Troubleshooting Information and Safety
Safety precautions and maintenance
WARNING: Use of controls, adjustments or
procedures other than those specified in this
documentation may result in exposure to shock,
electrical hazards and/or mechanical hazards.
Read and follow these instructions when connecting and using
your computer monitor:
a.
To protect your display from possible damage, do not put
excessive pressure on the LCD panel. When moving your
monitor, grasp the frame to lift; do not lift the monitor by
placing your hand or fingers on the LCD panel.
b.
Unplug the monitor if you are not going to use it for
an extensive period of time.
c.
Unplug the monitor if you need to clean it with a slightly
damp cloth. The screen may be wiped with a dry cloth when
the power is off. However, never use alcohol, solvents or
ammonia-based liquids.
d.
Consult a service technician if the monitor does not operate
normally when you have followed the instructions in this
manual.
e.
The casing cover should be opened only by qualified service
personnel.
f.
Keep the monitor out of direct sunlight and away from
stoves or any other heat source.
g.
Remove any object that could fall into the vents or prevent
proper cooling of the monitor's electronics.
h.
Do not block the ventilation holes on the cabinet.
i.
Keep the monitor dry. To avoid electric shock, do not
expose it to rain or excessive moisture.
j.
When positioning the monitor, make sure the power plug
and outlet are easily accessible.
k.
If turning off the monitor by detaching the power cable or DC
power cord, wait for 6 seconds before attaching the power
cable or DC power cord for normal operation.
l.
To avoid the risk of shock or permanent damage to the set,
do not expose the monitor to rain or excessive moisture.
m. IMPORTANT: Always activate a screen saver program during
your application. If a still image in high contrast remains on
the screen for an extended period of time, it may leave an
'after-image' or 'ghost image' on front of the screen. This is a
well-known phenomenon that is caused by the shortcomings
inherent in LCD technology. In most cases, the afterimage will
disappear gradually over a period of time after the power has
been switched off. Be aware, that the afterimage symptom
cannot be repaired and is not covered under warranty.
o.
Warning for lifting monitor - Do not use the area underneath
the logo cover to grip or lift the monitor. Placing weight on
the logo cover can cause it to break away from the body and
cause the monitor to fall. When lifting the monitor, place one
hand under the monitor's frame.
*Consult a service technician if the monitor does not operate
normally when the operating instructions given in this manual
have been followed.
