to look at objects on the upper left and lower left.
Low Blue Light
Concerns on blue light affecting eye health have risen over the years. Blue light have
wavelength between 300 nm to 500 nm. The monitors have a factory setting that reduces
blue light emissions. Users can enable low blue light mode on these monitors from the
OSD settings.

Selecting a supported display mode
The display mode the monitor uses is controlled by the computer. Therefore, refer to your computer
documentation for details on how to change display modes.
The image size, position and shape might change when the display mode changes. This is normal and the image
can be readjusted using automatic image setup and the image controls.
Unlike CRT monitors, which require a high refresh rate to minimize flicker, LCD or Flat Panel technology is
inherently flicker-free.
Note: If your system has previously been used with a CRT monitor and is currently configured to a display
mode outside the range of this monitor, you may need to re-attach the CRT monitor temporarily until you have
re-configured the system; preferably to 1366x768 at 60Hz, which is the Native Resolution Display mode.
The display modes shown below have been optimized at the factory.
