· 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 monito\
r:
· 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 ey\
es. Be sure to
periodically look away from your monitor screen and focus on a far objec\
t to allow
your eye muscles to relax. If you have questions on eye fatigue or visua\
l 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 cons\
ider 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 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
· 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 ensur\
e 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 ch\
anges.
This is normal and the image can be readjusted using automatic image set\
up 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 Resoluti\
on
Display mode.

Understanding power management
Power management is invoked when the computer recognizes that you have n\
ot 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.

Caring for your monitor
Be sure to turn off the power before you perform any maintenance on the monitor.
Do not:· Apply water or liquid directly to your monitor.
· Use solvents or abrasives.
· Use flammable cleaning materials to clean your monitor or any other elec\
trical
equipment.
· Touch the screen area of your monitor with sharp or abrasive items. This type of
contact may cause permanent damage to your screen.
· Use any cleaner which contains an anti-static solution or similar additi\
ves. This
may harm the coating of the screen area.
Do:
· Lightly dampen a soft cloth with water and use this to gently wipe the c\
overs and
the screen.
· Remove grease or finger marks with a damp cloth and a little mild detergent.
Detaching the monitor stand
