Safety and Maintenance Guidelines
Important Safety Information
The power cord is designed for use with your monitor. To 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 diable 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 labeled 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

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.
For more detailed information on any of these topics, visit the Healthy Computing
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 study 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:
Copyright Lenovo 2011.
2-1
●
●
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.
Quick tips for healthy work habits
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 from 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.
