NOTE
NOTE 1: IMAGE PERSISTENCE
Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence occurs when residual or
“ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’
image persistence is not permanent, but constant images being displayed for a long period of time should be avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an
image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.
As with all personal display devices, PHILIPS recommends displaying moving images and using a moving panel saving at regular intervals
whenever the screen is idle or turning off the monitor when not in use.
Please set “POWER SAVE”, “PANEL SAVING”, “DATE AND TIME” and “SCHEDULE” functions to further reduce the risk of
Image persistence.
For long life use of Public Display
< Image Sticking of LCD Panel >
When LCD panel is operated continuously for long hours, a trace of electric charge remains near the electrode inside LCD, and residual or “ghost”
image of previous image may be observed. (Image Persistence)
Image Persistence is not permanent, but when fixed image is displayed for long period, ionic impurities inside LCD are accumulated along
the displayed image, and it is observed permanently. (Image Sticking)
< Recommendations >
For preventing the fast transition to Image Sticking, and for longer life usage of LCD, following are recommended.
1. Fixed image should not be displayed for long period, and changed to another images with short cycle.
2. In case a fixed image is display for a long time, it is advised to activate the pixel shift feature that will periodically move the image in four
directions
3. When no use, please turn off the monitor by remote control, or use Power Management Function of monitor or use Schedule
Function of monitor.
4. Reducing the environmental temperature is effective for long life use.
When Protection board (glass, acryl) is installed over the LCD surface, enclosed into the box / wall, or stack the monitor, please utilize the
temperature sensors inside monitor.
To reduce the environmental temperature, the monitor should be set Low Brightness or Cooling Fan “ON” by using Screen sever Function.
5. Please use "Panel saving Mode" of monitor.
NOTE 2: HOW TO SETUP SCHEDULE
Using the “SCHEDULE” function allows you to set up to seven different scheduled time intervals when the LCD Monitor will be activated.
You can select the time the monitor turns on and turns off, the day of week the monitor is activated, and which input source the monitor will
use for each scheduled activation period. A check mark in the box next to the number of the schedule indicates that the selected schedule is in
effect.
To select which schedule to set, use the up/down arrows to move the number (1 to 7) of the schedule.
Use the (+) and (-) buttons to move the cursor horizontally within the particular schedule. Use the ( ) and ( ) buttons to increase time
and select input port. The “SET” button is used to make a selection.
If you create a schedule but do not want to use a power on time, select “--” in the “ON” time slot.
If you do not want to use a power off time select “--” in the OFF time slot.
If there is no input selected (“--” showing in the input spot) the input from the previous schedule will be used.
The selection of EVERY DAY within a schedule takes priority over other schedules that are set up to operate weekly. When schedules
are overlapping, scheduled Power ON time has priority over scheduled Power OFF time.
If there are two schedules programmed for the same time, then the highest numbered schedule has priority. When the “SLEEP
TIMER” is set, the “SCHEDULE” function is disabled.
