-  The TFT color LCD panel used in this monitor is made with 
the application of high precision technology. However, there 
may be minute points on the screen where pixels never light 
or are permanently lit. Also, if the screen is viewed from 
an acute angle there may be uneven colors or brightness. 
Please note that these are not malfunctions but common 
phenomena of LCDs and will not affect the performance of 
the monitor.
-  Do not display a still picture for a long period, as this could 
cause a residual image.
- Never rub or tap the monitor with hard objects.
-  Please understand that SHARP CORPORATION bears no 
responsibility for errors made during use by the customer or 
a third party, nor for any other malfunctions or damage to this 
product arising during use, except where indemnity liability is 
recognized under law.
-  This monitor and its accessories may be upgraded without 
advance notice.
-  Do not use the monitor where there is a lot of dust, where 
humidity is high, or where the monitor may come into contact 
with oil or steam. Do not use in an environment where 
there are corrosive gases (sulfur dioxide, hydrogen sulfide, 
nitrogen dioxide, chlorine, ammonia, ozone, etc.). As this 
could lead to fire.
-  Ensure that the monitor does not come into contact with 
water or other fluids. Ensure that no objects such as paper 
clips or pins enter the monitor as this could lead to fire or 
electric shock.
-  Do not place the monitor on top of unstable objects or in 
unsafe places. Do not allow the monitor to receive strong 
shocks or to strongly vibrate. Causing the monitor to fall or 
topple over may damage it.
-  Do not use the monitor near heating equipment or in places 
where there is likelihood of high temperature, as this may 
lead to generation of excessive heat and outbreak of fire.
-  Do not use the monitor in places where it may be exposed to 
direct sunlight.
-  Please be sure to constantly remove dust and garbage that 
has attached to the ventilation opening. If dust collects in the 
ventilation opening or the inside of the monitor, it may lead to 
excessive heat, outbreak of fire, or malfunction. 
Please request a cleaning of the inside of the monitor from 
an authorized SHARP servicing dealer or service center.
-  Images cannot be rotated on this monitor. 
When using in portrait orientation, you will need to prepare 
appropriately orientated content in advance.

be easily accessible.
The Power Cord

it, stretch it or over bend it. Also, do not add extension cords. 
Damage to the cord may result in fire or electric shock.
-  Do not use the power cord with a power tap. 
Adding an extension cord may lead to fire as a result of 
overheating.
-  Do not remove or insert the power plug with wet hands. 
Doing so could result in electric shock.
