SAFETY AND TROUBLESHOOTING INFORMATION
Safety precautions and maintenance
Read and follow these instructions when connecting and using your display:
Operation:
• Keep the display out of direct sunlight and away from stoves or any other heat sources.
• Remove any object that could fall into ventilation holes or prevent proper cooling of the display’s electronics.
• Do not block the ventilation holes on the cabinet.
• When positioning the display, make sure the power plug and outlet are easily accessible.
• When turning off the display by detaching the power cord, wait 6 seconds before re-attaching the power cord for
normal operation.
• Ensure the use of an approved power cord provided by Philips at all times. If your power cord is missing, please contact
your local service center.
• Do not subject the display to severe vibration or high impact conditions during operation.
• Do not knock or drop the display during operation or transportation.
Maintenance:
• To protect your display from possible damage, do not put excessive pressure on the LCD panel. When moving your
display, grasp the frame to lift; do not lift the display by placing your hand or fingers on the LCD panel.
• Unplug the display if you are not going to use it for an extensive period of time.
• Unplug the display 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 display.
• To avoid the risk of shock or permanent damage to the set, do not expose the display to dust, rain, water or an
excessively moist environment.
• If your display becomes wet, wipe it with dry cloth as soon as possible.
• If a foreign substance or water gets in your display, turn the power off immediately and disconnect the power cord.
Then remove the foreign substance or water, and send the unit to the maintenance center.
• Do not store or use the display in locations exposed to heat, direct sunlight or extreme cold.
• In order to maintain the best performance of your display and ensure a longer lifetime, we strongly recommend using
the display in a location that falls within the following temperature and humidity ranges.
- Temperature: 0 ~ 40 C 32-104 F
- Humidity: 20-80% RH
IMPORTANT: Always activate a moving screen saver program when you leave your display unattended. Always activate a
periodic screen refresh application if the unit will display unchanging static content. Uninterrupted display of still or static
images over an extended period may cause “burn in”, also known as “after-imaging” or “ghost imaging”, on your screen.
This is a well-known phenomenon in LCD panel technology. In most cases, the “burned in” or “after-imaging” or “ghost
imaging” will disappear gradually over a period of time after the power has been switched off.
WARNING: Severe "burn-in" or "after-image" or "ghost image" symptoms will not disappear and cannot be repaired.
This is also not covered under the terms of your warranty.
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.
