Precautions before using wireless TV
Wireless TVs use high-frequency radio waves of 60 GHz to transmit a large amount of data in a very short time, enabling wireless transmission of high- quality video and audio. The 60 GHz frequency band used in wireless TVs is advantageous for large-capacity data transmission, has good linearity, and is well-suited for transmission and reception in a specific direction. However, if there is a metallic object in the transmission/reception path, the radio waves cannot pass through it. Non-conductive objects (e.g., glass, wood, plastic) may attenuate the signal, resulting in communication failure. Due to such characteristics of radio waves, viewing is not affected when the wireless TV transmitting and receiving antennas are facing each other; however, if there are obstacles in the transmission/reception path, the wireless signal may be attenuated or disconnected, resulting in inconvenience during viewing. This is not a product malfunction. Follow the installation method provided when using the product.

Understanding 60 GHz wireless

**Characteristics of radio waves| Frequencies in the 60 GHz band applied to wireless TVs (high frequency)| Frequencies applied to general wireless communication (cell phone, WiFi/BT) (low frequency)**
---|---|---
Linearity| Strong| Weak
Transmission volume| High| Low
Directionality| Ideal for transmission in specific direction| Ideal for broad coverage
| High loss| Low loss and good
| (linearity)| avoidance (diffraction)
Attenuation| Radio waves|
| absorbed by water| Good obstacle
| droplets and water| avoidance
| vapour in the air|

This product satisfies the standards for protecting the human body against electromagnetic waves. ( Meets IEC 62311 standards)

Wireless TVs use frequencies in the 60 GHz band.

The 60 GHz band is also known as millimetre wave (mmWave), and enables the transmission of large data volumes without delays.
The 60 GHz band is a high-frequency band used in satellite communication.
High-frequency bands have excellent linearity.
High linearity is ideal for transmission in a specific direction; however, obstacles cause greater attenuation loss.
Path loss occurs due to the presence of multiple paths created by diffraction, refraction, reflection, etc. The multiple path loss resulting from diffraction, refraction, and reflection causes antenna transmission and reception failure.
Generally, wireless radio waves experience interference from obstacles.
Conductive obstacles (metal) shield the frequency (antenna transmission/reception), whereas non-conductive obstacles (glass, wood, and plastic) cause attenuation.
Radio waves using high frequencies in the 60 GHz band (short wavelengths) provide optimal image through the use of beamforming technology. Beamforming technology arranges multiple antennas at regular intervals, adjusts the amplitude and phase of the signal supplied to each antenna, and creates an antenna beam in a specific direction to strongly transmit and receive signals to that direction.
For optimal image viewing, the transmission/reception must be facing each other, that is, have an unobstructed Line Of Sight (LOS).
LOS is the visible path, which must be clear of obstacles in the way. If there are obstacles, the receiver must be high enough that it is visible. That is, the receiver must be higher than the transmitter. (For wireless TVs, the Zero Connect Box must be placed lower than the TV Screen.)

Abnormal Display|

If the product feels cold to the touch, there may be a small “flicker” when it is turned on. This is normal, there is nothing wrong with product.
This panel is an advanced product that contains millions of pixels. You may see tiny black dots and/or brightly coloured dots (white, red, blue or green) at a size of 1 ppm on the panel. This does not indicate a malfunction and does not affect the performance and reliability of the product. This phenomenon also occurs in third-party products and is not subject to exchange or refund.
You may find different brightness and colour of the panel depending on your viewing position(left/right/ top/down). This phenomenon occurs due to the characteristic of the panel. It is not related with the product performance, and it is not malfunction.
Avoid touching the screen or holding your finger(s) against it for long periods of time. Doing so may produce some temporary distortion effects on the screen.

Generated Sound|

“Cracking” noise: A cracking noise that occurs when watching or turning off the TV is generated by plastic thermal contraction due to temperature and humidity. This noise is common for products where thermal deformation is required.
Electrical circuit humming/panel buzzing: A low level noise is generated from a high-speed switching circuit, n which supplies a large amount of current to operate a product. It varies depending on the product. This generated
sound does not affect the performance and reliability of the product.
Fan noise: It is a sound made to dissipate the heat generated by the Zero Connect Box, and does not make the product defective.

Precautions for Protecting the OLED TV Screen

Unlike regular LED/LCDs, OLED TVs produce images that emit light for each pixel, achieving a perfect black colour and delivering clear images without blurring. Due to the nature of the organic materials used to achieve high- resolution image quality, OLED displays generally experience image retention on the screen, which can be a persistent phenomenon. This phenomenon is observed in all OLED panels, and although recommended picture modes can minimize image retention, current technology cannot completely prevent this from occurring. Displaying the same image for a long time or repeatedly displaying the same image can cause image retention on the screen, which is a common phenomenon in OLED panel products due to the nature of the product. This product has a built-in screen protection feature. Avoid displaying images that are likely to cause image retention, and follow the recommendations. Images that are likely to cause image retention

Images with black areas on the top and bottom and/or the left and right sides of the screen.
Images whose aspect ratio is 4:3 or 21:9.
Images that are fixed for a long time, such as program number, station logo, game console icon, set-top box menu, etc.
Other fixed screen images or repeatedly displayed images.

Running [Pixel Cleaning] to Protect the OLED TV Screen
The OLED TV is equipped with a pixel cleaning feature to check the status of the screen by itself and prevent image retention that leaves an image on a screen. This feature automatically calculates the optimal execution time based on the accumulated viewing time and is automatically executed when the TV is turned off. While this feature is running, horizontal lines may appear at the top and bottom of the screen. The pixel cleaning feature works when the product is connected to the power cord and main power.

To run this function manually, press the button on the remote control, go to [ ] → [General] → [OLED Care] → [OLED Panel Care] and press [Pixel Cleaning].

Recommendations for Minimizing
Image Retention
When watching the TV for a long time, press the button on the remote control, go to [ ] → [Picture] → [Select Mode] and set the mode to [Auto Power Save], go to [Advanced Settings] → [Brightness] and set [OLED Pixel Brightness] to a lower level. In addition, press the button on the remote control, go to [ ] → [General] → [OLED Care] → [OLED Panel Care] and set the [Adjust Logo Brightness] value to [High]. When showing images with black bars at the top/bottom/left/right side of the screen, press the button on the remote control, go to [ ], and go to [Picture] → [Aspect Ratio] → [User Selection] → [Vertical Zoom] or [4-Way Zoom] to remove the black bars. Turn off the menus for setting up devices such as set-top boxes so that they are not displayed on the screen for a long time.

Note

When the screen is showing one fixed image for a long time, the screen brightness will be automatically reduced and then restored once the screen content changes. This is a normal function to minimize image retention.
