Operation
 Please keep the monitor out of direct
sunlight, very strong bright lights and away 
from any other heat source. Lengthy 
exposure to this type of environment may 
result in discoloration and damage to the 
monitor.
 Remove any object that could fall into
ventilation holes or prevent proper cooling 
of the monitor’s electronics.
 Do not block the ventilation holes on the
cabinet.
 When positioning the monitor, make
sure the power plug and outlet are easily 
accessible.
 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.
 Please use approved power cord provided
by Philips all the time. If your power cord 
is missing, please contact with your local 
service center. (Please refer to Customer 
Care Consumer Information Center)
 Do not subject the monitor to severe
vibration or high impact conditions during 
operation.
 Do not knock or drop the monitor during
operation or transportation.
Maintenance
 To protect your monitor from possible
damage, do not put excessive pressure 
on the monitor panel. When moving your 
monitor, grasp the frame to lift; do not lift 
the monitor by placing your hand or fingers 
on the monitor panel.
 Unplug the monitor if you are not going to
use it for an extensive period of time.
 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 organic solvent, 
such as, alcohol, or ammonia-based liquids 
to clean your monitor.
 To avoid the risk of shock or permanent
damage to the set, do not expose the 
monitor to dust, rain, water, or excessive 
moisture environment.
 If your monitor gets wet, wipe it with dry
cloth as soon as possible.
 If foreign substance or water gets in
your monitor, please turn the power off 
immediately and disconnect the power 
cord. Then, remove the foreign substance 
or water, and send it to the maintenance 
center.
 Do not store or use the monitor in
locations exposed to heat, direct sunlight or 
extreme cold.

of your monitor and use it for a longer 
lifetime, please use the monitor in a 
location that falls within the following 
temperature and humidity ranges.
