NOTE 1: IMAGE PERSISTENCE 
y  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 im age 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. 
y   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 re mains, the monitor should be turned off for one hour to 
erase the image. 
y   As with all personal display devices, ViewSonic recommends displaying moving images and using a moving screen 
saver at regular intervals whenever the screen is id le or turning off the monitor when not in use. 
Please set “POWER SAVE”, “SCREEN SAVER”, “DATE &TIM E” 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 fo r long hours, a trace of electric charge remains near the electrode inside 
LCD, and residual or “ghost” image of previ ous image may be observed. (Image Persistence) 
Image Persistence is not permanent, but when fixed image is di splayed 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 peri od, and changed to another images with short cycle. 
2.  When no use, please turn off the monitor by remote c ontrol, or use Power Management Function of monitor or use 
Schedule Function of monitor. 
3.  Reducing the environmental temperat ure is effective for long life use. 
4.  Please use Screen Saver Mode of monitor. 
 
NOTE 2: HOW TO SETUP SCHEDULE 
y   Using the “SCHEDULE” function allows you to set up to  seven different scheduled time intervals when the LCD Monitor 
will be activated. 
y   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 per iod. A check mark in the box next to the number of the 
schedule indicates that the selected schedule is in effect. 
y   To select which schedule to set, use the up/down arro ws to move the number (1 to 7) of the schedule. 
y   Use the (+) and (-) buttons to move the cursor horizontally within the particular schedule. Use the ( S) and ( T) buttons 
to increase time and select input port. The  “SET” button is used to make a selection. 
y   If you create a schedule but do not want to use a  power on time, select “--” in the “ON” time slot. 
y   If you do not want to use a power off time select “--” in the OFF time slot. 
y   If there is no input selected (“--” showing in the input s pot) the input from the previous schedule will be used. 
y   The selection of EVERY DAY within a schedule takes priority  over other schedules that are set up to operate weekly. 
y   When schedules are overlapping, scheduled Power ON  time has priority over scheduled Power OFF time. 
y   If there are two schedules programmed for the same  time, then the highest numbered schedule has priority. 
When the “OFF TIMER” is set, the “SCHEDULE” function is disabled. 
 
NOTE 3: “PIP”, “POP” and “SIDE BY SIDE” 
The following table shows the combination of signal input s under which the “PIP” and “POP” modes function. These 
modes do not function however when the screen size is “CUSTOM” or “REAL”.

< Remote control numbering function > 
By connecting multiple CD4620 monitors using RS-232C cables, you can control any one monitor or all the monitors by 
one remote controller. 
1. Assign arbitrary ID number to each of mult
i-connected CD4620 monitors using MONITOR ID. 
ID numbers 1 to 26 are selectable. 
It is recommended to assign sequential ID numbers from 1 and up. 
2. The remote control mode of the first CD4620 monitor is se t to PRIMARY and those of the other monitors are set to 
SECONDARY. 
3. When you direct the remote controller at the remote c ontrol signal sensor of the PRIMARY monitor and press the 
DISPLAY button on the remote controller, the ID se lection OSD appears at the upper left of the screen. 
 
   
ID number of the currently viewed monitor 
 
 
Select the ID number of the monitor you want to control using the +/- button on the 
remote controller. 
The ID of the monitor you want to control is displayed at the upper left of its screen. 
By selecting ALL, you can control all the multi-connected monitors. 
 
4. Direct the remote controller at the remote c
ontrol signal sensor of the PRIMARY monitor. 
OSD appears on the monitor having the ID number you selected. 
 
NOTE: 
When the ID selection OSD is being displayed on the PR IMARY monitor, press the DISPLAY button on the remote 
controller again to cancel the ID selection  OSD and then control the monitor you selected. 
 
HINT:
