• Antenna Isolator Installation Guide
- Use this to install TV in a place where there is a voltage difference between TV Set and GND of antenna signal.
» If there is a voltage difference between TV Set and GND of antenna signal, the antenna contact might be heated and excessive heat might cause an accident.
- You can improve the safety when watching TV by efficiently removing power voltage from TV antenna. It is recommended to mount the isolator to the wall. If it cannot be mounted to the wall, mount it on the TV. Avoid disconnecting the antenna Isolator after installation.
- Before starting, be sure that the TV antenna is connected.

- Connect to Set-Top box.
Connect one end of the isolator to cable/antenna jack and the other to TV set or set-top box.
"Equipment connected to the protective earthing of the building installation through the mains connection or through other equipment with a connection to protective earthing - and to a cable distribution system using coaxial cable, may in some circumstances create a fire hazard. Connection to a cable distribution system has therefore to be provided through a device providing electrical isolation below a certain frequency range (galvanic isolator, see EN 60728-11)"
When applying the RF Isolator, a slight loss of signal sensitivity can occur.

natural_image
Black-and-white illustration of a cluster of tomatoes with stems, enclosed in a red dashed bounding box (no text or symbols)
natural_image
Illustration of a cluster of tomatoes with dashed lines indicating measurement or alignment (no text or symbols)If a fixed image displays on the TV screen for a long period of time, it will be imprinted and become a permanent disfigurement on the screen. This is "image burn" or "burn-in" and not covered by the warranty.
If the aspect ratio of the TV is set to 4:3 for a long period of time, image burn may occur on the letterboxed area of the screen.
Avoid displaying a fixed image on the TV screen for a long period of time (2 or more hours for LCD) to prevent image burn.
IF THE QUALITY OF THE 3D IMAGE IS NOT ACCEPTABLE, CHECK THE FOLLOWING
1) Viewing distance
For optimal 3D viewing distance, please see the table below.
Please maintain the optimal viewing distance for the best 3D experience.
2) Viewing angle
For optimal 3D viewing angles, see the table below.
3) Check the 3D display sequence (L-R, R-L)
The display method may vary due to the 3D content type. Try changing the display method to L-R or R-L for a better viewing experience

VIEWING 3D IMAGING

WARNING
Viewing Environment
- Viewing Time
- When watching 3D contents, take 5 - 15 minute breaks every hour. Viewing 3D contents for a long period of time may cause headache, dizziness, fatigue or eye strain.
Viewing Age
- Infants/Children
- Usage/ Viewing 3D contents for children under the age of 6 are prohibited.
- Children under the age of 10 may overreact and become overly excited because their vision is in development (for example: trying to touch the screen or trying to jump into it. Special monitoring and extra attention is required for children watching 3D contents.
- Children have greater binocular disparity of 3D presentations than adults because the distance between the eyes is shorter than one of adults. Therefore they will perceive more stereoscopic depth compared to adults for the same 3D image.
- Teenagers
- Teenagers under the age of 19 may react with sensitivity due to stimulation from light in 3D contents. Advise them to refrain from watching 3D contents for a long time when they are tired.
- Elderly
- The elderly may perceive less 3D effect compared to the youth. Do not sit closer to the TV than the recommended distance.
Those that have a photosensitive seizure or chronic illness
- Some users may experience a seizure or other abnormal symptoms when they are exposed to a flashing light or particular pattern from 3D contents.
- Do not watch 3D videos if you feel nausea, are pregnant and/or have a chronic illness such as epilepsy, cardiac disorder, or blood pressure disease, etc.
- 3D Contents are not recommended to those who suffer from stereo blindness or stereo anomaly. Double images or discomfort in viewing may be experienced.
- If you have strabismus (cross-eyed), amblyopia (weak eyesight) or astigmatism, you may have trouble sensing depth and easily feel fatigue due to double images. It is advised to take frequent breaks than the average adult.
- If your eyesight varies between your right and left eye, revise your eyesight prior to watching 3D contents.
Symptoms which require discontinuation or refraining from watching 3D contents
- Do not watch 3D contents when you feel fatigue from lack of sleep, overwork or drinking.
- When these symptoms are experienced, stop using/watching 3D contents and get enough rest until the symptom subsides.
- Consult your doctor when the symptoms persist. Symptoms may include headache, eyeball pain, dizziness, nausea, palpitation, blurriness, discomfort, double image, visual inconvenience or fatigue.

CAUTION
Viewing Environment
