							v   Use adequate lighting for the type of work you are performing. 
v   Use the monitor brightness, contrast, and image adjustment controls, if 
equipped, to optimize the image on your screen to meet your visual preferences. 
v   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. 
v   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. 
v   Minor changes in posture can help avoid discomfort: The longer you sit and 
work with your computer, the more important it is to observe your working 
posture. Avoid assuming 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 
v   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.

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 1280 x 1024 at 60 Hz, which is the Native Resolution Display 
mode.

Understanding power management 
Power management is invoked when the computer recognizes that you have not 
used your mouse or keyboard for a user-definable period. There are several states 
as described in the table below. 
For optimal performance, switch off your monitor at the end of each working day, 
or whenever you expect to leave it unused for long periods during the day.
