Securing the monitor to a wall (optional)  
WARNING  
Procedure may differ depending on the model.  
If the monitor is not positioned in a  
sufficiently stable location, there is a  
danger that it will fall. Many injuries,  
particularly to children, can be avoided by  
taking simple precautions such as:  
»»Using cabinets or stands  
recommended by the manufacturer.  
»»Only using furniture that can safely  
support the monitor.  
»»Ensuring the monitor is not  
overhanging the edge of the supporting  
furniture.  
»»Not placing the monitor on tall furniture  
(for example, cupboards or bookcases)  
without anchoring both the furniture  
and the monitor to a suitable support.  
»»Not placing cloth or other materials  
between the monitor and supporting  
furniture.  
»»Educating children about the dangers  
of climbing on furniture to reach the  
monitor or its controls.  
1
Insert and tighten the eyebolts, or brackets  
and bolts on the back of the monitor.  
- If there are already bolts inserted in the  
eyebolts’ position, remove the other bolts  
first.  
2 Mount the wall brackets with the bolts to the  
wall. Match the location of the wall bracket  
and the eyebolts on the rear of the monitor.  
3 Connect the eyebolts and wall brackets  
tightly with a sturdy cord.  
Make sure the securing cord is horizontal  
with the flat surface.  
CAUTION  
Make sure that children do not climb on or  
hang from the monitor.  
NOTE  
Use a platform or cabinet that is large  
and strong enough to support the monitor  
securely.  
Brackets, bolts, and cords are sold  
separately. You can obtain additional  
accessories from your local retail store.

Tips for using USB storage devices  
Only a USB storage device can be recognized.  
A USB device does not work effectively when it is connected via a USB hub.  
A USB storage device using an automatic recognition program may not be recognized.  
A USB storage device using its own driver may not be recognized.  
The recognition speed of a USB storage device may depend on each device.  
Please do not turn off the display or unplug the USB storage device when the connected device is  
working. If the USB storage device is suddenly disconnected, the stored files or the device itself may  
be damaged.  
Please do not connect a USB storage device which was modified to work on a PC. The device may  
cause the monitor to malfunction or the content fail to be played. Use only a USB storage device  
which contains normal music, image or video files.  
A USB storage device formatted as a utility program not supported by Windows may not be  
recognized.  
A USB storage device (over 0.5 A) which requires an external power supply must be connected to a  
power supply separately. If it is not, the device may not be recognized.  
Please connect the USB storage device using the cable provided by the device manufacturer.  
Some USB storage devices may not be supported or operate smoothly.  
File alignment method of USB storage devices is similar to that of Window XP and filenames can  
recognize up to 100 English characters.  
Back up important files regularly as data stored on a USB storage device may be damaged. We will  
not be responsible for any data loss.  
If the USB HDD does not have an external power source, the USB device may not be detected. To  
ensure the device is detected, connect the external power source.  
- Please use a power adapter for an external power source. We do not provide a USB cable for an  
external power source.  
If your USB storage device has multiple partitions, or if you use a USB multi-card reader, you can use  
up to four partitions or USB storage devices.  
If a USB storage device is connected to a USB multi-card reader, its volume data may not be  
detected.  
If the USB storage device does not work properly, disconnect and reconnect it.  
Detection speed differs from device to device.  
If the USB storage device is connected in Standby Mode, the specific hard disk will automatically be  
loaded when the display is turned on.  
The recommended capacity is 1 TB or less for a USB external hard drive and 32 GB or less for USB  
memory stick.  
Any device with more than the recommended capacity may not work properly.  
If a USB external hard drive with an “Energy Saving” function does not work, try turning the hard drive  
off and on again.  
USB storage devices below USB 2.0 are also supported but may not function correctly in the Videos.  
A maximum of 999 sub-folders or files can be recognized under one folder.

monitor is identified by a Set ID. If you assign  
the PICTURE ID using the remote control, only  
displays with matching PICTURE ID and Set ID  
can be controlled remotely.

Tips for Wireless Network Setting  
Wireless networks can be subject to interference from other devices operating at a frequency of 2.4  
GHz (wireless phones, Bluetooth devices or microwave ovens). There may also be interference from  
devices with a frequency of 5 GHz, same as other Wi-Fi devices.  
The surrounding wireless environment can cause the wireless network service to run slowly.  
If you do not turn off the entire local home network, network traffic may occur on some devices.  
For an AP connection, an access point device that supports wireless connection is required and the  
wireless connection feature must be enabled on the device. Contact your service provider regarding  
availability of wireless connection on your access point.  
Check the SSID and security settings of the AP for AP connection. Refer to the appropriate  
documentation for SSID and security settings of the AP.  
Invalid settings on network devices (wired/wireless line sharer, hub) can cause the monitor to run  
slowly or not operate properly. Install the devices correctly according to the appropriate manual and  
set the network.  
Connection method may differ according to the AP manufacturer.

[Command1][Command2][ ][Set ID][ ][Data][Cr]  
* [Command1]: identifies between the factory setting and the user setting modes.  
* [Command2]: controls monitor sets.  
* [Set ID]: Used for selecting a set you want to control. A unique Set ID can be assigned to each set  
ranging from 1 to 1000(01H~3E8H) under Settings in the OSD menu.  
Selecting '00H' for Set ID allows the simultaneous control of all connected monitors.  
* [Data]: Transmits command data.  
Data count may increase depending on the command.  
* [Cr]: Carriage Return. Corresponds to '0x0D' in ASCII code.  
* [ ]: White Space. Corresponds to '0x20' in ASCII code.  
Acknowledgement  
[Command2][ ][Set ID][ ][OK/NG][Data][x]  
* The Product transmits ACK (acknowledgement) based on this format when receiving normal data. At  
this time, if the data is FF, it indicates the present status data. If the data is in data write mode, it returns  
the data of the PC computer.  
* If a command is sent with Set ID '00' (=0x00), the data is reflected to all monitor sets and each monitor  
set does not send an acknowledgement (ACK).  
* If the data value 'FF' is sent in control mode via RS-232C, the current setting value of a function can  
be checked (only for some functions).  
*Some commands are not supported depending on the model.
