The LCD unit is produced with high-precision manufacturing techniques. Nevertheless,
some pixels may occasionally misfire or appear as black or red dots. This has no effect on
the recorded image and does not constitute a malfunction.
Tip s a n d in fo rm a t io n fo r co m fo rt a b le u se
Computer users may complain of eyestrain and headaches after prolonged use. Users are
also at risk of physical injury after long hours of working in front of a computer. Long
work periods, bad posture, poor work habits, stress, inadequate working conditions,
personal health and other factors greatly increase the risk of physical injury.
Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis
or other musculoskeletal disorders. The following symptoms may appear in the hands,
wrists, arms, shoulders, neck or back:
•
•
•
•
•
numbness, or a burning or tingling sensation
aching, soreness or tenderness
pain, swelling or throbbing
stiffness or tightness
coldness or weakness
If you have these symptoms, or any other recurring or persistent discomfort and/or pain
related to computer use, consult a physician immediately and inform your company’s
health and safety department.
The following section provides tips for more comfortable computer use.
Fin d in g yo u r co m fo rt zo n e
Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest,
or raising your sitting height to achieve maximum comfort. Observe the following tips:
•
•
•
•
•
refrain from staying too long in one fixed posture
avoid slouching forward and/or leaning backward
stand up and walk around regularly to remove the strain on your leg muscles
take short rests to relax your neck and shoulders
avoid tensing your muscles or shrugging your shoulders
EN-3
•
•
install the external display, keyboard and mouse properly and within comfort
able reach
if you view your monitor more than your documents, place the display at the
center of your desk to minimize neck strain
Ta kin g ca re o f yo u r visio n
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.
De ve lo p in g g o o d w o rk h a b it s
Develop the following work habits to make your computer use more relaxing and
productive:
•
•
•
•
Take short breaks regularly and often.
