Installing the Product
Installing on Wall
The electronic blackboard can be used in a wall-mounted format by securing it to a wall. To install it on a wall, first attach a wall mount support (optional) to the back of the product body. The wall mount support is a separate purchase and can be purchased from a nearby dealer. For more information on installing a wall mount support, see the installation guide provided with your wall mount support purchase.
Checking Wall Mount Support Specifications
When installing a wall mount support, you must use screws and brackets that comply with VESA (Video Electronics Standards Association) standard specifications.
⚠ Caution
- Disconnect the power cord first before moving or installing the product. There is risk of electric shock.
- Do not install the product on a ceiling or sloped wall. There is a risk of falling and injury.
- If you tighten the screws too tightly and damage the product, the warranty may not apply.
- Use screws and brackets for wall mounting that meet the VESA standard specifications. The warranty does not apply to the breakage or personal injury due to the use of incorrect components.
- Using screws longer than VESA standard specifications when installing a wall mount support may damage the interior of the product. In such cases, we do not take responsibility for any damage or issues that may arise with the product.
Installing the Product
Allow at least 10 cm of clearance from the wall for ventilation, and install the product with care to prevent it from falling. When purchasing a wall mount support, the installation guide and all necessary parts are included. A wall mount support can be purchased separately from a nearby dealer.

Using the Touch Pen
The touch pen can be used for various purposes, such as touching the screen to launch menus or to take notes, annotate, and draw on data.
Getting to Know the Touch Pen Functions
Two pens can be used simultaneously to write or draw together. Different
colours can be assigned to each pen. A pen has a 3 mm and 8 mm tip at each
end, allowing you to use two modes separately with one pen.
Note · If you press the pen on the screen for about 2 seconds and release it after you open a built-in PC (OPS), PDF viewer, or Word document, the same pop-up menu as when you right-click on the mouse will appear.
Storing the Pen
The touch pen can be attached to the magnetic touch pen holder to keep it in place, so you don’t lose it.
Replacing the Pen Tip
If the touch pen tip is worn or damaged, it must be replaced with a new tip.
- Remove the old tip by pulling on the end with tools such as tweezers.
- Slide the new tip into the pen body.
Note · To purchase additional touch pens or spare tips, contact LG Electronics.
Precautions for Use
Dust
The warranty will not cover any damage caused by using the product in an excessively dusty environment.
Afterimage
-
After-image appears when the product is turned off.
– Pixels may be damaged rapidly if a still image is displayed on the screen for a long period of time. Use the screen-saver function.
– Switching from a screen with high differences in luminance (black and white or grey) to a darker screen may cause an afterimage. This is normal due to the display characteristics of this product. -
When the LCD screen is in a still pattern for extended periods of use, a slight voltage difference may occur between the electrodes that operate the liquid crystal (LC). The voltage difference between the electrodes increases over time and tends to keep the liquid crystal aligned in one direction. At this time, the previous image remains, which is called an afterimage.
-
Afterimages do not occur when continuously changing images are used but take place when a certain screen is fixed for a long time. The following are operational recommendations for reducing the occurrence of afterimages when using a fixed screen. The maximum recommended time for switching the screen is 12 hours. Shorter cycles are better for preventing afterimages.
